92 GT 5.0-EFI,EEC-IV System,38LBS fuel pressure,coil good,new cap ,new rotor,good plugs good spark to plugs,new ign module,new crank position sensor, fuel injectors not pulsing. Did test injector harness with light node.

 

My 94 Gt 5.0 was going through a spell where it would not pulse the injectors. I had a guy from a Ford Dealership look at the car and he said it was either the ground wires by the battery or the ecu was going bad. I took off the ground wires and cleaned them and I still had the same problem. I'm in the process of changing the ecu with a new one. If you have not also seen this thread check it out as well about a car not starting. Hope this helps.
