I just installed a new fuel pump and fuel pump relay and the car still does not prime or start. I have gone through the Fuel Pump Troubleshooting Guide(thank you jrichker!) and got some answers but I was wondering if anyone else has had this issue and can maybe shed some light on the subject.
My car is a 92LX Convertible with 90K on it and is stock except a K&N Filter. In the first test, I have 5.7Volts going to the fuel pump. The inertia switch is not tripped and has 11.5V going to both sides of the switch. Next, the Fuel Pump Relay (this is where it gets a little confusing). The checklist reads that there should be a black/pink wire that is always “hot.” I have located the FP Relay and know it is not the WOT A/C Relay, however the black wire that I have is black with a thin yellow stripe. Is this normal—I cannot spot a Blk/Pink wire anywhere? In any case, that wire has 0 Volts going to it and the Red wire has 12V going to it.
Based on this information and the Troubleshooting Guide, is it correct to think that the black wire and/or fuse link are bad? I cannot locate where the black wire ends or the fuse link—I think it is at the solenoid. Anyone have any issues like this or can offer advice? Are my Voltage numbers correct? This has dragged out for a couple months and I am starting to feel in above my head. Worst case and I cannot fix this, I am located in Champaign, IL if anyone knows of a shop that is good, reliable, and knows the ins and outs of Fox Body Mustangs. Thank you in advance for your help.
