Engine, out, in, and still not starting

[325_driver 422]

hey guys

e30

m20b23

its got fuel,

spark

compression

not firing at all, have tryed dizzy in every possible location, clearances are fine, etc

any chance this thing in the photo has any thing to do with it? where does it plug into ? its not the one that goes to the AFM, looks like its the one that goes to the valve thats usually infront of the afm, which isnt there. Might be some model variance.

How many pins in that plug? Is it the TPS plug?

Engine requires:

Compression

Timing - valve & ign

Air

Fuel

Spark

If it has all those - it should be going.

Dizzy timing is specific - no point in trying random settings

Get the engine on TDC (or just before) on compression & set dizzy for firing on no1

Thanks for that,

um it has 2 pins, well 2 wires, brown, and brown/white stripe, what does this connect to, possibility it has been removed, the old owner has done some interesting DIY / modifications, but worked fine before taking it out.

Am removing cam covers as we speak, to do timing propperly, any one got a e30 m20, 323 / 325 fsm, or could they direct me to a diagram, with what lines are facing what

Thanks heaps

It is firing now,

if im to take a guess,

since the clearances seemed WAY out, my brother looked at the 0.025" measurement instead of the 0.25mm measurement, easy mistake if your not entirely with it !

and dizzy cap was facing various crazy locations, they are very precise things those m20's

so take note, tripple check clearances, tripple check tdc marks before putting together, can be a time wasting experience.
