fuel pump/wiring issue
I was sitting in traffic for nearly an hour when the car just died. No spitting no sputtering it just died.
When I key on I can not hear the fuel pump turn on.
Checked all fuses and they are good
I have a racetronics harness.
I have the car on jack stands and I'm testing for power. I have power to the harness from alt and that is good. I unplug the stock harness plug from the pigtail and test that, key on test light turns on for a millisecond then instantly shuts off, this should be staying on once key is on correct? Any suggestions?
How can I test the pump?
Where does the stock harness plug go?
From what I can see there are 4 fuses, 2 under hood and 2 in the footwell, are there any I'm missing?
Where are the stock relays?

The fuse box can get very HOT under extreme conditions. The fuel pump relay works hard and the output contacts could have overheated and starved the pump for current/voltage.
If were me, I would get a new relay and monitor fuse box temps.

i ended up figuring out what the problem was.... i found a "homemade" connector one of the shops i brought the car to from the racetronixs harness to the stock fuel pump wire, seems they soldered the contacts and the joints were broken. im going to replace the homemade connector with some good weather tight connectors and be on my way.
