Get a carb cleaner and spray into the carb or the throttle body on an EFI. Did it start and die? If not disconnect a sparkplug wire or 2 and ground it to the engine -have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel problem, check the fuel pressure to rule out the fuel pump and listen to the injector/s are they pulsing.

Fuel pump and Injector/s checks out-start checking the ignition system-power to coil, coil/s itself, distributor pick-up, control module, Cam and Crankshaft sensors.

If both fuel and spark is present-check the valve and ignition timing, this will lead you to problems with compression and valves opening and closing at the wrong time

Ok battery charged but not getting any spark.I have changed the plugs and plug wires as well as the distributor cap what would cause the no spark condition?

Check for power to coil, coil resistances, distributor pick-up coil resistances, air gap, ignitor, and ignition signal from the computer.

I have decided with the age of the car and the cost of getting the parts and the time it will take to repair the car its not worth it I am either gonna selll it or have it haueld to the junkyard if there are any offers for the car they will be considered
