Hello,

Here is a guide on how to check the engine wiring diagrams in a guide and the engine wiring diagrams (below):

These diagrams include the PCM and all related sensors to run the engine including the fuel pump and for both the four and six cylinders in case anyone needs them.

Let us know what happens and please upload pictures or videos of the problem.

Cheers, Ken

First thing you must do is scan for fault codes. I would not recommend just randomly performing resistance checks on circuits, that would be an extremely inefficient way of diagnosing.
Sometimes during swaps connectors are plugged into the wrong location, ground wires are left loose, etc. To help isolate which circuit is faulty you must scan the vehicle.

Does the vehicle crank?

It does crank, I will check for trouble codes first.

Ken,

Can you provide a source for the PCM diagrams provided in your earlier post? I am trying to troubleshoot cooling fan issues on my Mazda Tribute and the ones you have posted are fantastic. I have not been able to find anything like them online.

Thanks, Jared.
