You are watching: 2003 ford taurus fuel pump relay location
inspect fuel pressure. If the pump is failing, the push will be reduced than it must be. If that is the relay, it will shed pressure completely when the engine stalls.The relay is in the diagrams below
I\"ve to be having difficulties with my automobile lately vice versa, the auto sitting at idle would die intermittenly. I changed the fuel filter which appeared to aid then symptom came back and obtained worse come the point that the vehicle wouldn\"t also start unless I shoot starter liquid into throttle body in which instance the vehicle might run for 5-10 mins.I climate dropped gas tank and also replaced the entire fuel pump assy. The vehicle ran fine for 2 work after i beg your pardon the vehicle sat untouced because that 4 days. Ns came house from a trip and also tried to begin car and again the would only turn over and not start unless ns shot starter liquid into it, and then the car ran at idle because that 5 mins before dying again. Ns don\"t beleive it\"s the new fuel pump. Might it it is in a defective pump relay or possibly a bad ground?Thanks, Quadrunner(734)658-3941
turn the vital to on, and also listen for the pump, it need to run because that 2-3 seconds, if not examine fuses and relay in the power distribution center under the hood. If they room OK check the connector in ~ the tank and test because that power. Is your inspect engine light on? There will certainly be a code collection if that is the fuel pump driver module, or PCM...you will acquire P1233 or P1234 scan it, also if you need to buy a cheap scanner in ~ Autozone...It\"s an investment that deserve to be supplied on every cars marketed in the us sinc 1996...post the result, or permit me understand if the light isn\"t on, also make certain the inertia move is pessed down, it\"s in the trunk...Fuel pump driver module is behind the appropriate kickpanel, the pink/black wire is pump power, and also the whte/red is pump control, test pink black color for strength while someone turns the key to ON.
The check engine light is no on, and also I did push down ~ above the inertia button to make sure it didn\"t trip. My brothers is preventing bye morning night to hookup his obd2 computer and also read the codes for me, however when I get home from work-related tonight i will check relays and also fuses. After ~ I mounted the brand-new pump critical week I can hear the pump energize as soon as I first tried the brand-new pump, however now the sound that it provides isn\"t as loud for this reason that\"s why ns was wondering around a poor ground perhaps not supplying sufficient voltage to pump. I\"m also going bye harbor Freight tonight to choose up a pressure guage to check my revolution pressure once keying ignition
yes I\"m familiar with trial and error procedures, and also I will check the relay and fuse when I obtain home tonight.Quadrunner
I checked my fuses and also they to be okay.I pulled off rear compartment panel and also checked the inertia switch and it watched okay. I then checked the fuel pump manage module and also here space the results.Pink (PWR) v blk tracer = 12 voltsblk(gnd) checked it s okay for continuity come ground.Blk with Pink tracer (gnd) checked open up for continuity come ground.What sould other wires read? Such together the mod in and also mod out, as well as the pmp cntl?Could this pump control module it is in bad, or is over there a method to examine to check out if it\"s okay.
Fule press, 40psi spark = ok replace fule pump relay samething replace fule pump turn crucial on x2 fule press. 60 psi start & stall ~ 30-40 sec. Fule press. Dropes to 40 psi. Through engine run & stall. Scan ck 1 code p1000, no fule leak tps=ok maf=ok coolant temp=ok egr=ok. Eliminate vac. Heat from fule press. Reg. Samething. HELP!
The other thing to inspect is the crank sensor, PCM should recieve the crank signal come energize fuel injectors.

You could have a blockage in the intake street or exhaust tract. One typical thing is because that catalytic converters to rust out and collapse in ~ above themselves and also block the exhaust. Girlfriend can try banging on the converter with your hand or a rubber mallet come listne for losse metal. An additional problem can be the Idle Air regulate Valve, IACV, i beg your pardon controls idle. The is located on the intake manifold near the accelerator body. You can test that by remove it and also leaving electrical connnector on, some have coolant lines running through them leave those one, and get one assistant to aid you. Watch the solenoid plunger while your helper start the car. The should move when the vehicle starts.Also look because that carbon shop in the trottle human body by acquisition of intake tube. You might need to clean the thrttle body and IACV. When you perform so use always spray in the direction of the intake definition the direction air would flow into the entry tract. Otherwise you can force depsoits deepr into the port in the IACV.
