Not sure if this applies to everyone With an ECCS/Fuel Pump problem but wont hurt to check out
BACK GROUND: (Optional to Read)
(Wiring harness conversion done by Yury @ Wiring Specialties)
So i was having an Issue with my PFC resetting itself while I was driving and it got so bad that PFC Commander would not start up past the Start up Screen.
Reinstalled the Stock ECU and parts and the car would run like a champ.
I thought it was the PFC so i sent it off to Apexi and after $170 Got it back and now the PFC wouldnt even boot up
....
I could Jump the ECCS (EGI Relay) and the PFC would boot up.....
THE Problem:
Started checking the Brown plug since I saw this nastiness (as well as it having the ECCS wire)
Pulled out my Handy dandy Wiring schematic and start tracing wires
luckily the first wire I started with turned out to be the culprit, ECU Pin 4 to the Brown plug next to the battery tray Red/Black wire.
I got continuity to the plug but when testing after the plug on the Chassis side I not NO continuity. Gave a little Tug on the wire and it popped right out.
The wire had corroded and broke in half at the connector pin
More than likely due to letting the plugs hang outside of the engine bay exposing them to the elements and having crappy 20 year old seals
THE FIX:
Went and snagged another plug from an extra harness, Cut, Soldered, and Heat shrinked and now runs like a champ!!
