Like the title says I am getting no fuel pressure. It's a 95. I have a walbro 255, 6 an to and from with an aeromotive fpr. I turn the key on and the pump kicks on and I heard the filter fills up with fuel. I pushed the test valve on the rail and fuel came out. I'm not getting fuel to the fpr. Could I have some how mixed up the inlet and outlet on the rail? I'm not really sure if that would cause the problem or not.

how exactly do you have the Aeromotive FPR hooked up? piggy-backed with the original regulator on the oem fuel rail, did you gut the oem FPR, what's you system like?

The fuel set up includes the fuel pump which runs to the filter then to the rail. I disabled the factor regulator. It then goes out of the rail to the regulator and then back to the pump.

How though? also if you aren't running the oem fpr it shouldn't matter if you have the in/out mixed up, though the 'in' is the tube from the filter... I believe the one to the outer section, and the return is comming more from the center. Where are ya check fuel pressure? rail or a gauge on the fpr? little stuff i know, but it's kinda vague if someone's not standing there lookin at it. Also the Aeromotive fpr I have has the inlet on the side, with the return exiting the bottom. try continually cranking also, sometimes it won't prime all the way up first go-round.

I haven't been home since then. I'll be home on sunday to try some shit out. Honestly I don't think I had enough fuel in the tank to fill everything up. haha. I know, I may be a dumb ass if thats the case, and I'm hoping it is.
