I've got a 94 GT. One day it was running fine and a few hours later it did not want to start. It just cranks and cranks.
I went to a buddies house to take some parts off his 95 Cobra (it was running) to test on mine, so i wouldn't have to buy any parts. I swapped out the dizzy, coil, and icm and none of this worked.
I show 39lbs of fuel on my fuel rail gauge.
When I swapped the dizzy, i set the timing wrong and I had a large backfire (sounded like a shotgun). Re-stabbed the dizzy and timing is correct and no more backfire.
I then went on to see if I could hear the pump. Unfortunetly, I got a TREPerformance 255 pump and those are super quite. I only hear the clicking of the relays but not sure if I can hear the pump prime. I then proceeded to check voltage at the ccrm and inertia switch.
The input side of the inertia switch (DGN/YLW) shows 9.7 volts (likely cause of my battery discharging from all the cranking and no charging). The output side (while connected to the switch) shows 0 volts. I proceeded to pull the connector and bypass the switch. After jumping the input and ouput of the connector, I no longer get voltage on either side. If I remove the jumper from the output side, I get 9.7 volts again on the input side.
Is this signs of a bad ground somewhere? or maybe the pump? The diagram I have shows that there are 2 wires to the pump. A PNK/BLK that converts to BRN/PNK and goes to the inertia switch and a GND wire.
Am I missing something? I also swapped out the CCRM but still nothing.
