Hyundai Mechanic: David Craig, Auto Mechanic replied 1 year ago

you are talking about relays then......

Ask Your Own Hyundai Question
Hyundai Mechanic: David Craig, Auto Mechanic replied 1 year ago

you're going to have to check the fusible links ad all fuses in the engine compartment. check the battery positive wire going into the fusebox. check any smaller ground wires that may have been damaged on top of the radiator core support, right and left fenders inside the engine compartment

I assume you want me to jump a wire across the plug how do I identify theese numbers are they on the plug? Should I just replace the relay?
Hyundai Mechanic: David Craig, Auto Mechanic replied 1 year ago

ok. you will have to pull the fuel pump relay. with your meter, probe each position of the relay base til you find 12vdc. no other position should have voltage. then turn the key to the run position and look for 12vdc on another position on the relay. you will now have 2 positions with voltage and 2 without. take a jumper wire and jump from one of the positions with 12vdc to one without, and listen for the fuel pump

Ask Your Own Hyundai Question
Hyundai Mechanic: David Craig, Auto Mechanic replied 1 year ago

possibly stuck

Ask Your Own Hyundai Question
Customer reply replied 1 year ago
If relay was stuck closed would not fuel pump run all the time even with key off instead it is not running at all. It seems there should be hot wire that is only hot when key on to signal relay to close and pump and other things to operate
Hyundai Mechanic: David Craig, Auto Mechanic replied 1 year ago

you're correct. im am overthinking this. its been flippin 9 days.
