If you have spark then the crank sensor is ok. Is the theft light on or flashing?

We need to start with checking for codes and see what is there.

Here are a couple other guides that will help with this:

Clearly you have already tested the injectors and are not getting the command to fire them. This is the PCM is not grounding the circuit to open the solenoid. So this is either a PCM issue or another system that is telling the PCM that it is not okay to fire the injector.

So hopefully we have some codes or the theft light is on and we can go from there. Thanks
