Fuel Pump Issue - '92 SHO
I just bought a 1992 SHO I'm going to refurbish. Here's my first issue: When the key is turned on, the fuel pump continues to run regardless (I'm going by the sound).
Of course, I've seen to it that it has gas in the tank; the engines starts and runs, idles just fine, and there is no gas leaking anywhere. I know the fuel could be just returning to the tank via the bypass, so what sensor or device tells the pump to stop when the fuel pressure is adequate, or is the pump maybe being fooled into thinking the pressure is down?
