BWM K75 starting / running problem
Hello out there, I'm new to the forum and looking for some help.
I have just dropped a BMW K75 engine into a small car (can't ride at the moment, docs orders) I have done the mechanics, done the wiring yet it refuses to kick into life.
I have got spark, I have got fuel (new injectors) and everything powers up. Crank the engine over and you get some coughs and barks, but nothing to speak off. I am getting fuel thru the injectors. I have disconnected my fuel pump and opened the throttle bodies full, turned over and got flames back up the throttle body.
I don't have a clue at the moment as I have checked literally everything. Only thing I can possibly think off is coil wiring / spark plug leads on wrong.
As far as I am aware, #1 cylinder is at the front where timing cover is.
so i have got:-
#1 cylinder to first coil - black/blue wire.
#2 cylinder to second coil - black/red wire.
#3 cylinder to third coil - black/green wire.
Anyone have any ideas and help me out?
