Good evening,

Is the theft or security light on? It could be a security issue. If you have another key, try that.

Is the check engine light on? If so, do you know the codes?

Okay, the 2195 and 453 possibilities are attached. Do you have a scan tool to monitor the fuel system? Both codes are fuel related.

I would start by checking the actual fuel pressure to be sure the pump is good.

I put a new fuel pump and a new fuel filter in already. How would I check the pressure?

I attached a guide for you for this. You have a valve on the fuel rail for testing the pressure

I attached a picture of the rail and circled the valve you attach the tester. If you do not have the valve, then you have to read the voltage of the pressure sensor located at the same location. I attached a chart that tells you the pressure with the voltage.

Thanks for you help I found a line from the motor to the top of the throttle that was broken and was allowing only air into the throttle. I replaced it and now it runs great.
