All wired up, No Crank or Fuel pump prime

It fires right up now and idles! I wired pin 8 on the EKP fuel pump relay right to pin 7 on the c101 (switched 12v). I had it tapped into another switched 12v before and that wasn't good enough I guess. -
I can get the fuel pumps to run if I run a 12v switched jumper to the fuel pump pin on the C101Leave a comment:

M3's have the dual pump system I heard I'd have to change my gas tank to run the single pump setupLeave a comment:

Why not use the deatschwerks/walbro/TRE/etc 255lph in tank pump and eliminate the in line pump?Leave a comment:

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?Leave a comment:

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.Leave a comment:

Are you using an EKP module? I don't even have one and my swap works fine without
What trans? 420g or Zf___?Leave a comment:

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.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 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.Leave a comment:

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