    I recently replaced head gaskets and cleaned everythin in the process including the throttle body 'spider'. When I tried to start, it acted like there was too much compression to turn the engine but battery and starter are good. So I took the plugs out and it turns over great but I noticed there was entirely too much fuel coming out of back (5,6.7) three cylinders, and none or very little coming out of the front (1,2,3) 3 cylinders. I took the upper manifold off to view the CTB Spider and noticed a whole bunch of fuel coming out of the Fuel Pressure Regulator when trying to start. should there be a line hooked up to this FPR or does it work of the vacuum in the manifold?
