All good advice, guys. How do I check fuel pressure? At the rail? Tee a guage in somehow? I'll let you know what I find out.

You can get a fuel pressure gauge at most auto parts stores. If you look on your fuel rail, you'll see a capped nozzle. remove the nozzle and hook the gauge up there.

On a side note: Billboost37 attached a 7 foot hose to his so he can check fuel pressure while you're driving. We found that to be really useful in figuring out my pressure issues.

Let'* remove the cap..not the schrader valve and yes..that extra length of hose is extremely helpful in seeing the pressure diminish as the pump loses the battle.
