e39 stall issue re-surfaces...

[brewsterE30M3]

Well I thought I was out tof the woods....however, the old gal stalled out after only 20 mins. of highway driving.
Previously we had replaced the Fuel Pump, fuel filter, and Crank Position Sensor. It ran fine for about a month, even after 2 hrs of highway driving.
So then it stalled after only 20 mins. and I was dumbfounded.
I had it flat-bedded home, and again tried strating, it would turn over but that's it. Then checked the fuel pressure at the rail schrader valve.....ZERO.
Then checked the fuse box (the one in the trunk) and found the F/P fuse (15A) blown. Replaced it and it started right up!

OK, so why is my F/P fuse blown....faulty F/pump? F/pump overheating?
or ground problem?

The F/pump (Bosch) is only 6 months old.

Anyone have a similar issue with their e39?

TIA,

I would replace any associated relays. I'm not saying this is the fix, but since you replaced the pump and filter, at the same time I would have replaced the relays. Just sayin....

Check the current draw to the fuel pump. If excessive (>fuse) wire direct to power and check current draw again. Could be faulty supply power circuit - ie wiring, relay etc. But first rule out pump.
