Does anybody know

What should I do to start up my car? I have a 1999 323i with 159k miles on it. The car is supper clean and was ruining perfect until last week. I drove the car, parked it and next day tried to start it up but the engine didn't run. It cranks but doesn't run. I had my regular mechanic checked it out. Apparently there is no electricity on ignition coils. He checked everything with scanner, no computer code , changed the crank sensor, everything look normal. Just when you start it looks like is going to turn on, but it won't happen. The fuel pump woks just fine. Does anybody know what is wrong with it.
I am trying to avoid taking it to the dealer since you know how they usually treat you money-wise and for this car I really don't have that much money to spend on it.
Thank you so much for your help, friends!

Was going to say fuel pump but reading closely I see you've checked that. You guys checked fuel pressure at the rail on the engine? Could be a clogged fuel filter.

thanks for your reply.I am sure Is not fuel related ,since gas in running when we try to start the car. there is no electricity behind the coils, therefore, no sparks on the spark plugs.

I think this means your ignition switch. Do you have a second key you can try?

I doubt it's your chip because it would not crank at all if that were the case. I just went through that ordeal this week. The EWS locks out the starter if it does not recognize the chip.

You gotta explain 'gas is running' to me!
I always like to broaden my skills.

Big Al, here is the fault diagnosis sequence. You may want to start at step 15 to bypass what you say already works. Good luck. BTW I have a feeling, but can not be certain that your neutral safety switch may be the culprit.

I guess that blows that theory. LOL I somehow had forgotten that the car cranks. Guess that makes sense because if the car was a manual trans and the clutch wasn't pressed in the car would lurch. I do realize that auto and manual use 2 different types of switches. Thanks for the reality check!

I also discovered than a manual has three switches that may (or may not) affect starting and vehicle operation; two on the cluch pedal mechanism and one on the clutch master. The two on the pedal appear to be the same.

Leave it to the Germans (I am one!) for overkill.
