Wiring and everything in that aspect is supposedly complete got the car on trade a week ago been slowly going through and figuring out what I can with my basic knowledge, today figured out I have no injector pulse or power to the injector whatsoever
Originally yes although 2 owners back it was swapped with an 88 turbocoupe motor and transmissionIs this a 4 cyl car?
Good to know with Haynes not being that great of a wiring manual, im digging in again today, ripping off the cold side of the engine and like you had advised start tracing back injector by injector as it shouldn't be an ecm issue, none of the pathways diodes or anything internally looked damaged meaning its more than likely wiring somewhereHaynes = garbage! The factory wiring diagram I linked to covers every circuit in your specific car. It shows paths, connectors, colors and even has whole car vacuum diagrams. It's what Ford techs used at the dealerships before it all went digital. The EVTM's are pretty detailed also.

Here's a step-by-step wiring conversion for an '88 LA2/3 into a '90 Mustang.
I did the conversion when I built Thunderstang.
Unfortunately, about 5 years later some clown rearended me and totalled the car.........
However, I was able to pull the motor/trans and dropped it into my '27 roadster so.........Thunderstang lives on!
