I got to work this morning and when i parked i heard this high pitch noise from under the car, upon investigation it is the main fuel pump. Now i have never heard this before but it came and went, i drove home and the noise is gone. Now here are a couple of things, I heard it when i got to work off the highway, i drove back roads home and noise went away but there is a 50 mph zone on the way home and after that speed zone i heard the noise again, but when i made it home it was gone. So it seems to me like high speed driving is making this noise and at low speed it goes away, is the fuel pump heating up at high speeds and cooling down at low speeds or am i just crazy? My other question is, is it going to poop out on me any day or what? thanks
