Replying to: lesahudson (Feb 11, 2008 9:11 am) Sounds like a classic coil problem. Check to see if you are getting spark when the engine dies.

How much does it cost for a new starter for my vehicle?
#139 of 215 Fuel System Problems by bcarpenter Mar 07, 2008 (11:16 pm)
I just had the starter replaced on my 1993 Blazer, but she is still having a problem starting. It has a 4.3 L V6 Vortec with 191,000 miles. I've been told it could be build up in the injectors, but I've also been told it could be a compression problem. When I start it after sitting overnight I have to spray carburetor cleaner in the intake valve for it to fire. After that it's fine unless it sits longer that 30 - 45 minutes. After that time frame the whole spray to fire process starts again. Can anybody tell me what this problem is so I don't spend a fortune on pointless work and carburetor cleaner???!!!
#141 of 215 1992 S-10 Blazer won't start all the time by sheps47 Mar 30, 2008 (4:30 pm)
I have a 92 S-10 Blazer with a 4.3L. It starts fine most of the time, but every once in awhile it won't start. It acts like the battery is dying. After waiting 10 minutes it will start up fine (without charging the battery). It does it whether or not I've charged the battery or not. Please help.

Replying to: sheps47 (Mar 30, 2008 4:30 pm) Could be an intermittent cell in the battery. How old is the battery, and have you checked the voltage on the battery when this occurs? Are the battery terminals clean?   Easy trick: when the engine won't start, turn on the head lights. If they are dim, you either have a bad battery or connection, probably also at the battery. If they are bright, but dim noticeably when you try to start the car, same thing, either battery or connections.

Replying to: jlflemmons (Mar 31, 2008 5:29 am) I think the battery is pretty old. It has been drained completely twice when the dome light was left on accidentally. The voltage is around 14 when it is running. Thanks for the help. I'll check the headlights and see if the battery is the problem. Thanks!!!

Replying to: sheps47 (Mar 31, 2008 5:48 am) Well, if you are seeing 14vdc with the engine running, you know your alternator is working! Replies to this message: blazergirl96 (Mar 31, 2008 9:12 pm) jlflemmons (Apr 01, 2008 7:31 am)

Replying to: jlflemmons (Mar 31, 2008 7:24 pm) My '96 would turn over good and only start intermittently...it was the COIL! It was arcing and grounding out to the engine. Would turn over, but no fire! Replace coil and wire and problem all fixed!! It took us replacing all kinds of parts relating to the ignition to find this out!! CHECK YOUR COIL!! If it sparks like a christmas tree...it's no good!! Replies to this message: jlflemmons (Apr 01, 2008 7:31 am)

Replying to: blazergirl96 (Mar 31, 2008 9:12 pm) Good point. Easy trick is if the car will start, mist water onto the coil and wires. Can get exciting to watch at night, but will tell if the insulation is breaking down. Since you identified this as your problem, I have had a GM mechanic tell me this is a common problem on the 4.3L because the coil wire tends to rub up against a bracket between the coil and distributor cap.
