My 1986 Chrysler Fifth Avenue takes 4 trys to start in the morning.
Simply does not start on the first 3 tries. Starts right up on the 4th
try. Starts and runs throughtout the day without problems. Then after
sitting all night back to the 4 crank mode.

New plugs and wires, rebuilt carburetor and distributor.

I think it might be the ECM module (Spark Control Computer) but am not
sure.

Any input would be appreciated.

Thanks
