How would I check for spark? Yes I have checked the fuel pressure and the fuel pressure regulator.

They have spark testers you can buy from parts store for around $15 or remove plug with coil attatched, ground it out and watch for spark. Let me know, thanks.

Replace the fuel filter, if problem still exists verify pump has good power/ground when trying to start if so replace the fuel pump. I'd also make sure you have fuel in the tank. Let me know if you have more questions, thanks.

I dont know if this would have anything to do with it but when I turn the key but not crank it nothing showes up on the instrument cluster except the check engine light. Could something just be unpluged?
Expert:  Dan replied 6 months ago.

That is definitely a problem. Start by checking all of the fuses if good next step is to check power/grounds on the PCM. If power/grounds are good that would point toward a problem with the PCM which would require going to dealer for fix. Let me know how the fuses look or if you have more questions, thanks
