View Full Version : Fuel system possibly shutting off, can it be the relay?

I need to know for sure which relay goes in the slot for the fuel pump (under the hood). I currently have a Siemens 5170 that has been there since I owned car, but recently my car has been stalling when it gets pretty warmed up(stop lights, city traffic, bout 210 though). I hope its not the fuel pump, I don't know anything else that would cause this.

*reason I'm looking at fuel system is once it dies, I can prime the fuel pump a few times and it starts back up.

just my opinion but i think you answered your own question ..id be leaning towards a new fuel pump

Or possibly a fuel filter.

Try the filter first just to see what happens. You're going to want to replace that if you're putting a pump in anyways. Its a cheaper fix so that may limp you along for awhile.

always try the cheaper way first

aka: start with the fuel filter

Or fuel pressure regulator.

Or fuel pressure regulator.

Not likely. The engine would start running lean (like crap) before it'd stall.
