Truck will not crank?
OK so here it is. At first I thought it was the fuel pump, replaced the fuel pump truck ran for ten min. Then quit has not cranked sense. Not getting any spark from the coil is what I have diagnosed. So far I have replaced cam sensor,crank sensor,rotor button,cap,computer.

    Are you saying the starter motor cranks good, but engine won't start? Did you check primary voltage at the ignition coil, pink wire. Should go hot when you turn on the key. Any applicable trouble codes?
