    No Pink/black Wire On Fuel Pump Relay

    Yes. I was starting to think it must be the pump.

    No Pink/black Wire On Fuel Pump Relay

    Power at the pink/blk wire goes away with switch off. All voltages before and after the power connector are what they should be.

    No Pink/black Wire On Fuel Pump Relay

    I don't have another relay to swap in. I'll have to wait until Sunday or Monday to check the voltage and ground.

    No Pink/black Wire On Fuel Pump Relay

    Something else to consider. There is 12v AT the pink/blk wire in the trunk, before it goes through the floor. Does that make any sense? Also, the car ran at one point the way it is before I acquired it. My brother said it just died one day. Thank you for your patience and time with all...

    No Pink/black Wire On Fuel Pump Relay

    After stripping some loom off at the fuel pump relay, I found that the org/blk wire I spoke of looks wht/blk (weird how it could be so different). But bottom line is, it serves the same function as pnk/blk, so I'll call it pnk/blk from here on out, since all the other colors at the relay match...

    No Pink/black Wire On Fuel Pump Relay

    As much as I stare at those diagrams, it still comes down to me trying to trace the actual path of the wires on the car. For example, now that I know the red wire is the one I need to follow, how do I know where it goes next? Which connector does it end up at? I just need diagrams of what...

    No Pink/black Wire On Fuel Pump Relay

    Nothing seems missing at the relay. Org/blk wire has power before the key is turned on, then when I turn the key on, it opens the relay which sends power through the red wire. So I need to find out where the red wire goes. But since my harnesses are from different years, I would need some...

    No Pink/black Wire On Fuel Pump Relay

    So, in my case, the org/blk wire has the constant power source. Then the relay receives it's signal when the key is turned to the "run" position, which lets power continue to the red wire.

    No Pink/black Wire On Fuel Pump Relay

    I thought I did. Constant power should be coming to the relay. Then it needs a switched source to "open" the relay so the power can continue to it's destination. Am I wrong?

    No Pink/black Wire On Fuel Pump Relay

    So I jumpered the grn/ylw wire to ground. You said one of the "remaining heavy gauge wires" should have 12v. Meaning "either the org/blk, or red wire", or did you mean the "last wire left"? Just trying to clear it up because "the last wire (blu/org)" just isn't as heavy of a gauge as the...

    No Pink/black Wire On Fuel Pump Relay

    Org/blk has power with the key off. With the key on, the org/blk and red wires have power.

    No Pink/black Wire On Fuel Pump Relay

    Here's the relay under the seat. Key off=no power at any wire Key on= only pnk/blk has 1.8 volts, the others have none.

    No Pink/black Wire On Fuel Pump Relay

    This is the other relay next to the last one. Org/blk, Red, Blu/org, and grn/ylw. Update.... Key off= org/blk has 12 volts. Others have nothing Key on= grn/ylw has 4 volts, org/blk still has 12, red now has 12, and the blu/org has .05 volts.

    No Pink/black Wire On Fuel Pump Relay

    Here's one relay in the engine bay. You can see the other one behind it. I'll post that one next. This one looks to have a red, blk/ylw, org/ blu, and my daughter says the other looks org/ylw. Update... Key off=none of these have power Key on= red has 12 volts. Other 3 have .15, .01, and .01

    No Pink/black Wire On Fuel Pump Relay

    back when I first realized that the relay was under the seat, I tested it then for power, and had nothing. I could check it again just in case I missed something, like not having the key on or something.I do know, at the relay in the engine bay, that with the key off, no wires have power, but...

    No Pink/black Wire On Fuel Pump Relay

    Yes, there is a relay also under the seat. And the car is a 90. I also know that's a year all by itself when it comes to harnesses. I'm just trying to confirm why there's no pink/black wire at the relay. I'm really not looking forward to dropping hundreds of dollars for another harness...

    No Pink/black Wire On Fuel Pump Relay

    Thanks J, but being color blind isn't as bad as some people seem to think. It's not all black and white. And I have been looking at those diagrams for quite some time from some of your previous posts, and as you can see, there's a pink/black wire on the fuel pump relay no matter which one you...

    No Pink/black Wire On Fuel Pump Relay

    I'm pretty sure my fuel pump relay should have a pink wire with black stripe on it. The harness is from a 93. But the wires on the relay are red, green/yellow, orange/black, and another one that looks green/yellow, but I'm color blind, so hopefully my common sense has the colors pretty close...

    93 V8 Swap Into 90 4 Cyl. Wiring Harness Help

    TTT. I'm also reading that the wrong O2 harness could do damage. Is the O2 harness a seperate harness from the others?
