I have wasted 3 of my spare fuel pump relays in 2 days. Each of them run about 25 minutes then "burned out". they are very hot when touched after the car stalled.
500sel ran fine before each relay went dead. There is no noise from the fuel pump. Fuel pump and fuel filter are about 30k mile old.
I made a jumper, installed it to bypass the relay, car starts an runs fine again. I am frustrated, of course.
My question is:
(1) Can I just drive with the jumper I made? The fuel pump does not run unless the ignition is on. Is it safe to drive like that longer term?
(2) Can the pump simply bad (draw too much current, shorted) in spite of no noise from it?
(3) Maybe the filter is due for replacement? But the car runs fine?
It is too messy to fool around the fuel system to me. Did that 30k miles ago, honestly not really interested in doing it again.
