Talon Won't Start

[JET]

Alright, I am just about stumped on this one. I have a few more ideas, but wanted to see if anyone else can think of something. The new talon I got runs great once it starts, but it is very hard to start. Now it just won't start at all. If you pump the hell out of it it will pop once in a while, but that is it.

I have replaced the whole fuel pump assembly, FPR, ECU, and plugs. It turns over fine and there is spark. One odd thing is that the fuel pump continuously runs. You can hear the fuel going back to the tank, so there should be fuel pressure. It doesn't shut off once the correct pressure is achieved like it should. There is a module with 2 relays in it that run the pump that I would like to check, but it should still run fine as long as the pressure is there.

Even if a coil pack is bad it should pop once in a while, same with a fuel injector, so I ruled those out. The wiring harness by the ECU has been messed with some. I think it was mainly to put the alarm in it, but I am going to check that out. I have also noticed that the stock boost guage is acting screwy. It will go all the way negative after you stop trying to start it, sit there for a few seconds, then go to 0. I also got it to go all the way to 14 psi and sit there when the key was on and not trying to start it. There is no CE light. I will be working on it more this weekend, but I wanted to see if someone could save me some trouble.

Thanks!
