97 Concord 3.5 no spark

97 Concors, 3.5 no spark Cam Sensor error

Was running fine after new heads and cooling system (the original issue was overheating... solution was the heater core was plugged and the water goes from pump through heater... bad bad bad). No loner overheated... driven two days. and died moving about 15 MPH

Did the following
* Tested and handheld computer stated CAM SENSOR ISSUE
> Replaced the cam sensor
NO SPARK
> Replaced coil pack
* Tested the coil pack plug (key on light flickered, crank no light)
* Tested the plug for the crank (was 9.2 and ground tested good)
> Replaced crank sensor
NO SPARK

Not sure where to go next ( I have become what my Dad always warned me not to... A PARTS CHANGER)... will follow more procedures in the manual but hoping someone had a magic 8-Ball and could help.

Thanks,

Keeme

So before all this started I told my brother (who is the radiator man) "Hey I think its the timing belt/serpentine". We do all the tests and last thing we do is look inside the cam sensor hole and sure enough... cams not moving.

> Dismantled the cover
> Found broken Pully tensioner
* Dealer 60 bucks our price.
Started the car (ran ok for about 10min)... now hard to start and runs rough... backfires... I think the belt is off somehow (user error most likely or it got damaged).
