This is exactly my engine. My truck sounds just like yours did in the beginning of the video. I bought a new distributor cap, rotar, plugs and wires. Replacing it all tomorrow. Hopefully...
Thank you so much for your detailed video and explanations. Just had my truck do this to me this morning and now I atleast have somewhere to start to fix it.
I had a 2003 silverado that would turn over but no fire. I had millivolts at coils and a ground . I put a crank sensor-in it . No help . I then pulled cam sensor . I could lighty smell burning wires. I checked the plugin to cam sensor . We had pulled intake and put knock sensors in . Upon plugging the sensor back in after putting a new oring on it . The plugin got twisted and the 3 wires were bare 1/4 behind plugin . They had welded themselves Together in that twist .I pried them apart with a razor blade and taped them up . Engine fired up and ran fine .
Drove to work, got off work, truck cranks, no start, spark and haven’t confirmed fuel pressure yet. Now that I think about it I only checked one plug wire and it sparked about the right amount of times equally so it seemed normal. My spark plug was actually loose af and I hand tightened it back in. My ECM ign fuse thats “always hot” turns off during crank but the spark was still sparking. Thought maybe ignition switch but who knows anymore. Im going to buy a fuel pump, cap and rotor, starting fluid, rent a fuel pressure gauge and try to fix my truck in front of the customer’s house tomorrow. 😂. Thanks for the info. I looked for a way to see if I had fuel pressure but I didnt know it was hidden back there. I was literally looking right in that area. Im by myself and I dont have a fuse box under the hood. (1995 jimmy). It makes it impossible to listen for a fuel pump noise. Had a check engine light come on last summer for a cam sensor I think. It was under the distributor. The light stayed on ever since. Last few months it would lack a lot of power especially in the 1-2 or 2-3 shift. Gas mileage seems ok(15mpg city) so hopefully its simple bc I just got paid and that money is now possibly gone😂😂😂.
@@jackpaullus2643not sure. I replaced the distributor coil and cap. Started up. Didnt start again a day later, pulled fuel pump relay for 5 seconds, started right up. That trick didnt work before the distributor cap/rotor change. Happened once more a few days later, same quick fix and hasn’t happened since.
I just bought the 06 chevy silverado 4.3 with 119k miles and for 3 days it turned on fine. After sitting for 2 days it didn't turn on, crank but no start. I replaced wires, cap and rotor and now it starts now.
I have that similar symptom with my 97 blazer crank no start replaced My cap and rotor too and charged the battery and didn’t fire up right away, idk if it might be my fuel pump or some other type of fuel relay or electrical symptom but I let my truck sit and charged the battery up fully and it would run then after a few days would the same thing
Excellent video from the expert guy. However, I can't find it's necessary to check the TDC before you check the distributor condition. Then, based on the findings, you have to decide to check for TDC if firing is found ok.i.e means Timing Chain is broken?
1. I have owned many Chevy 4.3 motors. And my current one is a 97 Chev with 320,000 + mile on it. 1) Chevy 4.3 is a non interference motor. 2) There is no tensioner on the timing chain. On Honda and Toyota yes and other non domestic vehicles.
Ok I have a 2000 Chevy with 5.3 liter 4wd my truck did run now it will start up and then die like it looses fuel pressure got new fuel pump new plugs and wires online filter good switched fp relay all fusses good I'm stumped any advice when it was running seemed like I had to find sweet spot on gas pedal to make run better then when it goes to overdrive it's like I lose power slows down. Thanks
Brandon, if you have fixed the fuel pressure, it sounds like you may have a bad throttle position sensor[tps]. Either bad or out of adjustment. Adjusting is fairly easy, usually done with a torx screwdriver and volt meter. Hope that helps.
I have a 97 gmc 2500 I replaced fuel pump fuel filter fuel relay spark plugs distributor cap and rotor. I have pressure at the fuel rail. Car will not start. But if I spray carb cleaner it will start and run as long as I spray the carb cleaner. Does anyone have any advice?
PVC clogged cap & rotor has corrosion will make it rotate with miss at cranking ...Clogged PVC valve will send exhaust fumes into distributer and will change the cap rotor often !
I have a 2007 Chevy Silverado 4.3 it turns over know start know spark new coil new distributor module crank sen. Batt good fuel pressure new plug and wires had it the Chevy dealer ship they had it a week and called me to come pick it up they had know idea what the problem would be or where to start to look.it ran fine going down the road and it just cut off and hasn't ran since that's been about 2months ago. Any help would be greatly appreciated
I have a coil on my 4.3 vortec and with a new coil wire, and it's getting orange fire I've been told it's supposed to be blue can weak fire from a coil cause mine to not start?
I have a 2006 Silverado crew cab 5.3 and it cranks 1 time then starts at the 2nd crank runs and works good just dont know why it does that and then sometimes it starts first crank it has new ngk spark plugs and wires they told me it might be the fuel filter. Any one have the same issue?
Have the same problem with my 1992 5.7l. Checked tdc 5 times pulled the dist cap off each time. No visible breaks. Has spark and fuel. Should I try a new distributor?
i try starting my 00 5.7 vortec it cranks n wont start i turn fine about a week ago every week n now it only cranks has new spark plugs dist cap n rotor crank sensor also tested batt is good
I have a 96 Silverado honestly i dont know why i keep it. Aside i see others & theres run. Mine is broke more than running. Reason why. Computer. Have a 95. Runs great. 96. First yr for obd2. Unnecessary computer garbage making vehicles a nightmare to work on
well done sir , I have owned three S10 's for me it was always dis cap or rotor or distributor going out to lunch but then again they had over 300,000 km on them here in Alberta Canada , I still drive a 1991 GMC 1500 with a 5.7 and it still runs on propane and gas , love that old truck with 443,000 km on it , that clean propane kept that engine running . I was going to buy a new truck ,but it was cheaper to do body work them buy a new rat infested computer newer models that I cant work on for 90.000 $ . what she looks like now , th-cam.com/video/-BDUuHcDqW4/w-d-xo.html
And you’re annoying.. feel bad for anyone that has to deal with you being in their life.. Everything he said was informative, it’s not like he was rambling on about his diet and his uncle in prison or something.
Please post any other repairs you do to this engine. You're a good instructor and explain things easily.
Now this is how everyone else's "Repair Videos" should be like. He explained each and every step and the why's and why not's!
The beautiful sound when you turn the key after you figured it out. Awsome video 👍

@J G did you solve your issue brother?
Did it work? I replaced all the above and still won't start
@@cyborgslayer2552 same here no distributor new cap new pcm and no luck
Check your grounds 🎉🎉🎉🎉🎉🎉 mainly the one passenger side on engine block to the firewall clean connections and the truck will start

Was you getting the red battery on dash to@joeykanakanui4994
Great! Video hopefully this solves my issue.
My 2001 chevy express has a 5.7 and the number one cylinder is on the front drivers side of the engine.
A nice common sense video. Nice job.
my truck is doing the exact same thing. I will try the distributor first

0:20 your problem is someone stole the A/C!
On my 2006 Sierra I had crank but no start. It was the rotor.
Mine was a simple crankshaft position sensor. I also did a tune up and changed the fuel pump cause the truck almost has 200k
I did not see a spark when he sat the spark plug on the alternator. It was not sparking in the beginning.
Yes it was
1. I have owned many Chevy 4.3 motors. And my current one is a 97 Chev with 320,000 + mile on it.
1) Chevy 4.3 is a non interference motor.
2) There is no tensioner on the timing chain.
On Honda and Toyota yes and other non domestic vehicles.

@@nunyabizness9544 it has to be something in the fuel system. Maybe injectors?
@@wolfman6553 thanks I will check that out next time I go to riverside. The car is in a friend's backyard.
Thank you for sharing your tutorial and trouble shooting, may want to let him know may need brakes soon...
Great video I learned something new today, great job. Thinking a white ink marker would have worked better though.
Gary Taylor 96astro van no fire keep blowing fuse
Or you could use the factory one on number one cylinder!!!!
I replaced my distributer. Everything lined up #1tdc ran good for Aprox. 30 seconds, shut off ... Has'nt hit a lick since.???? Help
Same thing just happened to me. I’m currently on the side on the freeway watching this. New plugs, wires, cap & rotor and ignition coil.
Same any help
Sorry, If you drop the distributor back in the same location it doesn't matter anway.
I wish I had this knowledge. Thanks hammer and nail doesn't work on pickups
PVC clogged cap & rotor has corrosion will make it rotate with miss at cranking ...Clogged PVC valve will send exhaust fumes into distributer and will change the cap rotor often !
On my chevy caviler 2000 had no start but it crank has good pressure but has fuel on the plug but it will probably be the icm for the coils
Timing....chain jumped because it got loose....it was just needing replacement....because of many miles on the engine....
What was the problem? I've got a 2000 chevy s10 2.2l doing the same thing. I was thinking bad fuel pump I can't hear it kick on anymore either
My problem was the Cap and Rotor..
.but I did replace the ignition coil. And the fuel pump relay.... so.
I should be up and running soon...
That was the wrong cylinder to set to tdc. That was the number 2 hole
Great way of trouble shooting!
Crankshaft is in 2 pieces back will spin with starter front don't ???

Did you ever figure it out I have the same problems died out of nowhere replaced all the stuff you replaced and no luck
Same problem
@@sammiecribb7058check all the grounds coming from battery
Buy the billet distrubutor. It is a bit pricey. Otherwise you will have trouble with the stock distributor again.
Hmmm...WHY was the timing light firing away??
Why put cyl #2 at TDC???
What model truck was it?
I have the same problem sir,can you help? It cranks but dont start,it has spark and have fuel in the tank
I have Same problem 96 GMC sierra.
What was the issue
@J G did you ever figure it out? My truck keeps doing the same.
@@SuperBigdaddyjohn same here 4.3 died out of nowhere new distributor cap eveyrhing is aligned new crank sensor new ecm module still no luck
Any ideas?
Why did you put the #2 cylinder at tdc?Thanks
Good point.
I have a 2002 blazer that has a spark and has fuel through the injectors. However, the engine cranks but doesn't start. What could it be?
How much fuel though?
Perhaps your fuel pressure regulator ,clogged fuel filter is causing a pressure drop.
Possible Crankshaft sensor
Had to replace the distributor on a 98 GMC 4.3l, came apart inside, acted like a timing chain.
I replaced the whole distributor, plugs and wires cranks but still won't start. Any ideas? It has fuel, compression, and spark
Check your grounds
Did you figure it out? Mine is doing the exact same thing and replaced those 3
Thanks Alot
This is an awsome video, thanks alot
Did you pull any codes off this first??
Fine troubleshooting sir
Thank u so muvj
The belt is not lined up correctly. Its missing 3 teeth on lower pully.
need to show how to time engine not just put distributor in same position
I have a coil on my 4.3 vortec and with a new coil wire, and it's getting orange fire I've been told it's supposed to be blue can weak fire from a coil cause mine to not start?
Brandon Wilkinson. How you get it fix
@Chad Maus , Bad grounds & fusible links are a very real possibility. They can throw all sorts of random "ghost codes" .
what name is it?
I have a 2006 Silverado crew cab 5.3 and it cranks 1 time then starts at the 2nd crank runs and works good just dont know why it does that and then sometimes it starts first crank it has new ngk spark plugs and wires they told me it might be the fuel filter. Any one have the same issue?

Have the same problem with my 1992 5.7l. Checked tdc 5 times pulled the dist cap off each time. No visible breaks. Has spark and fuel. Should I try a new distributor?
check ignition switch, crank position sensor
Check maf
Ever figure if out? 98 gmc suburban, I replaced coil, ignition control module, distributor cap, rotor, Fuel pump, new spark plug wires crankshaft sensor, CRANK NO START!
Check your oil pressure.
@@martinwilkins8196 did you figure it out? Thanks
Hi i put a new fuel pump and after 10 min. It die and now it would crank but no start
See if you are low in oil.
Check your coil it happen
If you just replaced the fuel pump check the ground that bolts to frame rail its will have issues if you dont clean off the rust to bare metal
Sounds like might be cam/crank sensor
Who would turn crankshaft counter clockwise? Ain't that messing up the timing.
Nope
I have a 04 Silverado 4.3 my truck will not start I had just put a new distributor in there last year I am trying to see why it won't crank
Mine is doing the same thing what was the problem
my truck cranks for a while then it does start.then it starts shaking right after and white smoke comes out the muffler.any ideas what it might be?
Blown gasket
^^^ yup. Should have that sick sweet smell if antifreeze.
I am having that same problem, what was it?
Does anyone know what is supposed to be in the empty bracket shown in the beginning of the video?
