This car will turn over, no spark or fuel to plugs. Have changed crank positioning sensor and the cam position sensor. Switch computers exact numbers from a running car. Still no difference. My Haynes manual does not show where the power to the computer comes from or which relay it might be any help from you would be great.

Hello,

It does sound like you might have a wiring issue and the engine control module not getting power or has a short.
You might have to trace wiring to find out which one is shorted.

Here is a helpful guide of how to check wirings effectively:

I have attached the wiring diagrams for the engine controls.

Please let me know of any questions.

Thank you.
