2001 MERCURY SABLE FUEL PUMP HAS PROBLEM STARTING RUNS FINE WHEN STARTED
Turn the key between the "off" and "run" position without engaging the starter. Can you hear the fuel pump turning on and off every time? The car SHOULD build proper fuel pressure, then shut the pump off until its been cranked or has sat for a while. If the pump never shuts off or is pumping every time its switched on and off, I'd say you've got a pressure issue or leak in the system. Testing fuel pressure isn't too difficult either. The tools can be "borrowed" from autozone or similar store if you don't own them already. Just buy them, do the job and return them clean and complete. I've never had a problem, even with "non-returnable once used" tools! : ) These stores can usually supply you with the proper specs if you need them. You may also want toi try testing the signal to the injectors themselves. Ahgain, tools avail at autozone and the likes. Good luck!
