Oil pressure switch?
My Dad is a little **** about cold startup. He bought a new 2010 F150, and promptly parked it in his garage. They then went on vacation to Arizona, and will be due back in about a week. One of the guys he talked to said that he thought that there was some sort of low oil pressure switch on the F-150 (5.4L) that held spark somehow to let the truck build some oil pressure/flow before starting.
Is there something like that on his truck? He wants to roll some oil before starting it up after sitting for 2 months.
I always just unhooked a DIS or whatever to let the engine turn over without firing on my older vehicles, but I don't know what his truck has.
If not, what can he unhook to turn over without starting?
TIA!

As far as I know the oil pressure switch on F-150s (and most trucks) just work the gauge or an idiot light.
If you want to crank it over to let it build some oil pressure, just pull the fuel pump fuse.

/me shakes head ruefully
What the "friend" is probably thinking of is the silicon anti-drainback valve in the oil filter. It helps keep oil in the motor. Tell your father to get over it, crank the truck, and enjoy it.
