I have a 1996 dodge neon with sohc 2 lt. The plug going into the camshaft postioning sensor got screwed up to say. Need to know how the wires go back into the plug. Also the car cranks over fully charged battery but car will not start. Any help would be nice, the book doesn't really show u the right way the wires go in. Thank u rick.

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.

You need to replace the cam sensor connector. They make a pigtail connector for that. Be sure to either solder and heat shrink or use environmentally sealed butt end connectors when you splice in the pigtail. If there is engine oil leaking from the cam sensor connector cavity, you need to replace that too.
Make sure it doesn't have a broken timing belt.
Since we volunteer our time and knowledge, we ask for you to please follow up when a problem is resolved.
