Hello,
I have an inherited 89 mustang LX 5.0 that is cranking but not starting with the fuel relay not clicking and the pump not priming. I have tried bypassing at the EEC test with pretty much no success. The only thing I have been able to find is when the inertia switch is power probed the fuel relay clicks and the pump will prime. I have also noticed testing an injector with the key on or off are getting roughly .02 volts which seems very low. At this point I am thinking a hot wire is grounded somewhere as the probe is seeing ground almost all the way around the system even at the green 8 pin coming off the eec. I'm not exactly sure if I just need to keep chasing the red wire that runs that circuit or if anyone else has any suggestions?
