Fuel pump relay question
ive had a couple posts about my turbocharged NA engine and how the car would shut down after a bit, but i think i may have finally came across the problem and i wanted to know if anyone else has encountered the same thing.
which would be the fuel pump relay, it is an S5 and one person i have talked to told me that the fuel pump relay may be bad, because sometimes it will heat up and turn the fuel pump off, and then not turn back on untill its fully cooled down.
if this is my problem, is there a way to bypass this relay, or do i simply replace it?

What fuel pump are you running?
It is possible you are overheating the pump and it is shutting down. Typically, if the resistor relay is going bad it will blow the 15A engine fuse. There is also the possibility that it is the circuit opening relay or the ECU. Try jumping the check connector, this will bypass the fuel pump relay, if the car doesn't die then you have found the problem.
