So, after trying several things. There is a wire that goes from the negative of the coil to pin #1 on ecu. It wasn't connected. As son as we jumped it, it started.
Thanks again everyone

I have a 528i computer and injection harness that I don't need. And a 530i computer.

The more you take off that car the simpler you can make it. Do you have an electrical schematic? Believe it or not, a Haynes manual is pretty good stuff. Electrical doesn't get to injectors if the box isn't even ...

ive been getting that a lot. I thought i had a 1979 ( i was told) but the door tag says 530i. Im pretty sure its a 78 then. And no, im not getting signal to any injector.

Gentlemen.
So, we have been trying to put a puzzle together. I bought this 79 530i from a guy, and it was a mess. One of the fuel lines was connected to one of the coolant ports in the head. That kind of a mess. So, we are going to use the car for a 1 time endurance race and we removed everything ...

You got sold a water pump for a 80+ car, they used a different fan clutch which used different parts attached to them. The 79/80 changeover date isn't perfect, lots of E23s seemed to use the early style in later years, but I don't think any 79s came with the late fan clutch/water pump. so can I get ...

Thanks

I bought a water pump for my 1979 530i. The pump is identical to the old one except for the pulley flange. The old pump has a "square" bolt pattern (to bolt on the pulley) and the center hub or nose is smaller in diameter. The new pump has a "rectangular" bolt pattern and bigger center circumference ...

What's up you guys, like the title says.
What other BMW spark p cables are compatible with the m30 engine? Are m20 cables or other engines compatible? Thanks k you guys

should ALWAYS change EVERY hose and belt along with changing ALL the fluids,

This tells you just how old everything is.
Welcome,,,,Greg

This is what I ended up doing with my 75

Wooww! Big refresh! I agree, given though is for one race, I need reliability so the car doesn't die on me. Any good reference on where can I get gaskets, brake lines and front steering/suspension components ? Thanks again.

530i, notoriously bad engine. Thermal reactors, prehistoric emissions control, smog pump, even worse if you need a replacement, NLA. The 530i was peppier as a new car, the 528i runs circles around them for reliability. Getting the thermals and the pump off the engine is the best thing you will ever ...

What's up you guys, so yeah. Like the title says, my second e12. My first is a 75, which I thew in an m20 with a 5 speed and its been an amazing daily ever since.

The bug bit me again and I recently negotiated the price on a '77 and now its my new baby. 530i 4 speed.
I would like to get as much ...
