OK, so as the weather has warmed up, my car decided, after doing away with the whole series/parallel setup system, and just one battery, to start up!

it took about an hour. I would crank it for a good amount of time, and it would turn over VERY slowly, and not make any detonation sounds (like as if the fuel injected at compression was not combusting). But the more and more I did this (remember, I have it jumped to another car the whole time too) the faster and faster the cranking started to get. So eventually the car started to bump up and down like it was getting combustion, and I could smell that familiar diesel burning smell as well.

Well, eventually, it started cranking over EXTREMELY fast!!!! And then it started and obviously, stayed running. It stays running for as long as I need it to. I never dies, nothing. IF i leave it sit for 4 hours or so though, then go back out to start it, I basically have to go through the same thing again....

ANY IDEAS??! Can someone please help me or give me a reason as to why my starter is cranking over SO slowly when I am cold starting my engine, but after so much cranking, the starter cranks the engine over like its a piece of cake????

I just don't understand. I thought there MIGHT be an air leak, where air could be entering the fuel line...but the thing is, it starts eventually, and when it does start, it runs PERFECT. no bumps, no weird things at all. It purrs like a kitten and runs like new.

ANY AND ALL help would GREATLY be appreciated, as spring and summer are soon approaching, and there is nothing more I'd like than to be cruising around town in my turbodiesel!! I'm willing to try anything!

Also, i'm thinking about getting a canister, filling it with diesel, and connecting it to the fuel line leading to the primer pump (the primary fuel line that eventually leads to the cylinders) to see if I can figure out if (if the problem is fuel related) there is a problem way after the engine in the fuel lines, or whether the problem might be I.P. related.

AGAIN, please help a very desperate man! I do not want to part with this car, and if i had to, i would get much more money for it if it actually started and ran! ( i just got an 85 500sel I'd like to get going.....)
