I had one in my c10 and it was noisy. I read somewhere that they are better pusher pumps then puller pumps. At the time I had my fuel system set up where it wassnt able to gravity feed the pump. Got a different fuel cell and it was gravity feeding and that helped with some noise .also didn't run a filter pre pump. Just Ran a 100 micron filter after the pump.

It's sucking air somewhere or maybe your low on fuel? I noticed when my truck got lower it would whine more when stopping or turning. It always did that but it never stopped working.

Hahaha. Glad you got it figured out. It's always something simple.

it has seemed to me that the engine harness and the lights/etc are on the same harness on my 99. did you just strip those other connectors out of the harness as a whole? ive been worried ill lose the power windows/locks when removing the ECU and other bits until i get to the point where i am gutting those components it would be nice if they worked.

I'm pretty sure the 99-04 are all wired (mostly) the same. There's a separate engine harness that disconnects at the back of the firewall on the passenger side. There are 3 or 4 connections that all unplug from the car. I think one is transmission as well. I unplugged mine from there and everything else in the car works fine. Power windows, locks, trunk release etc etc...

There's a decent amount of stock engine stuff intertwined with the factory wiring harness, but you can get away with removing almost all of it. Kind of depends on how ambitious you want to be. In my case, I started with a 3.8L manual transmission car, and I went with aftermarket gauges. I was able to delete the stock ECU and the CCRM (passenger's front fender) with only a few hours' worth of work; I vaguely remember having to short two wires together to get the clutch safety switch working so I could start the car, but that was about it. I later went back and was able to remove a lot more stuff from the harness:

1. In the back, you've got the entire fuel pump harness, which includes the fuel tank pressure sensor, misc. other evaporative emissions stuff, and the fuel pump driver module (99-04 cars use an ECU-controlled returnless fuel system). Since I was using two GSS342s in a full return system, I deleted all of this and chased the wires back out of the trunk, down the driver's side floorboard, across the cabin, and into what was left of the factory ECU harness.
2. There is a good bit of wiring that goes behind the dashboard from the stock ECU to to the stock gauges, and some other stuff. Don't need most of that.
3. Some more ECU-controlled stuff goes between the passenger compartment and the relay box in the driver's side of the engine compartment. Not needed.
4. There is wiring that goes across the front of the car from the relay box. I think part of this may be related to the stock fans, and I suspect that there is more related to AC and other systems. I'd deleted the AC a long time ago and had run alternate wiring for my fan setup, so I was able to delete this.

Ford definitely ran some stuff related to the passenger's side headlight and turn signal through one of the three wiring harness connectors near the stock ECU, so if you're deleting that stuff, you'll need to find and reconnect those wires. It's not that hard. The rest (except for the clutch safety on a manual transmission car, as I mentioned above) can simply be removed.

That's really funny you say that because that's the only thing on my car that doesn't work. My passenger parking light and turn signal acts as if it doesn't have power. I left everything ford in my car so I just assumed I missed a ground somewhere. You wouldn't happen to know which wires need to get hooked together do you? That would be very helpful.

lemming104

I don't remember offhand because I did all that stuff over a year ago, and I kind of did guess-and-test as I went. All I know is that there are 2-3 wires that are actually from the turn signal and parking light, they go through one of the three big connectors that are clipped on to the back side of the ECU in the passenger's side footwell, through the passenger's side fender grommet, past the CCRM (I don't think they go through the CCRM), to the passenger's side headlight.

Since those are the only two wires left that go through that wiring harness on my '03 V6, I can go in there and tell you what the wire colors are if that would help in any way, but there are probably over 100 pins between those three connectors, so I'm not sure how helpful that would be?

If you've messed around in there and/or disconnected the three connectors near the ECU, it is almost certainly that.

I literally unhooked the harnesses from the engine bay and installed my motor. Initially I was going to run the ford pcm in parallel with my gm pcm but then I got disgusted at the amount of work and money that was involved in it so I abandoned that and just put a 00 Camaro gauge cluster in it. Not perfect looking but it's functional. So the wires your talking about must just get jumped in one of those underhood plugs and in turn provide power to that parking lamp. If you could tell me which ones you jumped I would be in your debt because it's really bothered me that I messed something up. I was certain I hadn't I just haven't had time to investigate and the car runs great despite that one thing.

lemming104

Sounds about like what I did, although I later went back, removed the dash, and gutted out all of the wiring I could conclusively identify as "no longer needed." Thus, I don't even have any of those connectors anymore, just a tiny little one that connects those two circuits.

I'll check later and see if I can at least tell you what colors those wires are on my '03. If I have time, I'll see if there's anything in the shop manual about that part of the harness.

What's the dyno numbers on it? I see it wasn't at the shop today when I picked up some parts.
