The wires, plugs, coil pack, and intake gaskets have now been changed, compression on all cylinders are within 149-151 psi and fuel line pressure is 45psi. The total repairs are at over 1000$ so far. Now I'm thinking cam and crank sensor, any ideas on what might be a probable cause. Any suggestions are welcome, Thank you.

After trying the crank sensor if that does not help from past experience
I would say it is the computer or burnt valves.
