RB20 won't start on its own...

[karl wasabi]

Hello all. I've been trying to figure out this problem ALL DAY long. haha. Figured I would try here and see if you guys can help me.

So...I just installed my RB20 into my S13, wired everything up, and tried to start it. All it does is crank over. over and over and over. haha. So, I got starter fluid, and sprayed that stuff in there. Started up with no problem (with a little help from the throttle). After a shaky start, the car will idle just fine.

Another problem I am having is that I have a Nismo FPR. When I try to adjust the pressure to 37psi, the pump goes crazy!!! I have an inline gauge to measure the pressure and when I try to adjust the pressure past 25psi the pump starts pulsating. It goes from like 20psi to 60psi and back. Over and over again, but is fine once the pressure goes below 25ish. Could it be that I have a bad FPR? Would this affect my car not starting on its own?

(Pump is a walbro 255)

Thanks for the help...
