Long crank, now no start

Dena6.4 · Oct 26, 2014

Okay, so this morning when I started the truck it cranked about twice as long as usual before starting. Started it up again to run to the store and it did the same thing. Went to leave the store and it long cranked then started, ran for about a minute and died. Now it won't start up normally. If I leave the key on for about 5 mins then try to start it will start up then shut off after about 15 seconds. No codes on the cts.
LPFP maybe?
Any ideas?

Can you hear the lpfp running with the key on?

Nope..parked right by a noisy main road and by myself but still think I should be able to hear it

Put your hand on it, if you know where it's at, and feel it vibrate or not. Then check voltage.

Pump wasn't running. Shutoff switch by passenger door was tripped..reset and it's running but still no start

I've cycled the key on and off thinking it's got air in it but no luck

Running fine now..guess I got all the air out from the pump being off..no clue what could've tripped the shutoff though

The shut off is an enersia switch (spelling?) it trips when it sees a certain force, I seen them trip before from people doing donuts

Yeah just weird the truck ran for about 50 miles after the long crank problem started..I would think it wouldn't keep running at all with the pump shutoff..it starts right up like normal now

i've seen a couple 6.0s trip for no reason. They must be somewhat sensitive.

The truck it tripped on that I saw was a 6.0 doing donuts

We had someone tow a 6.0 in for a no start. The first thing I saw was a spare tire on the right front and knew the switch was tripped. I've even kicked the kick panel on a buddys truck to screw with him. Sometimes the switch is too sensitive.
