hello everyone,
Im new to the forum and need some help.
94 4.0 5 speed 4x4 fuel pump issues
new pump(working and tested with 12v)
new filter
was driving fine but started cutting out on a hill climb, found the starter wire shorted on the exhaust manifold
getting 12v at pump with key on but wont run pump
getting good ground at pump(tested continuity and no resistance)
getting 12v at inertia switch
inertia is bypassed
changed out fuel pump relay and the diode
when i jump the relay the fuel pump runs
any ideas? thanks
