Im trying to get my car working properly and I was double checking all of my wiring, and I noticed I did not splice anything to this wire. It is slot F and is Grey on the white 10 pin connector. Heres what I have.

FUEL PUMP RELAY (FPR)

FPR--tan -- tan/white(from fuel pump)
FPR--Blk/white -- ground
FPR --green/white -- green/white from white 10 pin
FPR--Orange-- power

That's what I have and it DOES NOT include the Slot F, grey wire, from the white 10 pin connector. If anyone knows if this is right or what the grey wire is for please let me know.

That would be incorrect. The wire you need for fuel the fuel pump will be green/white in the C220 (white) connector in slot J. In the 220 you should have the following

A) Red Generator Feed for the alternator (this is where the resistor should be spliced in)

B) Tan Oil pressure feed to the gauge
C) Brown Oil level feed to the cluster (if you have a check oil light)
F) Tan Serial data connector (maybe)
G) Dark Green/White VSS (goes to the Speedo)
H) Dark Blue (auto) performance switch sensor or White (manual) skip shift indicator (sorta cool to hook up to the shift light unless you program it out of the PCM)
J) Dark Green/White Fuel pump relay control (this is the wire you hook to the green/white wire of the existing FPR
K) Dark Green Temp sending unit to the temp gauge.

Yeah, that's the wire I used, I just typed it incorrectly. Sorry.

What year is the wiring harness you are refrencing? Because what I'm looking at, says "F" is grey and is fuel pump motor feed. Maybe my refrence is wrong and that's why my car wont start. Now, out of your list of wires, I have only wired the wires I thought were necessary to start and run the car. Which from what I could figure out, would be the J slot. That's the only wire I have currently spliced from that connector.

Don't forget there are 2 power wires to the PCM, a pink wire (switched power) in the C230 (blue) and an orange (constant) in the C100 connector of the LT1 harness.

RAGEman

Odd. Heres what I have for the C100 connector.

A) pink - power feed from injector fuse 9
B) dk grn/wht - A/C compressor relay control
C) dk grn - A/C compressor clutch solenoid feed
D) tan - serial data signal
E) brn - air pump relay control
F) brn - power from fans/SOLs fuse 6
G) pnk - power feed from ignition fuse 11
H) dk blu - secondary coolant fan relay control
J) grn - primary fan replay control
K) pnk - power feed from injector fuse 10

Thats what I have. Out of those wires used only the pnk wires. I wired them to the fuse box inside the car. Is this correct?

Klortho

There are pink power feed in the G connector of the C230 connector it is pink that goes to a switched source. There should be an orange in the C100 connector or possibly the smaller connector that goes to constant power. I would have to go look at mine and see which one mine is in. Mine is a '95 F-body harness which some of the wiring was different than what I saw.

I have checked all of my wiring and it appears to be correct. I am now thinking that I do not have the proper fuel pressure. I need to find my guage, and test my theory, but I believe I will do as you did (Klortho) and replace the FPR with a new one, and check to make sure the Pressure regulator is functioning properly. When I turn the key, it primes like it should but perhaps it's not keeping a good pressure. I dont know. I'll check it tommorow. To anybody new coming in on this thread, My car is cranking, starting and then runs like crap for a few seconds or more, (it varies), it runs like crap and dies.

Also, my brother has a 95 Z28 and I took his computer out and put it in my car, just to see if my computer was bad, and It didnt work, it did the same thing. I just thought I would throw that in for kicks and giggles. Any ideas are much appreciated. I miss my car.
