my car seems to be have a fuel pump over heating issue. sometimes the car will just stop runnign and when i pull over and try to start it i dont hear the pump prime. after a few minutes i will hear it prime and it starts up fine. even though my car has always run a bit stumbly at idle. the guy todl em the fuel pump is a walbro 250 cause the car was turbocharged at one point but he left the pump in. the car had a cut of switch under the seat for security reasons but i bypassed it but i do notice that that wire gets real hot. i seem to be getting enough fuel preasure. but on my car the fuel preasure gauge is on the fuel filter and i think it only reads preasure before the fuel filter. so im guessign its either the wiring for the cut off switch , fuel filter or maybe a block at the pump anyone have any ideas?
