Question type: Maintenance & Repair

I have a 96 f150 5.0. It cranks but wont starts. Ive
replaced the wire harness and yes everything is
connected. Replaced the vaccuum lines one by
one. Wires and spark plugs. Coil. Crankshaft
position sensor. New battery. Still cranks but wont
start. Today after sitting awhile it started for a
moment then cut out and wouldnt start again. Its
got fresh gas today too. When cranking it back
fires but not right away. HELP!!!!!

check the voltage...and the amperage too~ ECU will actually "brown out" with reduced voltage and become unreliable~ so the black cable connecting to the block also ground the ignition system...if it's weak...or power weak, spark may become not as strong as it should ...so BEEF UP the power to the coil pack...where it's mounted~...possibly will bring the show back in service~

Make sure ur getting fuel pressure to see if it's fuel related. If u got gas, do a compression check before replacing any other parts
