Expert:  Chad Farhat replied 5 months ago.

you have no fuel coming

1- check fuses

2- check fuel pump relay , i sent you the location of it

3- check power to pump at igntion switch on

4- do you hear the pump comes on for few secs when turn switch from off to on , it should come on to prime the system , have u noticed

DTC 542 Fuel pump secondary circuit failure. KOEO Hard Code ................................................. Go to J10 See: Computers and Control Systems > Pinpoint Tests > J10 - Does Engine Start

Check fuel pump realy

The Fuel Pump Relay is located on the left hand side of the engine compartment, in the Engine Compartment Fuse Box.

also sent you the fuse bloc location and fuel pump relay fuse ( letter O) 20 amp fuse , check that too

so if fuse is good and fuel pump relay working and you have power to fuel pump than you need a fuel pump

Hope I was helpfull to you

A Positive rating is Much Aprecciated

so you know pump not running but then we need to find out , why , is the fuse ,the relay or the pump itself
