All wired up, No Crank or Fuel pump prime

[synergy141]

I've pretty much finished my swap and now it's time to fire. I've got Andrews Harness installed but I'm getting no cranking or priming from the fuel pump. The power is there but I must be missing something. Wiring is my least knowledgeable part of this whole swap. I've gone over all the threads and wiring diagrams and I cannot figure it out. If someone could point me in a direction to start at that would be great. Thx

Troubleshooted all night, I checked all the grounds and 12V Ecu power wires. Still no crank or fuel.

ICV is buzzing, and green relay in the harness is clicking.

XC0001:

Pin 7 - 12v reading
Pin 8 - 12v reading

Pins 4-6 All Grounded

X6004:

Pin 6 - 12v reading
Pin 26 - 12v reading

X6002:

Pin 23 - 12v reading


Grounds:

-Engine Arm to drivers side chassis rail

-Hood ground

-Passenger Coolant Reservoir tray ground to the head (This is where a few of the wiring harness grounds are attached to.

When you turn key to on, do you hear the fuel pump prime? I removed the rear seat to hear it better.

If it isn't even cranking, take a look and make sure you're getting power to starter and all connections on starter are correct

No I don't hear my in line walbro prime under the car at all, I can try and remove my rear seat tomorrow and see if I can hear the other fuel pump.

My starter connection looks like this but the "30 H wire terminal" is hooked up to the far left 13mm nut terminal. I can jump the starter with a screw driver so it does have power. It doesn't seem to be grabbing the flywheel though. It's just whirring. I may have to remove it and get it rebuilt. It may have been screwed up from the wreck the donor car was in. But for now I need to figure out the power issues.

I just ran a jumper wire from pin 18 on the C101 right to the field terminal on the starter and I'm getting crank now!

Cool. Turns out theres no 30h on an S54 starter - it is only 3 prong vs the 4 prong starter. There are a couple ways to do things but it looks like you figured it out.

Next is to make sure your fuel pump is working and that you have the E46 M3 fuel pump relay and at least a 15A fuse installed in the E30 fuse box fuel pump fuse spot.
Did you ever figure out where that yellow "random wire" with the eyelet goes from your other thread?

I'll do that. I have the black E46 Fuel relay installed but I have not put a bigger fuse in the fuse box.

I still haven't found what that random yellow wire comes off yet? I think it might come off the the fuel pump relay connector.

I'm just having trouble with the starter not engaging the flywheel, I don't think I'm getting enough voltage through so I'm going to check all my grounds again. I even tried another starter with the same result.

The car will idle/move around a little with the 7.5A fuse so is ok for testing, but it will constantly blow unless you put a 15A in slot #11.

The yellow wire definitely comes off where the E46 M3 fuel pump relay plugs in on Andrew's harness. Check out the 5th/6th picture here: http://www.r3vlimited.com/board/showthread.php?t=275468
You're not going to get fuel until you get that back where it belongs

What starter and flywheel/transmission are you using

I'm going to be testing the EKP wiring today. That connector ties in with the x60002 on the dme and the 4 wire x6021. The yellow wire is for pin 6 on the relay connector which is a constant 12v.

I'm using a stock S54 starter and UUC ltw flywheel. Buttttt my starter is engaging and cranking now. I ran a jumper wire between pins 15 and 18 on the c101 and it cranks.

Slowly getting there.

[diesekte]

Are you using an EKP module? I don't even have one and my swap works fine without

What trans? 420g or Zf___?

[synergy141]

It's a 5spd ZF.

I found the issue now. A mouse or a rat chewed Half the wires in Andrews adaptor harness. Stand by, this will fire today.

[synergy141]

It runs! Almost... I'm having fuel pump issues. It's not staying powered up

[diesekte]

Are you blowing fuse 11?

[synergy141]

Nope, not blowing the fuse

[diesekte]

What pump(s) are you using?
Early or late model?

Are you using E46 M3 fpr? How/where is it mounted ? Sure it's good?
