Hello,

Just so that we cover all the possibilities, have you tried to jump start the vehicle?

First make sure you are getting spark to the plugs.

Then check fuel pump.
This vehicle has a fuel pump control module which sometimes goes bad and makes the fuel pump inspirational. It is located on the floorboard rear passenger side (see diagram below)

If you can't hear the pump come on check the relay then test the pressure to verify.
With the key on and engine off you should have 35-65 PSI of fuel pressure.

Here is a helpful guide on how to test fuel pressure:

You can also test the relay. The relay is located under the hood in the fuse block.

I have attached the diagrams for your reference.

Please let me know of any questions.

Thank you.
