I am having a similar problem with a 99 ford taurus. The car will not run. The pump gives nothing. after removing the hose connected to the fuel filter to see if it would give anything or if there was a line restriction. I turned the ignition on and off a few times trying to see if it would cycle some fuel out. Nothing. After extensive electrical tests I found the pump was getting power. Thinking it must be the pump I replaced with a used pump. Still having the same problem I considered I must have got a bad pump. After reading your post I think there could be a similar problem. When turn on the key have 12 volts for about 1 to 2 seconds then drops to 6.8 volts. If you could help me with a few more details on what you did to ground the unit it would be greatly appreciated.
Thanks Vector1

We drilled a hole in the floor under the back seat and ran a direct ground from the pump to under the rear seat .

You can test by running a direct ground to the battery but we just ran a seperate one right under the backseat. Drill through floor and ground under seat ...... No corrosion to bother the ground under there.

#17 of 165 Fuel Pump and Circuit by dryflyw

Jul 22, 2008 (12:24 am)

The fuel pump in my 1992 Taurus Sedan LX (3.0L) quit working. When I took out the old pump I checked the circuit (voltage and continuity) and it checked out fine so I replaced the pump. When I put the new pump in I lost all voltage from the IRCM to the pump. It is like a relay opens somewhere and does not allow any power to go to the pump. I have remade grounds, checked the auto shutoff switch, and tested both the old and new pumps (they are working fine) but as soon as I electrically connect the pump I lose all power from the IRCM to the pump. The IRCM is fairly new (within the last year).
Any and all suggestions would be appreciated as I am getting very frustrated.

I was a ford tech back in 2000 and I'm pretty sure we had a recall on 2000 Taurus for the fuel pump, I know we replaced a slew of them, Do some research and you may be able to get a refund. (maybe)

#19 of 165 Inconsistent running problem - 2000 Taurus by rtoudal

Aug 12, 2008 (1:29 pm)

Hi, I Have A 2000 Taurus 3.0L. It Starts Easily And Runs Excellent At An Idle For As Long As You Want. The Problems Start When It's At Operating Temperature And While Driving. It Will Sometimes Miss Erratically (very Minor). Then Sometimes It Will Miss Severely Or Quit Altogether. Or It May Almost Quit And Catch Again And Run Fine. Sometimes It Is Worse Driving Uphill - But Not Always. Heres What I've Done So Far: Replaced The Spark Plugs And Wires, Checked The Catalytic Converters, The Injectors Have Been Cleaned And Tested At 100%, The Idle Control Has Been Cleaned And Checked, The Fuel Pump Seems To Be Working Fine. What I Need To Know Is Where Do I Find The Ground Wire For The Fuel Pump And Does The Fuel Tank Have To Be Dropped To Get At It?. I Also Need To Know The Fuel Pressure When The Engine Is Started Cold And When At Operating Temperature. If Anyone Has Any Other Ideas As To What The Problem Is Any Help Would Be Appreciated. Thanks, Bob

Might be wear in the gear pump gears not reaching 30 psi minimum. If pressure does not pass 30 psi, fuel at idle or while engine off and hot condition, might vapor lock. Fuel must relieve at Fuel Rail regulator, passing back to tank to cool off.

#21 of 165 Fuel Pump Elec. Problem by csoria

Hi, Iam having a electrical problem with my fuel pump, the car is a Ford Taurus 1995 3.0. a family mechanic replaced the constant control relay module after checking the inertia switch in trunk area. This did not correct problem, he said there might be a problem with the fuel pump and he would check on price and availability and get back with me. Iam a a/c mechanic and decided to do some troubleshooting my self. I did a continuity test from the (ccrm) pink wire black strip at disconnected wiring harness thru inertia switch to fuel pump and test was ok. I ran a hot wire from the + post to the outlet side of the inertia switch leading to fuel pump and the fuel pump energized indicating that the fuel pump itself was working. When the ignition switch is on or in crank position voltage is indicated past the inertia whitch but the fuel pump will not energize. Note the ignition switch itself is very wornout.

I, found a electrical test to check power to PCM from CCRM only and the electrical check out, tested good. The CCRM test pins at harnes and CCRM module tested good.
