Died suddenly, cranks but no start
 
After concluding 500 mile road trip, filled up with gas and got within half mile of my house and it sputters and dies. Cranks, but will not start. 255k miles well maintained new spark plugs and wires at 225k. Fuel pump? Sure seems like it. How to test any electric fuses that may have something to do with this?
Thanks

How far did you drive after refueling before it died? My first thought is bad gas.

+1 on bad fuel. Fuel pump or possibly the crank sensor failed. As possibilities as to why it won't run. :)

Did it sputter/stumble then die (bad fuel/weak fuel pump) or did it quit suddenly (crank/cam sensor failure)?

EDIT: Does the rpm gauge move or stay at zero while cranking? If it moves then you have a crank sensor signal.

Could also be a clogged IAC, or idle air control valve. It usually acts up when really hot and when idling at a stop light and makes the engine stall.

This morning my neighbor had her 02 4Runner cranking but engine not starting. It ran fine a hour earlier. The tow truck guy took the wooden handle of a rubber mallet and banged on the side of the gas tank several times. 4R started right up and ran.

Sometimes you just have to smack some life into the fuel pump or starter lol

When hitting the tank starts the fuel pump the armature is done. Time for a new fuel pump bad spot on it.

I had a similar experience with a 2.5L V6 Camry. It happened twice, years apart. Both times it was the MAF (mass air flow sensor). Car would run fine then just stop dead; would crank but not start. Garage replaced the MAF and all was well. Second time it happened I replaced it myself.

There are some YouTube videos on testing.

Had a similar problem while on a road trip.
Started running very poorly and stalling shortly after stopping for fuel.
My initial thought was IAC or bad gas.
Ordered new IAC from local Toyota dealer as didn’t want to get stuck on my way back home, 1500 miles away.
Turned out to be bad gas, cancelled the IAC before it shipped out.

Pull codes check PCM inputs.

What kind of black magic stuff is this and does it have to be a wooden handle? lol

The contacts in a fuel pump can wear away and cause the pump to not work anymore. Smacking the fuel tank CAN potentially move the contacts in the fuel pump around enough to work for another time or two. Same concept as hitting your starter with a hammer.
