I've had an 01 xtreme w/4.3 vortec for 2 days and it left me on the side of the road on the first. Ran fine then it died doing 50mph. Did not restart until next morning. Already changed coil and ignition module. Seem to have good fuel pressure. Checked all the relays and fuses, they test ok. Any help is greatly appreciated.

Sounds like the fuel pump to me.Put a pressure gage on the fuel line and try to start it.It should read 50 to 65 lbs of pressure.If that checks ok change the fuel filter.If it still wont start,I would use a timing light to make sure it hasnt jumped out of time.Good luck.

pressure gage should read 50 to 65 lbs.30 lbs isn'nt enough.If that checks ok i would have an obd scanner hooked up to it to pin point the problem.

Watching this forum is almost as frustrating as trying to fix my S10 was. See message #133 those of you who are changing everything and still having your mystery problems. Most sound like a lot of what I was experiencing. It seems to me that rigging one simple jumper wire to check is cheap and easy, even if you have to look somewhere else for your year's feed to the computer. But nobody seems to have written about trying it -- worked for me is all I can say. My truck is still going strong ... all mysteries have disappeared. Maybe nobody writes about successes, maybe this hasn't worked for anyone else. Good luck.

All you needed to do was remove the wire off the starter and clean and reinstall.

93 S-10 2.8 V6 Idle problem by green0886
Dec 04, 2008 (4:23 am)

I have a 1993 2.8L V6 S-10. This is a 2wd truck with 172000 on it and no problems till now. The problem I have is when I first crank it in the morning it idles like it has a huge cam in it. After the truck warms up it idles high for about the first 30 min of the trip then returns to regular idle with no other problems. I have read the check engine light code and it says "EGR Failure". The EGR has been removed cleaned and the bellow check for correct operation. Plugs, plug wires, distributor cap, rotor button and throttle postioning sensor have been replaced with it the last 4 months.
Any help or comments on this would be greatly appreciated....

difficult first startup of day by bobpomeroy

It won't start w/out a lot of pumping and retries. It seems like something is not telling it to inject fuel for starting. It is not flooding. Once it starts, its fine for the rest of the day until starting the first time the next day. It's a 2002 s10 v6, and a honey otherwise.
