#24 of 195 RE:93 S-10 won't start when rains [hoodlatch] by joec10 Jan 23, 2007 (1:02 am)
Replying to: hoodlatch (Jan 22, 2007 6:27 pm) I will go over all the vacuum lines once the weather warms up--I have a 2001 s-10 but I garaged it during winter and drove the 93. I will keep that tip in mind--thanks for the information..

After changing the distibutor module, I still wasn't getting spark to my coil..I had to replace the pick-up coil in the distributor and the truck is back on the road again..

#27 of 195 2000 Sonoma will not start at 1/2 tank of fuel by mikeg11 Dec 07, 2006 (7:25 am)
My 00 Sonoma will not start when the tank goes to 1/2. I can drive it, but it will not start up. When I fill it up it only takes about 10 gal, letting me know that the sender is ok.   I havent changed the fuel filter at all in 81K mi.   The truck is a flex fuel E85 model, but only run regular gasoline. Where should I start? Could low fuel PSI cause this problem? Thanks! Replies to this message: canufixit (Feb 15, 2007 9:46 am)

Replying to: mikeg11 (Dec 07, 2006 7:25 am) Interesting ....   Ok here is an off the wall thought.    Will it Start when the tank is Below 1/2 full ??? I'm wondering if the pick up tube in the tank has a very tiny hole in it... once the fuel gets below the line it starts to suck air. If running it may just send some small amount of air into the gas system. If the engine/fuel pump stops - the fuel eventuall leaks our of the suction hole and when re- started, the pump can not suck fuel (Lost it's prime)...   Let us know what the solution is when you find it ...

I cannot for the life of me find the starter in my 2000 Chevy S-10 its an automatic with a 2.2 Liter engine. We were told it was behind the passenger front tire but after looking top and bottom we wern't able to find it. I have my replacement Starter already but I havn't had to deal wiht the starter before. can you help me figure out where it is?

Replying to: adrian10 (May 11, 2007 11:14 am) Similar problem, not solved yet. And it happened once last year (this truck sits a lot) that it would not start, and then worked days later for no apparent reason. 1990 S10 4x4 4.3litre. Turned key on ... fuel pump ran. Engaged starter, engine turned fine, didn't catch. Turned key off and back on ... fuel pump ran. Hit gas pedal, turned engine over ... engine ran well for about 3 seconds then stopped dead. Turned key off and back on ... no fuel pump running. Connected a jumper straight to the fuel pump ... pump ran. Turned engine over ... no run. Added ether ... it ran as long as the ether lasted. With jumper, checked gas pressure at tank outlet (good), and at throttle body (good). Changed air valve assembly (with injectors) for a spare ... no difference, and engine still runs fine on ether. It seems that the fuel pump and the injectors are not getting any electricity. Is there a particular sensor that would govern that? Would that kind of sensor show up on a code reader? Thanks.

I had the similar problem, started last may, tried to fix since this without results but yesterday, I tried a new distributor module ... looks like it solved the problem !! I will tried to start it for a certain period to verify that, even cold starting than hot starting, but it seems to be ok !!! Replies to this message: bobpomeroy (Nov 29, 2007 7:42 pm)
#32 of 195 97 Sonoma V6 Won't Start in the morining (sometimes) by nitrate Oct 10, 2007 (4:32 pm)
I have a 1997 GMC Sonoma with the 4.3L Vortec V6. Owned it for about two years with no problems (180 000kms). About 2 months ago, I went to start it in the morning to go to work and it wouldn't go. It would turn over but not start. After about half an hour of screwing around, adding starter fluid etc., it finally went. Ran rough for a few minutes, but then fine all day. Replaced all the filters that night as they were due to be changed. A few days later, same thing. No starter fluid this time, just alternated holding it floored and not, took about 10 minutes to start, ran rough for a while then fine. Replaced plugs, wires, cap and rotor. Ran fine for a week or so, then problem returned. This time I couldn't get it to go to save my life. I thought because it only happens in the morning that maybe condensation was the problem (it starts after sitting all day at work and it had rained heavily the night before). Checked all the electrical connections I could easily access and they all looked clean and dry. Plugged in the block heater and ran a hair drier on the distributor for half an hour, then it started first crank and ran great. Next time it happens I will only use the block heater and see if that works. Any ideas? It seems to me some sensor is telling it not to fire, but not sure.
