Question about 1996 Chevrolet Blazer

1 Answer

Chevy S10 starts and then shuts off.

I have a 1999, chevy S10 with 60500 miles on it, while driving the truck it stopped running and after waiting awhile it started but would not continue to run. Checked to make sure the fuel pump was still working had alot of pressure on the fuel port, and made sure that it was still firing and it seems that the engine has both. Tried to start today and it started after a few trys but would not continue to run after a few minutes. What is the fuel pressure suppose to be, friend said that they had alot of problems with the wiring harness on this truck and that it would get corrision on the contacts between the fuel pump and harness, and will not continue to maintain the pressure while starting. how can I check the fuel pump and module on this thing. seem like it is getting not enough fuel to stay running and help would be appreciated.

Thanks

    I have the same problem, it will turn over but quickly die..I changed the fule filter and spark plugs..I am assuming fuel pump..but have no idea...

    Run time gets shorter and shorter with each start. Running with starting fluid seems to me to be a fuel but not sure if the fuel pump is getting a shut-off signal, have a security light but no chip in the key. HELP!!!!

Well i would try squirting fuel into the throttle body when it is in its not running mode. if it starts and runs you know the fuel pump is at fault .. or its not getting the right fuel pressure from it..

My 95 chevy s10 pickup truck stop moving after 1/2 mile, after 5 minutes, it moves again, what causes the transmission to do this?


Front transmission pump.For a Chevy S10 its located behind the torque convertor,This pump supplies the torque convertor and it service as a pressure supply system, Just because the pump is in the immediate area it does wear out and develops gaps and is unable to supply transmission fluid to the system. When the transmission warms up the fluid thins out.Sitting for 5 minutes allow the fluid to cool just enough to run again
P.sthis remind me of what happen to me I stuck on the side of the road ,half mile and took 2 hours to drive back

My Chevy S10 will shut down, starts back up minutes later


Check if your wires are on TIGHTLY on the battery, if one loses a touch, your car will shut off. If you go over a tiny bump, or turn to one side or another, they could disconnect, causing your car to lose a + or a - cable connection. Which would very well make your car shut off. Also, check for any corrosion on the battery terminals. Good luck.
