Dunno if I'll help, but I'm not a drinker...

Yes, a tired battery would slow the engine enough to prevent the pump from pulling enough fuel. This might also affect the ignition enough to cause a weak spark. Why did you disconnect the coil to change the head, may I ask?

What year is your 2002? I have wiring diagrams for most of the cars. Usually a green wire goes to one terminal of the coil and one, sometimes two black wires go to the other terminal. Sometimes the wires have been replaced with different color wires.

Hope some of this helps, feel free to ask more,

Finally finished installing a new (professionally rebuilt)E21 head on my 76A. I am not a mechanic. It was my first time and I had only this board (which is great) and the Haynes, Factory, and McCartney manuals to follow.

Anyway, the starter still turns, but no spark (running a Blue Coil and Pertronix). Also, no fuel from the mechanical pump. Again, I'm not a mechanic, but no fuel and no spark = no go.

Does anyone have a wiring diagram for the blue coil (the one that came with the Pertronix doesn't cut it).

Would a tired battery slow the turning of the engine and prevent the fuel pump from drawing fuel?

Everything worked great before I mangled it (except for bad valves and gaskets).

I've done everything alone to this point and I don't want to call in the pros yet. Any and all help is appreciated. A six-pack goes to the most helpful post. I'm desperate.

Thanks,

Tim in NJ
