What troubleshooting chart did you use? Is the lift pump working? Is their smoke while cranking?
Fault Code: 482PID: P094SPN: 94FMI: 1/18
Fuel Pressure Low - Data Valid But Below Normal Operational Range - Moderately Severe Level.
Engine may not start, white smoke, run rough, or lose power.
ok no smoke means no fuel, IS fuel present at the test fitting on the right of the main pump? You can put a small pick in the center of the fitting to ensure fuel and remove air . If not check and Verify the fuel shutoff operates and there is 12-VDC present at the terminal of the fuel shutoff valve when the keyswitch is turned on. Remove the wire with the key switch on after verifying 12 volts are present and touch the wire back to the post of the fuel shut off valve. It should have an adubial click when power is applied.
Then check resistanbce from the body of the valve to the post the SPEC 6 to 15 ohms for 12-VDC solenoids, if it is not in spec replace.
you should also remove the valve and inspect the internal parts for damage and wear,.
let me know
