Ford Mustang Fuel Problems
When the temperature is below 50 degrees and the engine is COLD, on KOEO the fuel pump runs continuously. This prevents the engine from starting. If you leave the key on for a long period of time (greater than 10 minutes) the pump will stop and the car will start. However, the engine runs very rich (with low power) until it heats to normal operating temp. Replaced Fuel Relay, ECT, and wide open throttle relays. ECM reports secondary Fuel Pump Circuit Failure (code 95). At a lost on correcting this problem. What can I test or check next?

YES, I'M YELLING!
Need help?
Is the a security system lock out?
Any suggestions? -Ed
Most mfrs do recommend Techron though, including Ford. I don't have the link but did see the actual article/site where it shows all mfrs who recommend the stuff because it was passed around on a dedicated Mustang forum. Mercedes and Porsche were included among others and apparently Techron works miracles without any side effects or engine damage. It is the only product that can claim that IIRC.
every time I try to fill the tank up with gas the automatic shut off shuts the pump off,
I cant even get a full tank of gas anymore even if the tank is at empty or especially at1/2 a tank, I have called Ford cs and taken it to my dealership also .
I actually took it to 8 gas stations today I got amounts like 22 cts 38 cts 98 cts $4.00 $198 and 37 Cts 17 Cts etc , I try shells, exxon, mobile, valero,Tetco & conoco.
The dealership tells me there is no fix for the problem it is a design issue with that particular tank and showed me A TSB bulletin on it describeing this issue as a Slow fuel filling issue, and no fix for the problem..Its more like a no fuel fill issue...
Ford says it is operating as design, Does that mean every 2005-2007 mustang has similar problems,
I have actually allmost run out of gas and only could get 22Cts worth of gas in my car If anyone know anything about this please post comment ..Sick of my mustang
Thanks soooooo Much
It is not clear that replacing the tank on an 06 or 07 that had the redesigned tank originally will fix the problem.
Second, different pumps do produce different results. I have a 2007 V6 with 30k on it, purchased in 10/07. When I first purchased the car I noticed that I had the fuel fill problem at various different pumps in NJ. I was always able to do a complete fill up by moving the nozzle around etc.
Continued, After the first few months, the fuel fill problem disappeared and has not re occurred. :confuse:
People have stated here and on other forums that it seems some pumps are just 2 fast.
Third, Here is a link to a "pirate" fix. This repair is not approved by Ford and not covered by warranty. http://ratstangrestoration.com/05_mustang_tank.htm
I wish you the best of luck trying to resolve this problem and hopefully Ford will figure out what the problem is.

Its very important that you do not put generic gas in your car. Visit www.toptiergas.com to see what i mean.
FORD: 2005-2006 Mustang
ISSUE:
Some 2005-2006 Mustang vehicles may have the MIL on with DTC P0463, or erratic fuel gauge concern. This could be from sulfur contamination present in the fuel. Sulfur will cause an open or high resistance on the fuel sender card leading to an erratic fuel gauge reading or setting a P0463.
ACTION:
Follow the Service Procedure for verification and repair.
SERVICE PROCEDURE
Perform normal Workshop Manual, Section 413-01 procedures to verify the concern. If the concern is verified proceed to Step 2, if unable to verify the concern do not continue with the TSB.
Replace both the Fuel Level Sensor and the Sender Assembly (Sender card on the Fuel Pump Module) per the Work Shop Manual section 310-01.
NOTE: BE SURE TO CHECK FOR DTCs IN ALL OTHER MODULES.
Good Luck.
Multiple re-fills since then in my home turf.
Filling the gas tank was absolutely not a problem except for 3 stations in a row then one more later - all in southern Salifornia. With the very difficult to seal vapor trap on those pumps, I could fill more than a couple gallons before I gave up from all the pump stops.
Perhaps its not merely the car, is it poorly designed or maintained pump nozzles?
