NEED HELP FUEL ISSUES 99 Cobra

[Pettinella2005]

Ok everyone....I need to know if this has happen to you cause I'm at my wits end. Suddenly about three months ago my 99 Cobra while driving or even at a stop light will suddenly stall and not restart. Sometimes it will restart for 10secs. and run extremely rough and then die again and not restart. Computer codes are for "Low fuel rail pressure" and "Fuel pump module disabled" Leave the car for a few hours and it will restart sometimes and sometimes it won't. Long story short we have replaced the fuel pump, and two fuel pump relays. Could it be the computer? or possibly a bad ground? I'm at my wits end becuase by the time I have it towed to the repair shop the thing starts right up again and they can't find any issues. Please help, what could it be? Any suggestions would be helpful.

Thanks,
Bob

What pumps did you put in it? OEM? or aftermarket brand?

I had a very similar problem. I had a bad ground from the block to the frame. On your odometer when the problem happens do you get "--------" instead of your mileage?

Had the same thing it was the fpdm

YUP sounds like it's going into thermal shutdown intermittently, could be a bad capacitor on the motherboard...

I had a similar problem, threw the same codes and it turned out to be a loose ground In between the intake and the passenger headlight.

OK I have replaced the fuel pump, fuel pump relay, FPDM, and it still does it but only if I drive it for some time. What else could it be? Bad ground, bad Computer?

What about the CCRM?

 

[Charged99]

Inertia switch? Never heard of them goin bad like that but anything is possible haha

 

[FooteSVT]

Did you check the grounds mentioned Above?

My steps would be as follows....

First off check the ground situation....
Check fuel filter for blockage causing overheating issues...
Replace the CCRM with a known working one...
