    It ran fine when parked, but when I tried to start it after it had been sitting for a month or so it would crank fine but didn’t start. After some troubleshooting I discovered I didn’t have spark. Replaced the coil cap and rotor and now have spark.

    When I try to start now it cranks, but acts like it’s out of time by cranking hard. I have double checked the wires on the plugs and cap and they are correct I believe. Clockwise I have 1,8,4,3,6,5,7,2. I pulled all the plugs out and they look dry with no to minimal carbon deposits on them. I’m quite sure this is an electrical issue, because when I crank the engine with the throttle body injectors unplugged it cranks like normal.

    Any ideas on where I should be looking to troubleshoot and fix this problem are appreciated.

    First ..triple check your ignition wiring.
    Second, confirm mechanically the engine timing is correct.
    Next try using starter fluid if the engine starts and dies your looking at a fuel delivery issue
