I have no spark on two coils and spark on two coils. I moved the coils and ones that didn't spark now spark and the ones that did now don't. The two that do spark is 1 and 3 and the two that don't is 2 and 4.

This means all the coils are good. What you need to check would be the wiring circuit and the Engine Control Unit.

Did you check for trouble codes?

Run the engine and recheck for trouble codes. They are the key to what could be the problem.

Ok so the two coils that spark are weakish and orange. I really need to get this car running again soon. I bought a scan tool and so far it is of no help.

I just found out that the car over heated and the belt broke. Replace the belt let it cool and that's when the problem started. It cranks fine. I do get an rpm reading but it does not start. It has 4 cop 2 which won't spark and the other 2 do spark. When I unplugged the cam sensor all 4 sparked weak and slow. Replace the cam sensor with no improvement.
