It seems like there's no spark.

Good afternoon,

I attached some guides on how to check for fuel pressure, spark and compression.

Can you hear the fuel pump run when you first turn the key?

Okay, I would test the actual pressure.

FUEL PRESSURE
1. Ignition "OFF" for 10 Seconds.
2. With ignition "ON, " engine "OFF" and fuel pump running, pressure should be 333-376 kPa (48-55 psi).
For additional fuel pressure testing, See: A L L Diagnostic Trouble Codes ( DTC ) > Related Tests, Information and Procedures > Diagnostic Chart

I attached the location of the test port for you to test.
