Fuel injectors?

[badbizy]

Replaced the head on my non vanos 95 325is with a vanos head. it started right up and ran for about a week. I turned it off, went to bed and the next day it just cranks but won't start. The fuel pump and injectors will not engage or kick in. I can jump the pump and it kicks in but still neither injectors nor the pump engages when I turn the key. WHATS UP??

camshaft sensor would be my first port of call. Do you have a spark at the plugs ? if you have then the crankshaft sensor is ok.

[badbizy]

Are you talking about the camshaft position sensor or the crankshaft position sensor?

[marti5]

Both, the crankshaft sensor controls amongst other things controls the spark, the camshaft sensor amongst other things controls the injectors, hence why asked if you have a spark !!

The relays are all firing up but I've got no spark, no fuel pump and no injector pulse
