Truck cut off 1/4 mile from work in the snow. Checked the ignition coil. No spark. Went to the fuse box. Blown 15A fuse off the relay. Worked a full day and made it home with no problem. Thanks. This video was key to troubleshooting.
Let me be the first to say: Dude! You did this so beautifully. Explain showed pointed out…the works. Damn man, just thank you dude. You’re a TH-cam hero 🤙🏽
He's not a hero. He's a sub or a hoagie. 😂
Hands down one of, if not best video I have seen. It was informative, enjoyable, easy to comprehend. For a minute or so, actually thought I was right there hands on training. Thank you, look forward to checking out other videos..
Thank you so much. The jumping over the starter relay was a huge help to me as I was working on it by myself. May be common knowledge for some, but I did not know it. I knew I had power and getting fuel, was pondering about checking for spark. I have this engine in a 1500 silverado. Turned out my d-cap cracked under one of the two screws and let in moisture. All posts were corroded and button burned out.
Unfortunately, 2 days later I am right back where I was.
Got a 2000 Silverado 4.3. Been sitting for years motor was locked up got it free but no spark. Thanks for the video will try this in the morning
Did this work for you
Sir I want to thank you so much for you posting this video.My daughters truck was plagued with starting wont start.Followed your vid and now its fixed.Thank you again.God bless.
Thank you, sitting in my truck and the same situation and you showed me my problem. Very much appreciated
This was a killer easy explanation step by step of how to diagnose a no spark issue with ease. Thank you. I fixed my issue.
My S10 fought in WW2 and during hand-to-hand combat with a 109 ft field-mouse that had a really interesting personality and a family back home with multiple hanging plot points heavily reliant on whether or not their dad returns home from the war...
Why didn't I watch this video 2 WEEKS ago???!!! I checked for spark and fuel but didn't think of distributor. Same symptoms so I am about to check that. I immediately subscribed and liked video. Thanks man!!!
I bought $300 worth of electrical parts only to find is actually was my distributor which i installed incorrectly.
Then yesterday i re installed it and hit the jackpot. The timing has never been more smooth. My engine went from sounding like a dying moped, to a quiet running van. 😂🎉 Im so happy i got my van back.
Done all this has spark on the coil no spark on the plugs. Put 2 new distributor caps and rotors on so im still stumped. Very good video!!
Great job you explained everything in a very clear manner great tips thanks for the info and help
Thank you so much for your video!! My GMC Sonoma 2003 started working again
Exactly what my s10 is doing. I will try this fix.
Thanks!
Same 😭😭 Did u get it fixed?
This video literally saved our 96 GMC Sonoma! Thanks!!
Great video! I have a 97 blazer with the 4.3. It does the same thing as this was doing however it normally will fire off starting fluid. I haven't tested fuel pressure yet. But once I test pressure how do you determine if it's the injectors or the pump that would be bad?
This is what I need the answer too as well!
The s10 is a great all around truck!
Hi, my 99 s-10 p/up 4.3 is doing the same thing. I checked to see if it was getting fuel thats ok, then I removed the spark plug wire from the coil and lots of spark even from pretty high above the coil and put the spark plug wire back on and the truck started right up. I played with the wires all around the coil to see if I could get some kind of reaction from the engine but it ran smooth as always. I am now worrying about it happening again at a bad time and get stuck somewhere. PS, I changed the coil,wires,cap& rotor and pvc valve. Cleaned M.A.F & throttle bodie & new fuel filter all at 5000 mile ago.

Mine was starting to fail and finally did. I hop this helps
I had the exact same problem! This video was very helpful!!
Had the same proplem fix in 20 min.had a acell cap and rotor ready at home.brakes went out front line leak new line but left hood cracked and got moister in cap four year old it was a replacement distribitor.it had a same quality cap as the one i replaced it with.219000 milles she's a runner i drive it to buy parts for my seabring.2002.the chevey trusk is a 1997 s10 4.3l x motor.
Thank you so much, extremely helpful
I love the explanations but my mom's 2004 Blazer is doing the same thing and I've replaced everything I could think of except the crankshaft sensor which dad is the only thing I haven't replaced yet other than the stuff you mentioned
By chance was it backfiring and not starting? Mine i replaced everything bur the crankshaft sensor and it won't start and backfires out the intake and exhaust so ima replace the crankshaft sensor
@7:30. Orange spark is weak and coil may be failing. Blue spark is strong and coil is okay. Color shows temperature of ionized air of the spark gap. Blue is hot, orange or yellow less hot. @9:48, rat droppings on distributor cap can mean chewed wires. Rotors have asymmetrical mounting lugs underneath to prevent installing 180* off.
Gives me something to try. My Blazer it's like the key was just shut off roll and roll over kick back once and awhile just like this one did. I'll be giving this a try. Thank you very much.
Have an 02' Blazer ZR2 & drove it to the store & got back in & nothing! It would Crank but not start.
Luckily I took it to a Mechanic that knew about 4.3's & he checked the ECM & Coil.
He found that it was cracked immediately & replaced it & I was on my way..
First let me say your video spot-on. But I've got a problem 97 S10 doing the exact same thing as your client in your video I changed my distributor and it was ten times worse than your clients but my S10 still will not start. I have no clue what my wife done to it
You did great job explaining it. Hope that's my problem also
I've definitely needed someone as knowledgeable as you. Brother if possible I have a question regarding a 2000 chevy truck 4.3 the exact same thing won't Start but on my end am not getting any sparks when checked.
I am having this same problem. I will let you know if these trouble shooting methods help me fix it.
I like ur methods ty and ur quality mechanics
@7:30 you have the spark colors swapped. Blue/white spark is a sign of much better and hotter spark than orange or yellow.
Great diagnosis video. Helping a neighbor swap a fuel pump in his S10 next weekend and been watching some basic diag videos just for a refresh of the process.
Nice, no expert on TH-cam. I believe you did great.👍
Add on idea:for car owner diy'ers: check some spark plugs if badly worn, then also replace spark plug wires with as well. Put dab dielectric grease on each plug boot.
This is the extra care the dearlership mechanics do when working on thir own cars.
(Mo commisioned service mgr breathing down their neck to maximize profit by rushing the tech , while still overcharging the poor customer).
Parking brake on will avoid daytime lights going on and help recharge that nearly dead battery.
Great video! Thanks for your help. Very helpful
My 96 4.3 was doing this other day. Found it to be fuel filter. Dead giveaway was fuel leaking from under driver door.
Got my S10 Chevrolet 1999 manual for 7 months first I go my Life don't nothing b it do to me 3 time oready the 7 months I got it driving oraung the house to store got 5 minutes to store's coming back trays to stared it like 3 time no want to stared way like 3 to 8 put the key put stared ogain don't the 7 mont got it do to me 3 time only any body know can be thank bro good vídeo 🔥
Just installed new fuel pump /charcoal canister. Truck started right up drove for hour. Came home and won’t turn over.99 s10
thanks bro bout to try this tomorrow wen i buy this truck i think thats wats wrong with it good locking bro
great video and very well explained thank you bud keep up the good videos.
Should have replaced the camshaft sensor while you had it apart
Hey dude you're the best man you got my car running right I did what you told me and I did it and that got it right
I appreciate the information. Thanks!
My blazer has the same problem. The bad thing is I have the intake already off to replace the fuel pressure regulator and spider injector 😢
It’s the ignition module my truck had the same thing
My GMC Sonoma 2002 will run if you put gas in the intake and I here the fuel pump coming on and I got good fuel per set up to the line but I do not no if the injectors work
awesome video, thank you sooo much, im going to try this stuff tomorrow on mine
I got shocked pretty hard doing this even tho I knew better 😂 then I get to the part where he says be careful not to get shocked 🤣🤣🤣
I'm hoping this is my problem. Lot easier than testing coils n stuff
New tank, sum new lines, new filter, 4.3 will only start with a shot in the throttle body, then when that is gone, dies. There was fuel in the new filter. I hear the pump when i turn key. Spider injectors maybe?
Very helpful, great video!!
Thank for the video👍🏼 help’s me
Thanks for your video it ready helps..
Thanks great video i have a question does the radiator fan always run even when the engine is cold
I have watched several videos on 4.3 no start and have seen different ways to check for spark. Does nobody own a timing light anymore?
Timing lights are cool and what not but pulling a boot off of a spark plug, remove spark p. Plug spark p back in boot , rest electrode against exhaust manifold, turn ignition sticks , if you dont see spark there , start backtracking …same ol shit, different century.
so much good information thank you
great video
Mine will start sometimes for like 1-3 seconds and just straight die.
New cap,rotary button,plugs and wires
Has spark and fuel pressure
I'm stomped
What do you do if you put a new crank shaft sensor, cam shaft sensor, cap and rotor on and it’s still cranking but won’t start
Coil pack is the main source of apart and multiplies it in the distributor.
Might have to perform a relearn. A lot of times the sensors you buy are honestly bunk cheaply made ones and there junk out the box. If you ohm test the sensor and you have power ground and a signal to the connector. If that don’t work I’d recommend looking into the PCM.
I already did cap and button and coil and coil wire and fuel pump but still won't start. Getting fire at coil and getting gas. What's wrong? It died going down road
Same here did you figure it out?
@@christianmaldonado9068 crank shaft sensor
I have a Chevy s10 it starts and everything I hear the humming sound for fuel pump. But it stalls while driving and on incline
How would I know if it might be a battery? My wife drove home last night no problem and then went to drive again to goto the gas station and it wouldn’t start. Acted like the battery was low.
I tried starting it today. I can hear the fuel pump priming. I hooked up a jumper battery but it still wouldn’t start and basically drained the battery.
Should I take the battery to autozone and get it tested first? I’m wondering if a bad battery would cause the symptoms. If it was alternator, it should have at least jumped off
I m have the same problem would that for my 1999 Oldsmobile bravada
Hey I have a 99 Bravada too. But no spark. Did you figure your out?
I have replaced fuel pump, cap and rotor, coil pack, fuel filter ignition switch and checked all my fuses and still no luck
Thanks for the video. You solved my problem
Maybe ne t time your trying a tutorial..."T for Torx" so that soccer mom can ask for the correct tool...yes- t for star.. OK, male spline, male 12pt, 11pt. Guess an E20 is a supernova bit, as it's a hollow "star"?😂busting your balls but I honestly wasn't expecting "T for Star".. good job. On my 7th s10, only ever had to do one cap+rotor , on the OTHER HAND-cant count the Delphi ICMs I've replaced, or Dragonbreath mafs, ebay coils, also have actually been required to update 1 to mpfi from spider, the rest were strictly upgraded for puececif mind. Also sidenote- most good quality wires cone premarked
Mine still isn't starting, we followed all the steps. Any other ideas? We also changed the fuel pump and the crank shaft sensor.. we are at a loss of what to do
Thank you very helpful
Awesome video - you really helped me out
That was a great and helpful video. Thanks so much!
I have a Chevy S10 truck is doing the same thing to the think it's a 6.0 wonder is this and work on my truck if I tried this and see if I had to get any other parts I put a new alternator and a new battery in a velvet Saturday and then Sunday or Monday last week I talked you started and it's acting up the same way
Un muy buen video, mil felicitaciones..
I have a 1996 GMC Jimmy 4.3 l vortec sometimes I have a starting I also replaced the fuel pump on my 1995 GMC Jimmy and it won't start sounds like I need a new distributor please let me know any troubleshooting I may have to do
⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️⚠️😀Take high heat silicone and mix it in a spray bottle with alcohol to thin it out so its sprayable. Then cover up all metal points and the middle button with masking tape and then spray the entire cap, inside and out and let it dry.
Remove tape while still wet.
Your distributor cap will be coated with rubber like a glove and the cap is not insulated and water proof.
The silicone will cover the micro cracks and any pours in the plastic of the cap. Preventing arching. Also preventing corrosion from outside moisture.
I bet it would last way longer. 😎 Try it.
I did that to my entire coil.
I covered it in silicon all over, except for its electrical connections.
So after doing all that getting it TDC placing the distributor at the 6 sill not working buying another distributor same issue at this point should I be looking at the chain jumping a tooth ?🤔
After installing distributer now my 2001 gmc Sonoma will not start any ideas ?? And is there a diagram on what wires connect to the distributor ?
Excuse me can you let me know where is the cap and rotor I have the same problem with my truck Chevrolet S10 2001 4 Cilindros 5 speed we changed gas pump, spark plugs, cables, Thermo state, when I put some starting fluid started but take about 20 minutes when the motor is hat started easy.
Mine is a 4cyl 2001.. fuel pump wasn’t coming on so I bought a new one and it’s not coming on either.. I haven’t tried starter fluid yet.
Relay or fuse
Possible bad wiring
It kept blowing the ecm fuse before this happened.. all relays and fuses are fine
@@demonlust75 did you figure it out?
@@brodakblack3392 no I’ve been working on the road since I posted that comment
I bought a 2000 Chevy s10 & it overheated & now it won’t crank or nothing
Whey what's up I have the same issue with my 2002 chevy s10 ls 4.3 it cranks and no start I pulled the code p0335 I changed the fuel pump and fuel filter and now it's not starting
I got an 03 s10 I've changed distributor cap button timing chain throttle body position sensor crankshaft sensor ignitor coil ignition control module and a few other things but still won't start...any help?
Cool bro thanks
-97S10 pick up truck turns over cranks but it will not start until the - lights comes on I'm sawin what do you think the problem miss
My cap and rotor look fine though? There cheap so maybe I’ll just throw one on there too see
Sweeeeet. Nice job fella. THANK YOU.
I think you got it backwards red or Orange Park is bad blue spark is good
No spark coming from the coil to the distributor what could be the problem
2001 s10 4.3 was running fine then sometimes fuel pump wouldn't come on with key so i replaced ignition switch now fuel pump comes on. But still no start sometimes it will start but only runs 5-15 sec before it quits any thoughts on what to check i did also change coil pack
it starts on start fluid but will not stay running and if u push on the pedal while trying to start it it floods and will not fire for while afterwards just rolls over
thanks
coca cola is bad for you, thats why i drink beer when i do mechanics 😳🤣✌
That is me as well
"... Thats why I drink beer when I do mechanics." Put that 5th of Vodka down! You cannot even type proper ENGLISH! People like you create a bad reputation for us Technicians !
Dislike
Need a beer to work on these
😂
No spark from coil area what should I do we changed head on s10
My 97S10 pick up truck V6 doesn't have a few of the Box like other ones that I'm saying I don't know where the relays are the beatbox is on the left hand part of the dashboard I do not understand where are the relays
Mine would crank but not start every few days charged the battery kept trying ended up being fuel pump relay! Crank wont start new battery dead after a few days in a shop (fuel relay)
My '91 S-10 4.3L will turn over but won't start. It's getting spark and fuel. Checked distributor cap. No cracks or moisture. What else could be the problem. Help! Please. Thank you.
Have a 99 Sonoma 2.2, and won't start...have changed fuel filter spark plugs, wires, and ignition coils, but doesn't turn over; fuel pump is working...
Wat if the distributor moves a little like u said that's bad.....
Mine is doing the same but I changed my whole distributor what could it be
What causes the battery on my Chevy s10 to go dead even when its not being driven?
Hey bro would a code reader tell you that is the problem?
Question for fellow truckers… can my 2001 s10 2.2 have this issue or is it only on the 4.3s?
You had me at "aha its whatever" lmaoo
Perhaps add in it's MPI and not throttle body.
what if you get no spark from the ignition coil
