I have a 2015 Ram 2500 4X4 6.4L, I ask for help from others on this site and always turn to either the fuel cap, ESIM, carcoal canister, some fuel model under the hood, replace fuel tanks and on and on.
I had all the codes that everyone entered that didn't rkettell anything excpt gas cap or ESIM. I had repleced 5 fuel caps both OEM and aftermarket plus the ESIM accoring to people that test and certified parts claims they are the same.
Know back to the no fuel problem 20 Years earlier I was certifed ASE technician so this wasn't new to me before my accident that doesn't allow me to ly on a creeper, 4 disc fused in my neck so I have migrains by putting pressure on my neck.

Life sucks and the migrain yesterday was worth the hell I lived thr the rest of the day and all night.

I am sure older car machanics know that your fuel take has to vent to be able to fuel anything. I pressed up the tank and could here a solenoid was activating, the soung was comming under the truck I removed the ESIM it functiomed properly, the charcaol canister was good I left the canister and ESIM off the truch.
With the fuel valve out of the system, charcoal canister and ESIM off the vehicle and still never would allow fuel flow into the tank, I was either going to pull the fuel pump before that I goy thing about old fuel systems before our vehicles put more contaminant in the Ait all we needed is a vent vale. After making sure the vacumn line weren't pinched I pressured up the tank the ait didn't go to the tank though nither xent on the tank wound allow air, if no air is coming from the vent no fuel will go into the tank'

There is a small Fuel Pressure solinod if you tak to Ram part people are required to replavr the entire Vacumn line assembly. After removing the solinod I decided to see if air would go to take that we be NO, I have an adapter that fits the line connector the plud vacumn system under 150 psi blew out what ever was lodge into the vent lines, fuels on high no problem, scanned and cleard the system.

People wth fuel issues this fuel solinid is connected to filler neck vac line it has a wire plug on it, it is available thru any auto parts stores Ram is full of it. Not sure uf it would mess with smog test ? I would take the tube off the metal tube and crank up the air prssure and not install new one unless you wany to have more problem 150,000 more miles ?.

So.. are you saying that blowing out that solenoid 'fixed' your problem? Or didn't? I will agree that there are some systems on Ram (and other) trucks which never EVER used to be problems forever (fuel delivery/return system) ...but can be needlessly frustrating and complex these days. Just to save a few gas fumes (while oil companies blow off methane day and night at oil fields across the country).

(sorry...looks like you had a lot of auto-correct going on ..kind of hard to follow 100%)

It would be helpful to have a full diagram of every system connected in any way to the fuel tank on my truck. The only one they had at the parts counter at my local dealer showed a generic diagram (according to the counter man) of the tank, it's difficult to know exactly where to look if you can't trace all lines and fittings and determine the function of every device involved in venting the tank. I had filling issues with mine for a couple months then it cleared up for over half a year before rearing up again. Yesterday I trickled in one gallon before having to continue on, then came back 3 hours later and it filled like there was never an issue.
