ok i got a 1986 325e, pulled the motor and trans together to rebuild the motor. new rings, bearings, painted, clean engine bay etc... put the motor back in "[COLOR=blue ! important][COLOR=blue ! important]Pain[/COLOR][/COLOR] in the ass" by the way with trans connected. connected everthing back up right, atleast i think and now i am not getting any spark? i switch out a working ecu, and a working coil wtf! im geting fuel i know this because fuel is spilling out of the throttle body. this car was running 1 month ago perfect! shes kinda a garage queen but wtf! any ideas on what to check?

check your reference sensors...
make sure you got fuel lines connected right...

fuel lines are right double checked that with my dd 85 325. as for the ref sensor how do i check to see if its bad?

Since you painted everything make sure your grounds are metal to metal!

well lets see... there is a ground from the oil pan to the frame checked, valve cover to the engine bay checked, and a ground from the diagnostic plug to the intake... is that all the grounds for the m20? i put a test light from the ground on the coil to the positive on the coil and tried cranking the motor and i got no pulsing of the test light on the coil. is my main relay bad if im getting fuel but not spark?

Guessing you have checked the fuse in the trunk? about 6in from your battery on the power wire?

[e30ballin]

yes checked that, it was still connected

yeah so i think i found the problem, took off the tdc sensor and it was sheared on one side, like it was making contact with the flywheel pin, i have not checked to see if the pin is still in there but i pretty sure its going to be destroyed! so looks like im going to have to get a new flywheel and a new sensor!SOB!!!!!!!!!! anyone know how this could of happened?
