I've had my 96 S10 since 96. It stopped starting without manual injection of starting fluid. Runs fine once its going. I don't hear the same fuel pump sound at start up. In message 133 someone taked about installing a jumper wire from battery to junction box next to heater on firewall. They said the little trouble light wire runs to this junction. On my truck I can't find the junction box. There is a black plastic covering on the sidewll near the power brake booster and anti lock brake unit. it has four bolts for wire connections some of which have heavy duty red wires connected. According to the 133 message a wire that comes up from a sensor at the oil pan (or starter?) that feeds power through the dash to the computer commonly corrodes. He said easy fix, but if I wanted to leave the jumper wire in - put in a 60 or 80 amp fuse as charging circuit was involved. I live half mile from ocean so things could get corroded. I heard that a fuel pressure of 30 lbs or less was bad. Would low pressure prevent an engine start? Good pressure is 50-65 lb. However, I don't smell fuel in the intake after turning key to start without pumping gas pedel which indicates fuel pump is not being told to pump at start up. I also read from another message 108 that if the TPS is bad it won't signal the ECM that it needs fuel as it is telling it that it is not starting. What is a TPS? I've replaced the inexpensive - plugs, plug wires, fuel pump relay, and checked fuses. I don't want to replace fuel pump or coil or distributor or ECM or injectors until I get better intel. Reliability report at MSN Autos for 1996 S10 says common problem on this vehicle are failures of the fuel pump, fuel injectors and EGR valve passages. Failure of the fuel pump and fuel injectors may prevent the vehicle from starting. The cost to repair the fuel pump is est 250 parts 130 labor. The cost to repair the fuel injectors is est 95 parts 195 labor. The cost to repair the EGR passages is 16 parts 58 labor. I have 150K miles without tuneup and never used a fuel injector cleaner solution in gas. I've read there are a number of sensors that can tell whether the engine is hot or cold which if messed up could cause a similar no start problem. However, my problem persists hot or cold. I can restart without starting fluid if done within about 15 minutes of a shut off. Some gas must not have evaporated yet. The check engine light goes on and stays on for a week or two then goes off for months. I never had the code checked. Has anyone fixed this problem for good and how? |

Replying to: plaiddreams (Nov 18, 2008 9:08 pm) We were searching possible problems for our 2002 S10 4.3 as it began with misfire and he replaced the Spider Injection (brand new), complete tune up and truck has good fuel pressure 65 lbs. at idle. Nothing is working and were are at lost. The truck runs, however random misfiring at cyl. 3 and will not rev up. We came across your post and noticed that you a lot of made sense. Any help is greatly appreciated. |

I am searching possible problems for our 2002 S10 4.3 as it began with misfire and he replaced the Spider Injection (brand new), complete tune up, replaced distributor, crank / cam sensor, coil module and truck has good fuel pressure 65 lbs. at idle. Nothing is working and were are at lost. The truck runs, however random misfiring at cyl. 3 and will not rev up. We just bought the truck used and only able to use for 1 week. We have dropped over $1000 in repairs and he wants to junk but I wanted to see if there was any saviour for it. Any help is greatly appreciated.

I recently bought a 2000 s-10 2.2L manual transmission. It stopped starting only 3 weeks in. I cursed it up and down for two days trying to trace the problem. The order of events began one evening when it took a while to turn over. I cranked it three or four times and finally got it to turn over. The next morning was a different story. It tried to turn over for a while and finally stopped cranking. Long story short I cleaned the starter and the wires running to that, and at least after that it tried cranking again. Finally a mechanic friend got his hands on it. Seems the fuel filter was shot, which i hear is common, and he replaced that, but with no change in status. He was about to drop the tank and remove the fuel pump when he first decided to test all the wires running to the pump. I understand this is a miserable process. At any rate, they all tested ok, but somehow after detaching and reattaching, the fuel pump came on and started working properly. He hypothesized that resistance built up and the pump overheated. Whether this is right or not, the truck now runs. So, try undoing all your fuel pump wires and reattaching them. May just work for you too.
