1994 318i ignition problem.

[rickeyv1134]

alright, i posted a few questions in another thread. i have yet to get my car running, and have a couple questions that i cannot find a straight forward answer to for this year/model car, and a general question as well.

1) what order do the plug wires run, the way they are on the car goes: on the coil packs, from front to back-headlights to firewall 4 1 2 3. and on engine front to back- 1 2 3 4

i have read all different orders. for the coils and engine. are there different orders it could be?

2)which relay is the ignition relay, and where is it located? everything i find says a different relay, some diagrams dont even match what is on my car...

3) the crank sensor senses the gear-thing, i get that, but theres a large gap in one spot on that gear, i'd say roughly 1/4-1/2 inch gap, like two teeth are missing? is that normal, or did it somehow break?

4) how many cold cranking amps does this car need to start? i have a used battery in it as of right now, its putting out roughly 500 CCA's...
any info back would be greatly appreciated.
