The main and fuel pump relays have absolutely nothing to do with it not cranking. Now here are some things to try: Measure battery voltage with key...
Does it crank but not start or no crank? I'm not talking about the ECU (engine computer), I'm talking about the display just to the right of the...
It is a good idea to replace it soon just because of the age. At any rate, if it does not crank, it is not the relays. If it cranks and does not...
Getting geared up for this now. We'll be in the Spaten tent. At least at this show I'll get to see the Spaten girls! We were so slammed at Vintage I...
The battery may just be too weak to crank the car after sitting all winter. Try jump starting it and see what happens. If that doesn't work, report...
I vote vacuum leak. It is very common on those cars. Have you done all the intake gaskets? Throttle body gasket? Valve cover gaskets? If not, 150k...
Wow, that was a crazy time! I never made it out from behind the table at the MHE tent. So who was there?
It would not be too difficult to swap in an M42 with its injection, though the M44 EFI is a little more advanced. It would even be possible to add...
That article was probably written a long time ago. There are no options for chipping the ECU, the injection system is finicky, and the system is just...
What year and model car do you have?

Could also be a faulty capacitor in the cotrol unit. Can be repaired for about $1.00 if you can solder.
Is the check engine light on? It may not be electrical. It could just have a vacuum leak that lets it die at idle.
The most I can afford is a couple of 84/85 318i strippers.
If the code is because the cam timing is too far advanced or retarded it could be that the cams were not set properly when the head was replaced....
We'll also have tons of swag and parts for sale. T shirts, very nice pocket screwdrivers, E28/34 upper shock mounts, Spax springs and adjustable...
What chapter are you in? We tried to find info on that and weren't able to turn up anything, so we are having our own BBQ. Know anyone that needs a...
The ABS moduel can be rebuilt by modulemasters and will not need to be recoded. The throttle has been problematic on these and on the 6 cylinders and...
The plug on the valves has 3 wires. One should be power with key on (IIRC) and the other two are the ground signal from the IHKA to close. If you are...
I would assume that your heater valve has failed or that the heater valve is not being told to close (it defaults open with no power or ground to it.)
