Ok, I check the sparks, it dont have any spark when cranking over. When trying to crank over the distributer router dont spend/turn at all (I took off the dis. Cap to check). I also checked the distributer incase it had a broken shaft but as I turn the gear the router turns. Just took off everything to look at the timing belt but its still there and in good shape. I dont get it im very confused right now. Shouldnt the timming belt be connected to the main pulley and the cam shaft sproket all should be turning.

If you remove the distributor cap and the rotor is not spinning then the distributor is broken or the cam is not spinning.

I would suggest starting with checking for compression. This will tell us if the valves are moving in order to build pressure.

If there is no compression then the cam is not spinning. If this is the case, I would think there is an issue with the belt that is not spinning the cam.

This means we need to inspect the tensioner.

I am attaching the info below on this. Please run through this and let us know what you find.

Thanks
