It will not stay running

[rstyrlz]

1991 S10 2.5L TBI Manual Transmission. Idles fine, drives for about 10 minutes and dies, restarts after about a 3 minute wait and dies again after 10 minute drive, basically it gets warm and dies , cools down & restarts, gets warm and dies. Code 13 is only code that comes up .Can a Code 13 shut down fuel pump? I can smell gas after it dies. O2 sensor was changed about a year ago

Blazer You never wrote back on my s-10 I was hoping to get your opinion. I have completed many tasks since you last wrote. I replaced the ECM and that has brought fire back to the truck. I now have fire and fuel when it broke down this time. The truck would not start after driving about three miles in 95 degree heat. I have replaced the fuel pump, ECM, FF, checked the timing but that did not go well as I could not keep it running when I lined up the timing marks. I read in the Haynes manual that there is something where you disconnect so the timing could be set but I could not verify that it applied to my motor and model as I could not find the brown wire with tan stripe to disconnect. It ran for those three miles like I have never heard it before and in mid driving on a slight decline it just died. any ideas what this could be? I am running out of money, patience and time as my son needs this to drive to school. HELP I did verify that both fuel and sprak were present and the starter motor would turn the motor but would not 'catch'

This was a note I sent to Blazer. I have a 4.3L V6 1991 2wd Pickup. I replaced the fuel filter, fuel pump, plugs, plug wires, distributor cap, rotor button, I measured both ignition and pickup coils, inspected the vaccum lines, verified voltage through the coils replaced the ECM as I had lost fire as well. My next guess is temperature driven components. Once I can save some money I intend to try the coolant temp sensor and the manifold air pressure sensor.

rstyrlz need to check your tps. in the manual it says to check for a sticking or misadjusted throttle position sensor, check the wiring and connection from oxygen sensor.

Thanx jackass#1

replacing o2 sensor will check TPS too

it was fuel pump wiring! wires at the top of fuel tank were corroded and broken causing a short to the pump . instead of replacing pump assembly and wiring I think I'll just rebuild truck & install a bigger tank .Will a 289cu in. fit ?
