95 will not run

I have a 95 safari ( VIN W. CMFI Fuel Injection)and it will not run corectly any more. It Started as the van would not want to accelorate. It would only want to go about 35mph act as it were starving for fuel.Now It will not start most of the time. If I give it a shot of Fuel in the throttle body it will start and Idle Ok. If you give it throttle too quickly it will die out like lack of fuel. Fuel pressure is good 55-60 psi. (new Fuel pump) New Plugs Wires cap And Rotor Great spark. Any sugestions? :banghead:

What is the fp as it falters, did you replace the inline filter?

Yes New Fuel Filter And Strainer. FP Withinn Specs all the time.!

Ok tough to start, how about the loos of power at 35, also did you check the coolant temp sensor for proper temp inputs to pcm on a scanner?

Fuel pressure must maintain a MINIMUM of 60 psi or driveability concerns WILL be experienced. With the key on and the engine off, fuel pressure must not drop below 55 psi after the fuel pump shuts down.
