Customer Question
The fuel injectors are...

The fuel injectors are not pulsing

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

That's the issue... it does not start

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

It's a 2000 e38 740il m62b4.4tu

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

Yes I am. I've replaced fuel pump and relays plus fuses that go with pump. New fuel filter, new battery, new valve cover gaskets, new spark plugs

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

What is happening I believe is the dme is not sending a plus to the injectors making the car not starr because water has gotten onto 2 of the 5 plugs of the dme making the pins oxidize.

I do not have a bmw branded scan tool no. I do not have a 20 pin connector either for the obd plug in the engine bay. Only scanned via the obd2 port in the cabin
BMW Mechanic: Greg, Technician replied 4 months ago

should still work if your scan tool has live data .

That is my point the dme is not getting any single from the injectors because the connection is bad
BMW Mechanic: Greg, Technician replied 4 months ago

Im going to open this back up and see if another of our BMW tech is on line .

The car thinks there is nothing wrong because the car thinks there's a perfect connection when really it's a bad connection so the computer tells me everything is ok
