Zach, you're right. Not sure if I can test the regulator... but it's worth a shot.

if the pumps are backwards there wouldnt be any fuel in the rails, at least not in my experience (it happened to me before rewiring ****)



the guy who suggested checking the FPR adjustment, good call... right when I read that it felt like an anvil landed on my head.



so 9b3 did you adjust the FPR?

Yeah... I did. Nothing changed. I've GOTTA be missing something somewhere.. My gut tells me it's the ECU, as I'm 99.99% sure the rest is right. I've spent so much time making sure of it... DOWN TO THE WIRE if you know what I mean... This is SO frustrating..



If it *Could* be the ECU, where would I look? Anyone familiar with these things? I refuse to go the the club, so I'm badgering you guys.. https://www.nopistons.com/forums/pub...#>/biggrin.png



The settings *seem* to be right... Fuel is there.. Spark is there.. In the maps at least.. God I wa't this thing to go! I's KILLING ME!!!



Tell you what.. I need to go get another fuse..



I'll start ALL over again when I get back..



I'll start with FUEL. As that is a KNOWN problem, and can be worked outside the ECU.. Then I'll go from there.. Might just reverse the wires on the pumps for the hell of it. I figure with 2 Walboros at 12V and -6 all the way around to a wide open regulator... I should see some ******* pressure!!!!!



Thanks again guys.. I really hope I can meet all you guys some day!

I know when I first had trouble getting my car to start it was also fuel related. I was running an Aermotive A1000 and it does not have a schraeder (sp) valve on it, so after you turn the car to the on position and the fuel pump primes the system, it will not hold any pressure, it simply falls back to zero unless it is being cranked on. I had the wrong fittings going into the regulator and it was blocking the return line from recieving any fuel. Are you sure you are using the Boss style fittings and not the beviled style of FPR fittings? That would stop pressure from reaching the regulator which would more or less block the system from running. Can you remove the return line and turn on the system to see if you are getting any fuel to the return line?



Just get a noid light to check if your injectors are firing. But to see 0psi at the FPR is wrong...you should have fuel there as soon as the car is turned on, it should prime and deliver enough fuel to fill the system. Are you using any relays in the wiring system?

If you are running a PFC, it is not the ECU, it will start with base maps, no problem.

the FPR needs to be closed for fuel pressure, not opened.

Justin, you need to CLOSE the FPR. Close the FPR to gain fuel pressure

would there be a reason why you would keep popping fuses?

I'm also running an Aeromotive FPR.. I know there is fuel IN the FPR.. However, I'm not sure if it is returning to the tank.. I pulled the return line at the tank and there was nothing in it.. But the feed line was nice and full and blasted me in the face LOL. I'm REALLY confused as to why I get no pressure readings on the gauge.. I might yank it and see if the port is blocked or something..



Next step is to remove the return line at the tank and turn on the pumps.. I'll know if pressure is going through the system then. There isn't anything in between the regulator and the tank on the return line that would cause blockage... So I'll know if the regulator (Or fittings) are the cause..



Question: If the fuel isn't returning, that doesn't mean the car won't run does it? It'll just flood real bad right? I know there is pressure to the regulator... Just not sure where it goes afterwards..



'Nother dumb question: What's a noid light?



Nope, no relays in the wiring... Other than the stock relay which is jumpered to 12V constant..



Thanks VERY much for the help. https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...#>/biggrin.png https://www.nopistons.com/forums/pub...#>/biggrin.png

If you used anything like teflon to seal the gauge and fuel line threads, its very possible that it could have come unraveled and blocked the ports...ya never know. Not too sure about the whole non-return situation though.
