1987 325E fuel issue.... HELP!

I have an issue with fuel delivery. The car will start, it will get pressure at the rail (37 psi), itll run for a while... when the car gets warm, the pressure fluters and drops to zero and the
engine dies. It is then difficult to start, sometimes, just to do it all again. there is a new filter on the line. Jumping the fuel pump relay works fine and pressurizes the rail. Can a fuel pump come on and off if it is dying or does it just die?? What could this be??

It was the external fuel pump. I stuck a screwdriver on it and waited till the car warmed up a bit and listened to it stop. changed it out and voila..

How did you replace a fuel pump in 11 minutes (time between first post and second)?

Probably took 3 weeks to find the problem but wanted to look smart but forgot to change the date and time of first post.

That is the time the message was received by the server; my news server has he posts one minute apart. He could have sent them 24 hours apart but if they were delayed along the way then they would arrive much closer together.

Bad fuel pump relay would be my first guess. Main relay could be bad too. And don't forget corrosion in the fuse box either, which is a popular one. --scott

Had a similar problem with my old E38 --------- dodgy fuel pump - swapped it out and never a bother since - car now sold and still going well.
