This is my take on the problem:
I've got somewhat of a power drain I think, and my battery isn't coping too well with multiple starts. After about 6-7 it just clicks the solanoid and doesn't turn over.
The car has been unable to start for about 5 months.
I drained the fuel tank, and it was full of water and crap, then filled it with 98 octane premium unleaded, with a 1:20 ratio mixture of pure methylated spirits.
I then yesterday, pulled the fuel pump relay (large black relay in the forward relay box) and connected jumper leads from my 525i E34 to it. Cranked it for about 5 minutes off and on.
No firing, then I was getting firing on a couple of cylinders, with no fuel comming to it since the relay was removed, and after 5 minutes it stopped firing, as all the fuel that was in it was burned.
I put the fuel pump relay back in, turned the key, and instant start, on all 4 cylinders, smooth up to redline and perfect idle.
Started it a few more times and then left it overnight. This morning, starting it, it was firing on 2 or 3, then I stopped it and went to crank it again, and it didn't have the power to turn over.
So, I am assuming that it is flooding, possibly because of the cold start injector, which I have cleaned with CLR.
One question, my cold start injector is giving a continuous stream of fuel, no pulses, just a spray. Also, at what point does this injector stop working? Because while testing it, it didn't stop.
Will it start ok without the cold start injector connected?
Does this sound consistent with the cold start injector flooding, as I'm pretty sure flooding is my starting problem?
