I would check the actual fuel pressure to be sure the pressure is correct.
Key On, Engine Off .................... (approx.) 338 kPa (49 psi)
Note: Using the DRB Scan Tool, access ASD Fuel System Test. The ASD Fuel System Test will activate the fuel pump and pressurize the system.
Caution: When using the ASD Fuel System Test, the ASD relay and fuel pump relay remain energized for 7 minutes or until the test is stopped, or until the ignition switch is turned to the off position.
Are there any codes stored from the check engine light?
I would also check the compression to be sure there is nothing wrong internally. You need 140-160 pounds.
