I bought a fuel pressure gage from a Checker I believe (any auto parts store should have it about 50 -55 dollars). I have fuel injection so I unscrewed the small cap off of the fuel rail, under that is the pressure check. It is about mid way through the fuel rail. I attached the gauge and started the vehicle. 31 psi is normal. If you remove the vaccum line form the fuel pressure regulator the psi should jump up to 39.

So you think your tough?
