Nice. Let us know how that wiring harness will workout. I'm interested in going the same route.

Will do! It's been great so far. Came labeled and everything for me

Did you check out the DIY I wrote?

[cmeptb13]

Sure did. Can't wait to get my swap going.

Awesome.
Good luck with it, it has been fun working on it

[craiggroves91]

Well, I'm funny
I also just realized I haven't had the coil pack harness plugged in

[craiggroves91]

Tomorrow I try to start her :)

Will update you all

So SHE FIRED UP TODAY! (video coming soon)

A couple of issues though:
1. My s52 MAF that I had extra from my old m3 doesn't work on my s52 plug, yet my friends s50 OBD1 MAF's plug matches? Any reason this might be?
Maybe the PO converted the plug for a euro 3.5 MAF?

2. After we started it and gave it a little throttle and died when it was returning back to idle and since hasn't been able to start. Is this cause there was no MAF plugged in and it wasn't able to compensate? We also didn't have a filter on

Yes lol.

[craiggroves91]

Yes lol.

Yes to all of it?

My m3 could run just fine without a MAF

(I'm the one starting it in the yellow shirt, which says hot and juicy)

Congrats. I can say I recently know this feeling!

[craiggroves91]

Damn, can't get it to start again.

Is there a chance the FPR is bad? When I undid the fuel rail there was lots of fuel backed up in there and it leaked everywhere.

Is it a problem with me running the M50 fuel rail?

No I am running the M50 fuel rail myself.

You are certain the fuel lines are running the right way? They could be backwards, and the FPR could be bad, but that is an unlikely coincidence.

I would personally start tackling things one at a time. Check for major intake leaks, then for spark really quickly, then check fuel.

You give us a better idea of what happens when you try to start it? Does it simply crank and crank? Does it catch occassionally like it might start but then doesnt? Nothing at all?
