fuel problem
I recently was involved in an accident in my 1990 mustang gt the car was totaled but I was able to save the engine and trans.I purchased a 87 notch that already had wiring harness and eec from a mass air car,anyways after dropping my motor in it wont start the fuel pump is running and I changed the filter even put my gas tank in it.I can pour a lil gas in the throttle body and it will fire up til it burns the gas.It seems like the injectors arent firing but I checked the hot wire on the injectors with the key on its showing a steady hot and the ground checked out.I'm about to pull my hair out over this thing any help would be much appreciatted.

If the engine wasn't transplanted from a running vehicle, I'd say check the TFI/PIP. Since that isn't the case, you probably have a pinched wire in the injection harness from the motor swap.

There is a constant 12v positive to injectors with key on. The fuel pulse width is created by the ecm with negative pulse. Hook up a fuel pressure gauge. Use noid light for visual. Hear pump...crimped fuel line, plugges filter, hose above pump not clamped or split.
