I have a built bottom end and boosted d16z6 in an eg hatch. walboro 255 FP. The car has been running fine for 2 years. Today I went to start it and the fuel pump is not priming. it was starting but would die, then it would start and idle but would die when I gave it gas.

I swapped the fuel pump and nothing, tried a known good main relay and nothing. My next thought is TPS but wanted some suggestions before I swap throttle bodies in a random store parking lot

Thanks in advance

Bad ECU... the fuel pump circuit may be damaged. Try another known good ECU... just to see if the car cranks and runs.
