If so, then you are spot on if his test light lights when he turns on the ignition and the test light is on the fuel pump out circuit on his FP relay.
Well Thank ya'll Fuel pump issue solved turns out the relay was under the dash next to the 4.3 ECU there was a relay actually labeled with duck tape Fuel Relay
there was two Grey wires coming out 87 one was broken.
Reconnected it and starts right up. Fuel gauge and blinkers still not working and they were before this all started. I am thinking may have just fried the gauge when jumping the pump off the battery the first time. Or maybe the float is stuck gonna play with it more.
Guessing the blinkers is just by chance a diff issue that happened to happen at same time. Gonna mess with blinkers next if I cant figure them out should I start a new thread or just continue on this one?
anyways thanks again ya'll
P.S. anyone have a wire diagram well just for the 2 harness's coming off the ECU on a 93 Blazer. looks like this if that helps.
