Trouble starting and idling....

Well I finally was able to get my car running earlier this week.....it took along time to get it started but she eventually did. It was idling then for approximately 10 minutes but then it began to overheat some so I shut it off.

Well I am trying to get it started again so that I can try and fix my overheating problem but my car won't stay running long enough to try and do anything. Most people won't have this problem, but a few of you with an Aeromotive A1000 FP may be able to help me. I know it does not have a schrader valve on it so fuel pressure is not help constant in the lines once the pump quits running. I can not start my car by letting the pump prime and then starting it. I have to start the car while the pump is priming and then it will stay running anywhere from 1-20 secs. before it dies.

I am running a -10 Feed line into a pair of -8 lines to both rails in parallel. Then a -8 return line from both rails to an SX FPR, and back to the tank via another -8 line. I have no evaporative system on my car, I doubt that matters much, but just in case, I am letting you know.

My question is about fuel pressure and why the car won't stay running. Could I have too low of pressure, too high of pressure, too much fuel coming in via my 750 pri/1680 sec injectors, not enough fuel, etc...? What would cause my car to start only when the pump is priming and only run for a few seconds now.

I don't know what else you need to know about my car, it has a brand new ported motor in it, we have used ATF to start it, we have unflooded it a few times, I am just trying to figure this out and I am sure someone knows what the problem is and possibly how to fix it.

Thanks,
Scott
