The vehicle was in park and I pressed the gas quickly almost to the floor and the engine died immediately. Fuel pump doesn’t prime now.

I checked fuses and relays, replaced relay.
I checked the fuel reset button
I disconnected the battery
I replaced the fuel pump

Fuel pump still doesn’t prime.

No codes are being thrown.

Fuel filter is “lifetime” and in-tank from what I’ve seen.

Doesn't prime?

Does it work at all? Does it build pressure when cranking?

Do you know how to do electrical testing?
Can you read a wiring diagram?

Bryan? Any luck yet? If it doesn't prime and wasting $$ on a new fuel pump didn't work, neither did any of you testing it was even a suspect reason. Pumps (keep wet* with something) should work on a bench without a vehicle around for a second if given power and ground.
*Note on pumps of liquids: Most need the liquid to lube them or burn up "impellers" right away for pumping but motor would still work.
Fuels require tolerant impeller ways are still only driven by a motor,

Re: Fuel pump doesn't prime	Sign In

just about any car w/ Fuel injection if you put your key in the ignition and turn the key to the ACC , NOT START , just ACC you should hear the faint sound of the fuel pump for a few seconds.

whats a fuel reset button?

so yeah let us know what happened ...don't keep us hanging
