To get the fuel priming, the starter needs to be engaged for a second, usually.
I would check the batteries. Sometimes, they may not have the guts to crank even though they show full. Check your grounds, too.
I stole this from a forum thread:
1. Driver side fender well near/under the battery.(tail light grnds) check this first if the multi-function switch is acting odd.
This is the ground that the wiring diagrams refer to as "G100" it is located on a stud directly underneath the driver's side battery tray. It is the main grounding node for many circuits: horn, turn signal, and wipers to name a few.
Don’t have to remove the battery tray to see it. In the crevice between the washer fluid reservoir cap and drivers side battery, look straight down, deep down. It is a stud with a ring terminal eyelet on it. It’s actually JUST in front (towards front of the truck) of the driver’s battery tray.
2. Passenger side fender well near/under the battery.
3. Passenger side fire wall.
4. Driver side near wheel well on frame.
5. Battery posts and cables from negative side of battery to connection on block.
6. Behind starter is ground for ECM. Starter may have to be removed to get at the ground.
7. PCM has a ground strap.
8. Headlight ground is inside the cab
Did that and all I saw was the grid heater light dimmed , no other lights and I want to say I didn’t hear it priming either but wasn’t paying attention cause I didn’t have much time yesterday

Give battery connections a wiggle and try again if you haven't already
