Replying to: pat_chevy15 (Nov 16, 2008 1:52 pm) 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.

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. Replies to this message: gonogo (Nov 19, 2008 8:12 am) mickey_m3 (Oct 20, 2009 7:18 pm)

Replying to: plaiddreams (Nov 18, 2008 9:08 pm) All you needed to do was remove the wire off the starter and clean and reinstall.
#151 of 195 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....
#152 of 195 difficult first startup of day by bobpomeroy Dec 04, 2008 (1:44 pm)
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.

#155 of 195 same problem by bobpomeroy Dec 14, 2008 (4:10 pm)
but mine eventually fires. I think it has a bad sensor, but haven't gotten around to changing them. If your engine is computer driven, I think that's where you're heading eventually.
