Well the following weekend I drove the car roughly about 70 miles @ between 60 to 70 mphs. Well when i got near the paint and body shop to get an estimate on what it would cost to have the entire car repainted. My fuel system shit the bed again. The fuel rails wouldn't hold any fuel pressure. The same problem i have been having for now about 4 or 5 months maybe longer. Well I towed the car back home and I'm back to square one again. I purchase the BBK aftermarket fuel rails and still same problem. It would idle for about 2 mins then loses pressure. Purchase the areoequip fuel regulator installed it in the engine bay to regulate pressure soon as it leave the rails to maintain 60 psi. Ran a return line from the regulator back to the tank. Still the same problem!!! At this point i almost gave up but a friend asked have i checked power to the fuel pump? Well at the time I told him the vehicle starts and runs so i have power. The power runs from the battery to harness into a relay then to the tank. He told me just straight wire your fuel pump to the battery and see what happen hell I didn't have anything to lose I have at this point 2000 in fuel parts trying to fix this problem. PEOPLE it has been power the entire time something about that relay was stopping power or allowing some power to a certain point or something. I drove the car Saturday until Tuesday when I had to check back into my unit and haven't had a problem at all. I have been WOT multiple times. Long distance cruising trying to cause a problem and nothing. I spent 2000 and i really believe something was wrong with that relay the entire time. After giving it all the hell it can handle for those 4 day i know i got it solved this time. I'm calling HOTWIREAUTO.com tomorrow and asking whats the cause and effect if I continue to bypass that relay. When i swap the relay to other location to determine that's it's faulty it worked fine but if I run the fuel system with that relay involved it's work for a short period of time then problems after problems.

Happy to hear that you're getting it all sorted out. I'm about to order a harness from hotwireauto...was it the fuel pump relay in their harness that was the problem?

Yes it was I still haven't got in contact with them to ask why the relay is doing this.
