Can you list what you have done to the car? I see 5.4 Cobra so Im assuming 4v 5.4. What heads? What intake? Fuel? Are you running anything stand alone? Have you checked for a crushed power to your fuel driver? Any recent damage?

Please list more information about your car and the parts/ modifications done.

Kinda sounds like a short and something has gone bad in the wiring somewhere.

4vGT · January 31st, 2012, 12:15 PM

Happened to me, Im from CO and got stranded in CT...

Problem? FUEL PUMP

Happened just like this- then the PATS went to hell.

So is it still run by the factory fuel driver and ECM? Hmmmm..... What pump(s?) are you running for fuel?

Sounds like a hell of a setup!

Any PATS problems? You are getting fuel pressure to the rails? Do you have a FP Gauge?

Tang Stang · February 1st, 2012, 09:30 AM

I'd start by tracing the circuit the multiple blown fuses were on. There's obviously a short there.

4vGT · February 1st, 2012, 10:08 AM

If he is running a higher draw fuel pump or the like though, he could trace the wires all day long *PITA* and wouldn't find the problem. Im thinking something is drawing way too much on the stock setup.

Tang Stang · February 1st, 2012, 11:26 AM

He may be, but from what I gathered from the info he gave us is that the car ran fine for quite some time before suddenly blowing multiple fuses on the same circuit.

4vGT · February 1st, 2012, 11:29 AM

Very true. However I really think its the fuel pump driver in the fender or the pump or pump wiring. The same thing happened to my car. Exact same. Drove to work fine, shut it off, and went to restart and nothing-

Replaced the blown fuse, and upon further investigation the harness that the pump was on actually shorted from the controller (loose connection caused resistance)

5.4cobra · February 1st, 2012, 07:12 PM

Sorry fuel pump out of a 03 focus

5.4cobra · February 1st, 2012, 07:13 PM

Fp gauge reads nothing till i by passed it at the tank

4vGT · February 1st, 2012, 07:14 PM

Ah! Have an OM meter? Start at the pigtail that plugs onto the tank, what does it say?

Money says your fuel driver is out

5.4cobra · February 1st, 2012, 07:47 PM

What is a fuel driver

4vGT · February 1st, 2012, 07:53 PM

CCRM

5.4cobra · February 1st, 2012, 08:13 PM

I bought a new one didnt change any thang

5.4cobra · February 1st, 2012, 08:13 PM

Those are pricey

4vGT · February 1st, 2012, 08:19 PM

Yes they are. Your problem lies between your fuel pump and your CCRM- Anything aftermarket?

5.4cobra · February 1st, 2012, 08:21 PM

No all fuel is factory excluding pump and injectors and regulator
