I used all the steps you took for my 2008 Pontiac Grand Prix. The final result was no spark on all coils. Which led me the ignition module being the problem. Thank you ScannerDanner.
I have noticed a lot of mechanics in my area when a car won't start like this immediately jump to fuel pump issues...my 2002 Cavalier wouldn't start and they thought it was a fuel pump and came back and it was the starter had died on it. Replaced the starter and haven't had an issue since. Good video!
Seeing your troubleshooting vids makes me realize I should go out and do most of these tests on a *healthy* car so that I know how it should behave. Simple things like the check engine light I can't even recall if it normally comes on, so I think a good idea for any of us is to get to know your own car when it's working, not just when it is not working.
Great vid, we had a 2004 Jeep Cherokee in the shop the other day that a PCM fuse under the hood that appeared to be fine with an LED test light. This was crank no start. After checking fuel pressure and inj control pointed to ASD relay which, showed weak ground from pcm. Directing us to check some fuses. Found a partially(?) blown PCM fuse with enough contact to light an LED test light but showed nothing or a very dim light on one side of the fuse with an incandescent test light. I use these methods because you keep proving them to be useful. Thanks so much!
thanks paul, really appreciate that u spend the time to show all different way on diagnost driveability problem. some ppl just dont realized that you are a great teacher trying to teach all different method of diagnost car, not just one way. really like to see all the high tech when troubleshooting, make diagnostic so much easier. watch all your videos, learn alot from you with picoscope and snap on scann tool. again really appreciate all your effort.
Still watching as much as I possibly can!! I'm finally at 7yrs ago on your videos I've watched all the others up to this point! It's definitely helping with the knowledge especially since I work at a parts store so I try to pass knowledge on as I'm going so thank you for that bud!
I had the same problem with my Cavalier (fuel pump not running even though the relay was working) This is a great to the point video and did give me some good ideas. But my problem turned out to be different and I'm only commenting about it in case it may help someone else. My fuel pump was not running even though the relay was clicking in and transferring power to the pump. Without going into all the things I tried and tested I'll cut to the chase. I found the ground wire between the battery and the chassis was bad (The ground to the motor was still good) No chassis ground and most things on the car still worked including the engine cranking and the dashboard, but the fuel pump did not. I hope this helps someone.
Thank you. And I wouldn't argue that point but that wouldn't have made for a very good video :-) Also there are some valid procedures in here for the DIYer. What if you didn't have a scan tool? What if the fuses were good? What if you didn't have a wiring diagram and the fuse box wasn't marked? What if you started by checking for spark and stayed on that path, replacing a lot of unnecessary components that had nothing to do with the problem.
working through some contract issues with the school I teach at. no problems just time involved. thanks for your interest in that. I WILL keep everyone informed when it's ready
I spent from 1978 to 2005 doing tune-up and driveability in GM dealers in So. CA. I very much enjoyed you video, I can feel the passion you have in doing your work. I would add just one thing, It might have been a good idea to test the amperage draw along that circuit. Overall fantastic diagnostic structure !!!!!!!!! John St John
Very cool paul on finding the partially broken fuse. I had a similiar problem once with a loose fuse connection myself. I would like to add one detail, paul already knows this, but I don't know if everyone else does, you can read 12 volts on both sides of a fuse and the circuit can be unloaded, then as soon as you have current flow the voltage drops on the other side of the fuse, as shown in the video, this kicked my butt once, so as an extra measure I use my loadpro leads to load the fuse.
Great direction tests, I've used the check engine light one a few times in my career to find faults. Keep up the 'out in the field' videos Paul... Great stuff!
i have a 1999 Isuzu Trooper or as we call them in australia Holden Jackaroos and they have a feature built into the tech2 where even if the MIL Light isnt lighting due to blown bulb for example the tech2 can actually inform you if that fault condition is indeed set same for airbag light we get alot of people removing bulbs for roadworthy inspection and the tech2 has caught them out every time for ANY GM Vehicle i encourage people to arm themselves with a tech2 :) great tool
Right to the point and explained in a way a dummy could understand it. Thank you for your sharing of useful knowledge. At least now I know where to start on my vehicle.
Thank you very much. I have over 100 videos on youtube now and am doing some things with an eBook and video lectures on my website. keep watching the youtube stuff and you will see the link. Thank you for your service my friend!
Thank you. I used your video to fix my 2002 S10. Your explanation is to the point, logical in the correct order of diagnostic and very useful. My little 2.2 engine only has just 66,000 miles but stuff pops up. Yesterday I got in and started the truck to go to the park with my wife and daughter. The truck ran for a few seconds then just sopped. I noticed the shift indicator didn't eliminate over the PRND21 deal, and the fuel gauge didn't work. I'm no pro, but have one of those diagnostic testers which I hooked up to see no communication. I had no idea what to do at the time, so I searched the sea of forum thoughts which generally lead to land of nowhere. Fortunately I found your video the next day. My problem was simply a blown ECU fuse in the engine compartment. I found it with my electrical tester, put in a fuse and bink! on came the illumination over the P, the fuel gauge went up and she fired right up. Thanks man!
Awesome Greg. Don't forget, that fuse blew for a reason. My suggestion is keep some extras with you in case it happens again and DO NOT put a bigger fuse in as the "fix". A 5 amp higher than normal to get you home in an emergency situation only and if that blows, get it towed.
ScannerDanner Premium For sure. Thank you for another sound suggestion. It;'s amazing how glitchy these little trucks are given the low miles. This one was driven by a grandmother for the first 62,000 miles in Arizona were it doesn't see snow and very limited wet conditions. It looks clean and orderly, but still it has goofy stuff that pops up. It is 13 years old I guess, so I understand.
I was taught to check fuses first , but it is hardly ever the fuse . there is way more value in looking at the system as a whole that way depending on symptoms you know which way that you want to go that will be the fastest to diagnose . great video
Great video and tutorial on "Logical Step-Through Troubleshooting". Big thumbs up. Im dirt diving a NoStart on a '99 Honda CIVIC Si (has spark, fresh plugs, pump, cap, rotor wires and all with tons of spark. I'll grab some NOIDS and see what I can on the injectors. ("Coughs like an old radial engine that attempts but never catches and cranks) Plugs go sooty black after each attempt The word that comes to mind is VEXING! I'll check out the "Honda No Start" and see if I can glean anything from it. Keep up the great work/videos. BP
Good Afternoon ScannerDanner take care and have a great day ScannerDanner God bless you As always Great tutorial 👍 👌 👏 From Nick Ayivor from London England UK 🇬🇧
ScannerDanner, I've looked at more than enough videos for my Chevy Cavalier; I would have to say your logistics is outstanding to say the least. Information was superb. Hope you will have a series of videos to come, because I will recommend it above all. If you created a subscription I'm on board. Thanks- Former Marine.
as for the low beams that are not working, there is a wiring harness connector that runs underneath the driver side frame rail. you have to take the driver side inner fender apart and remove the washer bottle. you will find the wires broken in this location. if I remember correctly the low beam control wire is blue
My old vantage is version 6.0 but I still use it all the time even though the data base only covers me until 2002, the function of the tool is never obsolete
Good... the clue was in the lack of comm.…. using a DLC break-box to me was the way to go. DLC pin 16 and the mirror fuse was the solution. thankz for your super videos... hey, do you accept donations?
Hi, Paul I really like your videos and the way you explain them. Looking forward the next one as there is always something new to learn. Much appreciated.
Good point on not jamming the probe in a connector and spreading the pin. I also hate "fuse taps" the type that hooks over the fuse blade and in doing so doubles the size of the fuse blade. I have run into it causing problems after the fuse tap is removed, the fuse won't make a connection from the terminals being spread apart.
I got a pack of 50 at walmart. They are in the sewing/crafts section. While there, pick up a "seam ripper" safest way to open up a wiring harness without causing more damage. They come in two sizes there, I prefer the smaller ones.
And greetings to you too from Pittsburgh PA! Thanks for the comment and if you do end up buying my eBook, you will not be disappointed. Have a great day.
thanks bro,i dont know why i didnt think of walmart.i knew they were sewing related just didnt think about it.thanks for the seam ripper idea too,it will save some time and headache.GOD bless!
Hot damn that was a great video i had a 99 grand am with a cracked window sitting in it on lunch break in the rain kept hearing a psst psst psst like water dripping on a hot stove i was like what the hell looked down and saw what looked like smoke coming from the crack of the door and freaked out opened the door and my whole fuse box was full of water and steaming like a coffee pot so allthe relays and fuses were all rough and sorta cooked looking it didnt matter in end catastrophic timing chain failure
awesome video! my 2008 suzuki xl7 2wd did not start/crank after i gave a guy a jump start. had to tow my car to my place. some karma smh... i got all the lights on the dash, so i changed the starter. then i had to travel on business. i may have wasted money and time since i also had to remove part of the exhaust system. i'm worried that my computer fried, but i'll find out this weekend. definitely going to re-watch this video and your two-part no start no crank (detailed map vid) before i give up and take my car to the shop.
Okay, say all of your fuses are good. Then what? There are times you will want to know how to do this reference voltage test and why I did it here. Check out my Honda Element no start video and you will understand why better. You are not wrong in your thought process my friend. And I could have done as you suggested first. But this 5v ref test is very valuable and I wanted to show it.
ScannerDanner, you give great video... 2004 sufire, similar problem, no spark, no fuel. I was following along and when you got to the engine compartment fuse box, your small fuses (like the PCM) were hot. Mine however do not light a test light. All the large fuses do, just the small fuses are dead. Any ideas? Does passlock shut down both fuel AND spark, I can't seem to find a definitive answer on that? If you happen to answer, thanks...
Then you have a voltage drop problem in the ignition switch or in the wiring to and from the ignition switch. If you can tell me the exact fuses that are reading 7v, I could probably guide you further.
Well that's what we did we change the coil change the module change the crank sensor and still don't get no fire do not we're going to go check that fused the one that you chat thank you very much I sent the video to my son she'd the mechanic I'm the supervisor
I should of watched the whole video before commenting. That 10 amp fuse you showed that was discolored. That is exactly what I've seen on fuses that had a fuse tap on them then removed, that terminal ends up being loose and causing a high resistance connection, And you know the result.
I have a 2001 chevy cavalier it isn't an all electric car it has roll up windows no anti-theft system from what I know. My issue is I keep having trac off problems with this car. I tested the throttle position sensor with my multimeter and it wasn't that. I replaced the spark plugs and it wasn't that what do you think it could be ? Also I have two wires dangling from the alternator where do they go and is this affecting my car any ?
I've had a lot of vehicle with a no check engine light. I guess this is off the subject and a few years late. Well, I always tell people to check that the Check Engine Light comes on when they turn the key on before they start the car, if no light then don't even bother with starting or buying the vehicle. My latest was with a family member. He bought a car without listening to what I have always stated. He called me saying he bought a car and he loved it and that he took it around town and no light came on. I asked him again did any MIL light display before he started it. No and that the car runs fine. 2 days after his purchase he calls me and says he needs my help. So I pretty much knew what one of the issues I would be dealing with before I got there. I told him that one problem he is dealing with will be a CAT issue and no telling what else. {He also stated over the phone that No Lights still weren't on.} So after getting there, it was the CAT that had actually melted down and plugged the exhaust. With about 1000 other codes that was triggered. Long story short, the local dealer removed the MIL light to cover up the faults that the car had. Scammed into buying a Lemon. Also before I end this, I've also advised my people to also pull the E Brake also once the car is started. Had a car come in where someone rigged the MIL Light to the Brake Light. Sorry for the rambling.
mine real start most of the time but it keeps stalling out...when u stop it quits...get it restarted quits again..i cannot get it out of my driveway to have it check out...
Hello, I got a good one for u my car died couple days ago andwhen I open the hood there were oil Al over the top of the engine the spark plugs were smothered in oil I took off the plugs completely dry ,there was spark but still no start ,I think the valve cover gasket might be leaking or the head is cracked what could I do..I need ur help big time
Ah that's because that is the alternator main battery cable. Your system is not charging without that wire being hooked back up to the starter battery post
I have a 2000 cevey cavalier it was driving fine then i let a friend use it now it won't start the lights come on bright the oils are good it sound like it want to start but it won't someone said it might be the fuel pump but it look like it's in good condition
Crissy Robinson I have a 2001 cavalier and it did the same thing turns out it was short of ground you need a cable conected to the negarive pole of the battery and run it to the engine block and from the block to any place in the chassis and believe me it will start
I have a 2002 Chevy Cavalier my car is kind of doing the same thing but with that I noticed the anti theft light is not coming on at all even when I try to make it come on it won't my car starts up and then two seconds it dies runs great for the two seconds change the fuel pump and its weird it started ran fine once I shut it off and then tried to start it again it went back to doing the same thing any ideas?
The start and run for a few seconds sounds like a typical GM passlock failure. Unlike older GM's your key does not have a resistor however the lock cylinder has a similar feature when your cylinder is turned with a key it flips a magnetic switch that verifies the cylinder is being turned, IE you are not hotwiring the ignition switch. At the lock cylinder there is a connector three wires Black - Ground, White (sometimes red) 12V (Bulb check) and a Yellow which is 5 volt signal if your signal voltage is bad it means a wiring problem or a bad BCM (BCM controls the antitheft in 01 - up cavaliers, 00- down is the IP) the BCM is located in the Drivers left footwell under the dash However the most common problem with the Passlock cylinders is a bad connection due to corrosion at the lock cylinder connector clean the pins the best you can with electrical contact cleaner your other option is to add a resistor between ground and the yellow 5 v reference wire which bypasses the lock cylinder, you can OHM the cylinder to get the value or you can buy a remote start bypass from a company like DEI for $15, if you replace the lock cylinder (a waste of money) you will have to do a passkey relearn, but thats an issue for another day.
hey man good video, I just bought a used 2002 Chevy Cavalier, I was already aware it may have some problems but after watching this video im wondering if I could solve some of them, ive got a few questions...the headlights arent working but the brights are, also its been brought to my attention that theres an idoling problem..i even saw it when you started the car in this video, can i check these things through the fuse box? or is the problem bigger? please it would be helpful if you respond
Mr Danner, Say for example the PCM was fried on this vehicle, and you go to replace it. How can you be sure it wont fry again, right away or maybe in a week? Would one have to go looking for a high amperage draw component(s)? What is your thought process or plan of attack?
@amfam12 man I hope they keep ancient for a lil bit longer.. I don't know if you notice but they are giving more control to of a vehicle to a computer.. Technology for these vehicles are growing by leaps and bounds you can see it in every decade.. I really think they are trine to phase out the internal combustion engine with that hybrid shit.. 30 40 yrs from now the internal combustion engine will be sitting in the museum next to the steam engine.
Paul what do you think of the OTC 3840F 2-Channel labscope? I was thinking about getting one of these. What is your opinion on the price and functions of this scope compared to something more expensive. I realize you have probably never used it, but what do you think of price and functions based on what is advertised?

Hi, Paul
I really like your videos and the way you explain them.
Looking forward the next one as there is always something new to learn.
Much appreciated.
A great overall troubleshooting chart. Like you said every car is different.
Wow I will try this because everything that was wrong with that car is going on with my 2003 Chevy Cavalier hope it works.
Good point on not jamming the probe in a connector and spreading the pin. I also hate "fuse taps" the type that hooks over the fuse blade and in doing so doubles the size of the fuse blade.

really smart knowledge breaks it down for you different ways of checking a check engine light not turning on
No, this is one of my established customers. They are primarily a body shop and don't even look at these types of problems. They call me first.
My Fords from the early-mid 90s have had fuse diagrams - When the cover is intact, that is ;)
thank you so much,i just had the same problem on my 2004 and when I touched the same fuse you did it started up
And greetings to you too from Pittsburgh PA! Thanks for the comment and if you do end up buying my eBook, you will not be disappointed. Have a great day.

IF you're lucky, there may be a Maxi fuse that blew. I know Honda uses a 100 amp maxi fuse, maybe Suzuki does too.
Very instructive, thank you.
Okay, say all of your fuses are good. Then what? There are times you will want to know how to do this reference voltage test and why I did it here.
Check out my Honda Element no start video and you will understand why better.
You are not wrong in your thought process my friend. And I could have done as you suggested first. But this 5v ref test is very valuable and I wanted to show it.

I looking for the fault code 0562 system voltage low and the different resions..but I didn't find ...
Scannerdanner you are the man! Love your vids, keep 'em coming bro!
What is the voltage reading on both heavy gauge and light gauge writes on the starter during cranking?
Outstanding as always Paul!!

just the GM type 2 ignition coils. this test can get you in trouble on other designs
Love your discuss in not LabeLing fuse boxes share a passion for it myseLf
Well that's what we did we change the coil change the module change the crank sensor and still don't get no fire do not we're going to go check that fused the one that you chat thank you very much I sent the video to my son she'd the mechanic I'm the supervisor
what is battery voltage while some of the fuses are reading 7v?
thank you life is a learning progress
very helpful my neighbor had this problem now i know war to look for thank you
Brilliant case study!
I should of watched the whole video before commenting. That 10 amp fuse you showed that was discolored. That is exactly what I've seen on fuses that had a fuse tap on them then removed, that terminal ends up being loose and causing a high resistance connection, And you know the result.
Much appreciated Bro, keep up the great work.
Thank you
Very good video, very helpful! Thanks!
That was an easy fix. good job.
Thank you for another awesome video..
So have you heard anything from the customer about the car or is it still fine?
I have a 2001 chevy cavalier it isn't an all electric car it has roll up windows no anti-theft system from what I know. My issue is I keep having trac off problems with this car. I tested the throttle position sensor with my multimeter and it wasn't that. I replaced the spark plugs and it wasn't that what do you think it could be ? Also I have two wires dangling from the alternator where do they go and is this affecting my car any ?
as soon as you had a no communication issue with your scanner you should immediately have checked for a blown fuse
I've had a lot of vehicle with a no check engine light. I guess this is off the subject and a few years late. Well, I always tell people to check that the Check Engine Light comes on when they turn the key on before they start the car, if no light then don't even bother with starting or buying the vehicle. My latest was with a family member. He bought a car without listening to what I have always stated. He called me saying he bought a car and he loved it and that he took it around town and no light came on. I asked him again did any MIL light display before he started it. No and that the car runs fine. 2 days after his purchase he calls me and says he needs my help. So I pretty much knew what one of the issues I would be dealing with before I got there. I told him that one problem he is dealing with will be a CAT issue and no telling what else. {He also stated over the phone that No Lights still weren't on.} So after getting there, it was the CAT that had actually melted down and plugged the exhaust. With about 1000 other codes that was triggered. Long story short, the local dealer removed the MIL light to cover up the faults that the car had. Scammed into buying a Lemon. Also before I end this, I've also advised my people to also pull the E Brake also once the car is started. Had a car come in where someone rigged the MIL Light to the Brake Light. Sorry for the rambling.
Thanks for sharing!
very helpful thank you very much
mine real start most of the time but it keeps stalling out...when u stop it quits...get it restarted quits again..i cannot get it out of my driveway to have it check out...
Can't believe GM was using that ancient 2.2 as late as 2002.
Nice diagnose ..keep it up
Thank you.
Thank you
Well done, were you called out to a shop that could not figure it out ?
Hello, I got a good one for u my car died couple days ago andwhen I open the hood there were oil Al over the top of the engine the spark plugs were smothered in oil I took off the plugs completely dry ,there was spark but still no start ,I think the valve cover gasket might be leaking or the head is cracked what could I do..I need ur help big time
It turns over but it wont start just before it died it waz making a loud tic then it died and never been running sense
yes it does and it only reaches to the same place and the battery light stays on now it is also in the same black covering
Ah that's because that is the alternator main battery cable. Your system is not charging without that wire being hooked back up to the starter battery post
great vid as always bro!b..t.w. where do you get your t pins from?thanks bro,GOD bless!
very good video to lenr
Thanks Paul!
this is a good example , using the fuse ,why you don't probe the front ,you spread pins or pour connection when you plug back in?
Can bus I saw this like seat belt air bag systems. All the buss have to be functional for diagnostic
I have a 2000 cevey cavalier it was driving fine then i let a friend use it now it won't start the lights come on bright the oils are good it sound like it want to start but it won't someone said it might be the fuel pump but it look like it's in good condition
Crissy Robinson I have a 2001 cavalier and it did the same thing turns out it was short of ground you need a cable conected to the negarive pole of the battery and run it to the engine block and from the block to any place in the chassis and believe me it will start
Watch my video on "Ford C.O.P Ignition Testing (2003 Expedition 5.4)
could be a lot of things. a vacuum leak is one of many possibilities.
I have a 2002 Chevy Cavalier my car is kind of doing the same thing but with that I noticed the anti theft light is not coming on at all even when I try to make it come on it won't my car starts up and then two seconds it dies runs great for the two seconds change the fuel pump and its weird it started ran fine once I shut it off and then tried to start it again it went back to doing the same thing any ideas?
The start and run for a few seconds sounds like a typical GM passlock failure.
Unlike older GM's your key does not have a resistor however the lock cylinder has a similar feature when your cylinder is turned with a key it flips a magnetic switch that verifies the cylinder is being turned, IE you are not hotwiring the ignition switch. At the lock cylinder there is a connector three wires Black - Ground, White (sometimes red) 12V (Bulb check) and a Yellow which is 5 volt signal if your signal voltage is bad it means a wiring problem or a bad BCM (BCM controls the antitheft in 01 - up cavaliers, 00- down is the IP) the BCM is located in the Drivers left footwell under the dash However the most common problem with the Passlock cylinders is a bad connection due to corrosion at the lock cylinder connector clean the pins the best you can with electrical contact cleaner your other option is to add a resistor between ground and the yellow 5 v reference wire which bypasses the lock cylinder, you can OHM the cylinder to get the value or you can buy a remote start bypass from a company like DEI for $15, if you replace the lock cylinder (a waste of money) you will have to do a passkey relearn, but thats an issue for another day.
hey man good video, I just bought a used 2002 Chevy Cavalier, I was already aware it may have some problems but after watching this video im wondering if I could solve some of them, ive got a few questions...the headlights arent working but the brights are, also its been brought to my attention that theres an idoling problem..i even saw it when you started the car in this video, can i check these things through the fuse box? or is the problem bigger? please it would be helpful if you respond
Sharp Brother :)
common to have multiple fuses for a PCM
Thanks paul
buen video
Thanks a lot for sharing it.👍
Mr Danner,
Say for example the PCM was fried on this vehicle, and you go to replace it. How can you be sure it wont fry again, right away or maybe in a week? Would one have to go looking for a high amperage draw component(s)? What is your thought process or plan of attack?
Fords fuse reference is in the owners manual
@amfam12 man I hope they keep ancient for a lil bit longer.. I don't know if you notice but they are giving more control to of a vehicle to a computer.. Technology for these vehicles are growing by leaps and bounds you can see it in every decade.. I really think they are trine to phase out the internal combustion engine with that hybrid shit.. 30 40 yrs from now the internal combustion engine will be sitting in the museum next to the steam engine.
same thing happened to me. i put conduction grease on it and never happened again. I always go for the fuse box first on a no start problem.
good video, traslation on ispanish
Paul what do you think of the OTC 3840F 2-Channel labscope? I was thinking about getting one of these. What is your opinion on the price and functions of this scope compared to something more expensive. I realize you have probably never used it, but what do you think of price and functions based on what is advertised?
