Hello-

I have a 1989 740GL that died at a stop light a couple days ago. I pulled up to the light stopped, and the car died. It was still turning over, and the battery was delivering full power and so I realized it was not getting fuel. The car has 180K and we have had it since about 90k I assumed it was the fuel pump since it had never been replaced. So, without testing it I replaced it. The car still didn't start and was not getting fuel. So, first I noticed it wasn't pressuring up when I turned the car on. So, I tested the power leads with a meter and there was nothing. So, I replaced the fuel pump relay even though it was replaced in 2000. I still do not have power at the fuel pump.

Any ideas on what else could be wrong and where to check?

Thanks in advance!!

Hi Matt.if your car is equipped with an RPM sensor located on the bell housing on top of transmission,this sensor can fail anytime especially with high mileage cars.when this sensor fails it will not provide any signals to run the fuel pumps.check the wiring to the sensor also.this is covered in the FAQ.hope that helps and post back on your findings so we can help.good luck.charles.

I will be checking this later today. Would a failed RPM sesor cause an error code/check engine light? Just wondering. Thanks!

NO,at least not in my case.i had a 90 740 and when the RPM sensor failed there was no codes stored.good luck again and keep us posted.charles.

maybe when your pump died, it shorted and blew a fuse?

Good idea. Just to be sure I replace the fuel pump fuse. Still nothing thanks for the suggestion. Simple things first is always good.
