#66 of 165 2002 Taurus Fuel Pump? by richf65

My 2002 Ford Taurus recently started having problems starting when it has only been off for about an hour. It starts up, but gurgles like it is not getting enough fuel and then dies. I can wait a few hours and it starts fine with no issues. Is this the fuel pump going bad or something else. It seems like if it was the fuel pump, it would die while driving.

WHAT KIND OF PROBLEM ARE YOU HAVING ? If eng is hard to start when hot, it is most likely that the eng is being flooded with fuel while sittng after you shut off eng. get a fuel pressure gauge ( you should be able to get a loaner at Auto-Zone ) connect it to fuel rail, bring up eng to operateing temp, shut off eng and watch the fuel gage and see what it reads, it should retain running fuel pressure. if pressure drops down, you may have an injector leaking fuel into a cylinder when shut down. Also, there is a check valve in the fuel pump and it could be leaking pressure back into tank.
Run these tests and let me know.

I’ve encounter this problem before, it gurgles like that. And golferric’s suggestion is right. I thought I needed to replace a lot of my ford taurus parts,but a friend told me that my injector might be leaking fuel and we’ve done the same test.

My 2001 Taurus has no ground to the fuel pump relay coil.
Has power to the contactor and if jumperd fuel pump will run.
Question: does the computer control the ground to the fuel pump relay?
Is it ok to add ground? Is the fuel pump supposed to run all the time when power is on? it does when I jumper it.
 
Thanks in advance,
ST

You should Not run a seperate ground to the relay.
If I remember correctly, look in the fuse box under the hood, you should find 2 small black diodes, i think they are towards the front a box. 1 of these diodes is for the fuel pump, the other is for ??? Try switching these 2 diodes and see if this fixes your fuel pump relay ground problem, if it does, buy a new diode and WALA.
Also, check the crash cut out to the fuel pump, I think it's located in the R. inner
kick panel. Make sure the button plunger is pushed all the way down, it will be a red button.
Keep me posted

I have a 2001 Taurus (approx 130K mi) and my fuel pump is acting up. It does not consistently come on for the 2-3 seconds necessary when starting the engine. Most of the time when it's acting up, it will finally kick in if I keep turning the key off and on. This morning it never kicked in. When I got home tonight it still did not kick in and finally the battery started to run down. I hooked up my battery charger and after a few minutes I tried it again. The 2nd time I turned the key on, the pump kicked in and it started right up.
 
After a hundred or so attempts this morning and tonight with no success, the logical conclusion (well, logical for me anyway) is that the extra juice from the charger made the difference. Isn't 12 volts, 12 volts? If there were enough amps to keep turning the engine over I've got to believe there were enough amps to make the fuel pump kick in, right? I'm looking for some hints/suggestions. Even at auto zone the fuel pump assembly is $270. I'm broke and can't really afford spend that kind of money unless I'm really sure that will fix the problem. Is there a sure fire way to know the fuel pump is bad or going bad? Any assistance, thoughts, prayers, etc. is greatly appreciated.

I've been following this thread trying to figure out what to do next. The '94 Taurus we just picked up just suddenly wouldn't start; it cranks and there is spark but it won"t turnover. I'm trying to do all I can do before I have to drop the tank. How do I find this 'relay' I hear talked about, I don"t see anything in the fuse box designated for the fuel pump.

Your fuel pump relay is located in the under hood fuse box, it should show it in your owner's manual. BUT first, Get in a totally quiet location, door closed, seat belt on,
radio off, Turn the key to the RUN pos. You should hear a low hum noise for 2-3 sec.
then it stops. If you hear this, then the relay and the pump are working. Do this then let me know what you find.
