We replaced the coil pack...that was not it. We're going to check the cam and crank position sensors to see if that is it. We need location of these to parts on a 1998 plymouth neon, and any other posibilities that it might be. the way we know there is no spark, we used a timing light.
engine will turn over. there is still power.

Make sure battery has a full charge and battery connections all good.
If it cranks good but won't start, have a helper crank it while you visually check for spark at the spark plugs. If spark everywhere, use a gage and check proper fuel pressure and fuel injector pulse.
If you having a problem with more than one system, I want to check for rpm signal, that usually comes from the crank sensor. Not sure why you replaced cam sensor? I always want to check sensor wiring circuits before replacing anything. Don't replace anything unless your testing points in that direction.
if your valves are bent ,then i take it your timing belt has snapped .which means your camshaft can not turn ., so you can not get a spark at the plugs.if it was the old distributor you would have been able to check the coil with a spark plug tester the trouble is with a coil pack it is controlled by both sensors and your ECU but due to the camshaft not turning so your camshaft position sensor can not tell the ECU to fire the coil pack.
It could be a bunch of things, any oxygen sensor, cam position sensor, crank position sensor, air inlet temp, any of these things will trip off the engine light. You have to get your car to the parts store and get the scanner on it and see what codes come up, you can replace parts forever and not hit it. Save your old parts, they are probably still good. Coil packs are expensive. Check it out, hope this helps.
On this type of vehicles' "Diamler-Chrysler" for some reason the Crank and Cam sensor go bad at the same time but it will still tell you its either one or the other, if you are still getting the Cam sensor trouble code, try replacing the Crank Shaft Position Sensor, I just had a Dodge vehicle with the same problem but in reverse, it kept saying Crank Sensor but it turned out it was the Cam Sensor. Good Luck.
Sounds like it is either a bad coil pack, cam position sensor or crank position sensor. The coil pack delivers the spark to the plugs and the 2 sensors tell the computer when to tell the coil pack to spark.
