2001 Focus parked about 9 months fuses & relays are good change fuel filter battery is good will crank drains battery started with starting fluid can hear the fuel pump kick in cleaned the dsfm


You have not mentioned whether you do a OBD fault code test on this, if not do that and post the results. Also jumper the fuel pump relay socket under the hood so it stays on all the time, you could have a defective starter switch, in this scenario the fuel pump is powered up as long as the engine is cranking, but as soon as the key is released to run position it shuts off.

My 1999 the engine keeps just shut off while driving down the road the engine keeps turning but wont crank I put some engine starter in the carb.and it tried to start.could it be the fuel pump


if it was the fuel pump engine should start with starter spray at least for a second or two, so, it sounds like your fuel pump is bad.
turn ignition to run and try hearing the pump run.

Just quit running when you turn key over should you able to hear if fuel pump is kicking on


The fuel pump will run for about 1 second only and then the system computer shuts it off unless the engine starts or is being cranked over with the starter motor, so repeatedly turn the key off and on to keep it running or at least supplied with power. You will hear a low hum near the filler neck if the pump is working. I have this same truck and have replaced the fuel pump twice. One hint never run the fuel level lower than 1/8 tank or the fuel pump will overheat and that shortens the life of the pump dramatically.

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!

Replaced starter and wont start. Im wondering if it is the shut off switch in the trunk? does the switch have to be up or down?


the starter cranks the engine, the switch in the trunk has a button that you depress to reset the fuel pump. if the fuel pump doesnt operate then the switch may tripped, the button is DOWN. So does the engine crank? does it not crank? cranks but wont run? if it cranks but wont run, then check the switch in the trunk. Power goes to that switch and then to the pump, so if that switch has power going through it, and the pump doesnt work, the pump is bad. when turning the key on you should hear the pump go on for 2 seconds.

Car cranks then an hour later won't crank


Battery or starter. Sometimes the battery will have enough power to activate fuel pump and dash lights but not enough to turn starter.

Have to use starter fluid to start my car


Starving for fuel. Start by making sure the fuel pump is running. Turn the ignition on without starting the car and listen for the pump. It should run for a few seconds and then shut off if you don't start the engine. If you hear nothing, check the fuse. If the fuse is good then it can be a defective fuel pump relay, pump itself. If you hear the pump run and then shut off, suspect a clogged fuel filter, defective fuel pressure regulator, or an extremely weak fuel pump that is running but pumping no fuel.
