i bought new fuel filter spark plugs. wires. optispark. ignition coil and ICM. egr valve. pcv valve. mass air flow sensor. sitll no start. and i got 42 psi of fuel when i tested it. but only when i connected a wire from battery to prime connecter i got a reading...im guessing there is fuel in the lines. but it still doesnt want to start. could it be the pcm???
