I have spark and Jeep will fire with intake cleaner or the like sprayed into throttle body. Fuel pump comes on with key and runs for a few seconds and shuts off. Turn key back on and pump runs for shorter time and shuts off. Seems fine. I removed the fuel filter and it is not clogged and pump runs and pushes fuel out of the "out" side of filter when key is turned on. I still however have no pressure at the fuel rail and if I disconnect fuel line at the rear of fuel rail (which I think is the "in" side) no fuel comes out. Ideas? Oh, yeah...new CPS was my first part replaced when Jeep wouldn't start the first time.
