Cranks but no start.......no fuel?

[WahooSteeler]

Truck got parked probably 2-3yrs ago due to various issues, mainly cracked manifold. Been putting off getting it going again due to normal constraints, time and money. My son gets his license in November and this will be his DD until he goes to college. Time to get it running again. So, over the past few years I would start it every 4-5mos and let it idle. Unfortunately time got behind me and it's been well over a year since last fired. Put a new battery in, 4 gallons of new gas and some Seafoam. Lots of cranking and no fire. Several shots of starting fluid and she'd fire long enough to burn that off but no love after that. I let it sit for a few days (and had to recharge the battery) and tried one more time. Same thing, fired with starting fluid but very briefly then dies. On the last try I noticed that the fuel gauge was pegged "full" but I know it does not have a full tank as I purposely let it run low when I last started it so I didn't have a tank full of old gas. Is the fuel gauge incorrectly reading full an indicator my fuel pump finally died? Thanks for comments, suggestions and direction............

Is the fuel filter clogged?

Does the pump come on when you turn the ignition ON?

Eagle, thought of replacing the filter as a cheap first step. Hornbrod, I'll have to try again and listen specifically for it, but I don't recall hearing it before and I had the door open when I went to crank it.

trace the fuel line

Hornbrod, my truck has a hard wired electric fan that comes on as soon as the ignition is turned on so I could not hear the pump humming when I tried it. Need to do it again and crawl under the truck. Hopefully I have some time to troubleshoot this weekend.

when you go to replace the filter, just direct the line into a catch can and have someone turn the key to run.  instant proof if it works or not :D  just be sure to protect your face from any possible splatter.
