While changing the alternator I had someone put the battery in and they hooked it up backwards. So far I replaced all relays, plugs, wires, cap, roter, ignition module,fuel pump and filter .It will only run for 3-5 seconds .

  1. You will need to determine what is is not getting when it will not run.
    Is it missing fuel or spark and or injector pulse. See if it will stay running with starter fluid. If it does, you know it is fuel related and can concentrate on that area.
