Problem is in common-rail druck sensor, engine has a 2x sensoren - front and rear. In any event, whatever it is, without a diagnosis can not do.

What could be the problem, I have a bmw 730d the pump runs but no fuel coming out through the injectors?

Plugged Fuel filter; Bad injector relay ( not turning the injectors on );Fuel pump not putting out proper pressure; Kinked line. ANY of these will cause the problem you have.

Hope this helps

My 1994 BMW 740i only cranks and never runs.

Have you run the fault codes first as it may not be the fuel pump. Find out what is faulty before you spend good money on what is not faulty.

My bmw 730d 2004 is blowing out alot of black smoke what does this mean?

Black smoke from the exhaust is an indication of the engine running too rich. Probably bad fuel injection system.

730d/ key is not accepted into the holder...i have only one.what can i do?thank you

Check with your local BMW dealer. If there is supposed to be more than one key for your vehicle, they can not only tell you, but they can also cut a new key by looking up your key codes using the VIN on your car. If there is supposed to be only one key for your vehicle, they can assist you in getting any malfunctioning key cylinders repaired or replaced.

My guess is the screeching sound is the belt slipping. Check the tension and if slack this can be taken up by adjusting the alternator a little bit further out from the engine. The sudden cutting out sounds like a fuel cut-off problem. Check the fuses and the relay to the fuel pump. If all OK, check that the pump is operational and that the in-line fuel filter is not clogged. If fuel still fails to flow you may need to look at having to remove the fuel tank to check that the fuel pick-up pipe in it is clear.

i do feel you are being given a bit of the stuff that comes from bulls here,the odd bit of plastic entering the cylinders would only melt then burn away ,i had trucks **** the air filter in before now and only had to remove the inlet manifold to get teh last few bits out .No i would take it to another garage and get them to have a look ,i think it could be the erg valve and /or something in the inlet manifold blocking the air flow .
