Hello, So I swapped in the instrument panel in my 99 S10 with used unit. The PRND... had gone out. The new unit seems to work perfectly in every way but the truck will now not start. I get the solenoid click but that's all . Does not turn over all. The voltage meter reads no more than 10V but as I recall you never got he full 14V until the engine was actually running. So, before I re-install the old unit , Is there anything related to the instrument panel that would prevent the truck from starting. Where else can I look for problems. As I said I get solenoid click, instruments light up, engine does not even attempt to turn over. Thanks in Advance John

I think you need to check th e battery it should have about 12.5 V with no load and yes 14.3 after starting |

Iv got a 1984 chevy s-10 and when i turn the key nothing happens! the radio, heater, and windshield wipers don't work. I'v tested my battery and its fine and i put a new starter motor in a few months ago. Im thinking its an ignition problem..... any ideas for how i can fix this???

Replying to: cbowles (Sep 29, 2009 11:34 am) Don't have to much information on a 25 year old truck. The switch will power certain fuses, that is a good place to start, no power at your fuses then trace to where it should come from. All the ones you listed with no operation, are switch powered. |

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? |
