I have come by a 95 3.4 lt it has set up for 3 or 4 yrs and the fuel pump and old gas are no more and have replaced the pump and filter. got gas to the maifold but it does not seem to be very high psi. it does run and start with gas poured down the elbow. acctualy runs great while choked with my hand. I feel that maybe the injectors are stuck. is this possible? and can i check the psi at the return?

 

Have you considered a vacume leak?

 

Test the fuel pressure with a gauge. See if the pump is putting up enough pressure & that the pressure reg is working properly. If they test OK then look into getting the injectors cleaned.
