Promblem starting my 330ci HELP!

radames15 · 10-20-2011, 04:22 PM

Hi people I'm having a problem with my 2004 330ci aut(not zhp). When I try to turn on my car it starts but didn't turn on,other times it turn on and off very fast but after do the same thing like 5 times it starts normally and sometimes also the light from the transmission(at the left of the letter of P,R,N,D) went on. If I keep playing turn on and off the light comes off and I can drive the car normally. The codes are camshaft sensor,crankshaft sensor,air mass meter...crankshaft sensor and air mass meter are new. I think it's maybe the ECU...What do you think? I read somewhere I don't remember that the anti theft system send wrong codes and didn't start the car, that I have to change the ECU...

replace the sensors? why would it be the ECU?

Possibly the fuel pump, but need to know more. It could be triggering the other codes since its "hiccuping" to get started right now.

the crankshaft sensor was replace...yes maybe it's the fuel pump thats my next step...i think its maybe the ecu because I have a vw with similar sympthons and was the ecu but I dont know my car has only 70k

Today I check the car and its a electrical problem..there is no current in sparks when the sympthon occurs...what do you think? Ecu?
