#19 of 195 85 S10 wont start by adrian10 May 11, 2007 (11:14 am)
Went to start my S10 several weeks ago after a few mths sit up. Stearted then died I quickly tried to restart and didn't here the fuel pump make it's usual pre start noise. Looked for a fuse blown. Checked them all (didn't know if the fuel pump had one or where it was) All looked good. Replaced the fuel pump nothing. Today I bought a fuel pump relay nothing. Anybody ever have this problem or know a fix?? Charged the battery turns over good but no fuel 1985 S10 PU 2.5 FI Thamks Replies to this message: plaiddreams (Jul 30, 2007 10:04 am)

My S-10 died again on another rainy day and would not restart..I changed distributor cap,plug wires,rotor cap,distributor module.It started, but I had a high pitch whine(sounded like a vacuum leak)..the truck ran for 3-4 minutes with the whining sound than it died again and I am back to square on..Any ideas of where to look next?????? truck is 6cyl, 4.3 runs great up till now..

Replying to: s1089 (Jan 21, 2007 10:15 pm) I had a vacumme leak on my V6 one time that I found by accident. There was a hard rubber boot in front of the air valve body that was cracked on the bottom. It had a 1/4 in. vacuume line coming off of it. After I fixed that, it ran great. Good luck,   Replies to this message: 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..
#25 of 195 S-10 wouldn't start in wet weather by joec10 Jan 27, 2007 (7:47 pm)
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..
#26 of 195 2000 Sonoma will not start at 1/2 tank of fuel by mikeg11 Feb 15, 2007 (9:46 am)
#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 ...
