94 ford f150 5.0 fuse 9 (pcm) and pcm relay popping
I have a 94 ford f150 with the 5.0 in it and it
keeps popping the pcm fuse underhood
and and burn out the relay then stalls out
and wont start unless replaced and it has a
new computer also replaced the
transmission connector that the wires were
stripped on new iac valve new tps
The PCM is an electronic device very susceptible to overload, even a small one. The blown fuse and burning out of the relay would seem to indicate a short or excessive voltage being applied through the circuit. You'll need a wiring diagram unique to your vehicle and specifications for output voltage/ground/ testing procedures.
Pcm was burnt on the inside
Tha ks for thwe not helpful advise thank you for telling me exactly what i knew
