Customer Question
It is cranking but...

It is cranking but no gas and sparks. What do you

Mechanic's Assistant: Has the vehicle turned into a gas hog? And how does it start -- same as usual?

It doesn't start at all.

Mechanic's Assistant: What is the model/year of your BMW?

2000 BMW 740il

Mechanic's Assistant: Are you fixing your 740il yourself? What have you tried so far?

I fixed many cars already, but this is my first experience with BMW. I checked all the relers and fuses. I by pass the fuels pump and it good. I pull a spark plug out to check the sparks, no fuel. Please help me.

Mechanic's Assistant: Anything else you want the mechanic to know before I connect you?

I tried to reset the computer, still no gas from the pump and no sparks

Hey how are you

have you checked or replaced ckp sensor ,crankshaft position sensor ,if this one is not sending signal to dme that car in time ,the dme will not fire the coils or pulse the injectors ?

do this for me lets double check no spark and fuel,if you get a starting fluid can and spray inside the TB body does it start and die,if it does ,means injector not pulsing and the coils are ,if it does not start ,replace sensor ,that is most common ,now off course be best to have tools and test for power and ckp signal etc

did you scan it and retrieved any fault codes
