Question about 2001 GMC Jimmy

1 Answer

So my truck started and then shut off while driving...distributor cap has been replaced and it still runs but then then back fires and drives at 25mls per hour, white smoke starts poring out of the gas tank and rear driver side tale light. I am thinking it's the fuel filter because there fuel pressure has been checked and is about 60 pounds, the correct amount. Still turns on occasionally but then shuts off again. Checked battery, spark plugs and distributor cap has been changed. If anyone knows whats going on please please help...i am female and running out of options.

I have a 1999 Chevy Silverado 4.3L V6 that sometimes starts. I have fuel and fire. When it starts it runs perfect. What is wrong? I have changed crank sensor, ICM, distributor cap and rotor. It will s


Things to check. The pick up coil in the distributor, this can be tested, by the test is not always accurate. Next , you have to pull the distributor out of the engine and check the drive gear on the bottom. On the older 4.3 engines, anything to do with ignition, the first thing I do is pull the distributor. I have replaced a lot of these gears..They just wear out. You'll see it by the thickness of the gear.

My 99 chevy blazer 4x4 misses and shuts off some times back fires through the exhaust


Usually, an engine that backfires thru the exhaust is a sign of ignition problems.
Assuming you have the standard 4.3 V6, you should have a flat distributor cap and standard rotor.
I would start there.
The cap could be shorting out inside and making the coil fire the wrong plugs at the wrong time.
It could also be other issues with the distributor or the ign module.
