Car was running but sat for a couple of months.Now the engine turns over but won't start. It has gas but suspect no spark getting to the ignition. Possible problem?

    You need fuel, compression and spark. I assume compression's OK. Check for spark, check the fuel pressure with a test gauge. If they're OK, then check for injector pulse.

    ignition control module inside the distributor
    47.00 at advance auto
    just plugs in
    do it yourself
    take the distributor cap off with 2 screws and the control module inside is a half moon black plastic piece with 2 plugins
