6 cylinder swap issue.

Post by korangatang »

Hey guys! Well I finally got the new motor and trans into my e21. The they both came from an 87, the trans a 325e and the engine a 325i. It went smooth, I made the mounts and it bolted right in. I ran my fuel lines and did some of the wiring. Tried to start it, it cranked and cranked. No start. I have no fuel or spark
I'm very tired and beat from working all day so I'm going to try and explain this the best I can. I have a feeling my wiring is a little off. Does anybody have some sort of list of every wire I need to wire in?? I tried looking at a few things but idk. I'm probably rambling on at this point

This looks like what you need. Allso have you connected the main earth strap to the chassis?

You sir are a life saver. I followed the wiring to the T and got fuel. I then learned I didn't have the power hooked up to the constant located on the passenger side and was grounding it instead. So once that was fixed the bad boy started right up. Now it's all downhill!

I'm at school 3 days a week. I can take some photos friday! I banged up the paint In the engine bay dropping the motor in because I was doing it myself (I know.. not safe). So please excuse that in the upcoming photos!

But what I have left is hooking up the master cylinder, slave cylinder, rad set up, weld the driveshaft, exhaust and a little intake work in order to get the car to touch the pavement . That'll start Friday. I'm thinking radiator, driveshaft then exhaust
