Fuel injectors?

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.

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

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
