Yeah water in the filter gives it away. Any little bit of water in a 3208 pump the plungers like to stick. Them pumps are pretty simple to rebuild though.

[@kerrygleeson4409]

Some years ago we had an apprentice fitting the same style of fuel tank on new trucks found out he had a bad habit of occasionally dropping the delivery red dust caps into the tanks result when the fuel level was low the dust cap could occasionally attach to the pick up pipe stopping fuel flow engine stops cap would fall of coursed a lot of pain 👺

[@Rx7man]

I know a guy that had a 5 ton truck with a 5.9 cummins in it.. had the same problem.. but it would only happen on one particular stretch of road.. those are tough problems to find I had a similar problem with rust buildup on the bottom of the fuel tank/in the fuel lines of an IH684.. would lose fuel pressure/power.. had to take the whole fuel system apart and backflush it

[@youtubeisawesome2487]

put a pump on a dusted engine lmao check for the filter on the frame next to the tank everyone misses that one also

[@michaelbrown8545]

I'm going out on a limb to predict ether the plungers have seized in the pump elements from water entry or one of the fuel metering sleeve control links has cracked locking the rack linkage in the shut down position. If it failed to start after sitting a longe time likely number one, if it was running and failed at re start number 2. Both very common faults on 3208 sleeve metering fuel pumps but not the inline type on 3204, 3304, 3306. Agree with your trouble shooting methodology, simple stuff first, starting with no smoke no fuel. You get a bit of fuel from the cracked injector lines on crank becase the injector pump elements are still displacing fuel but not enough to overcome the nozzle VOP. Let us know what you found.👍 Cheers mate 🍻

[@ridingwithcharley6821]

If it was that long for the fuel filter, when was the oil last changed 😂

[@jaydunbar7538]

Probably a farm truck, that old of filter may only have a few thousand miles on it. My old cabover had 15k miles on the overhaul that had been done nearly 4 years prior to me buying it from the farmer. Not saying its a good thing to do, it supposed to be done yearly regardless if the milage interval is met, but I can't say I'm not guilty of it on vehicles that see limited use. "I'll get to it"

[@Backyardmech1]

Probably in 2017

[@michaelmccaffrey2731]

What I've noticed here in Oklahoma is that people change the oil but not fuel filters at the same time. They'll wait until it's running bad to change fuel filters.

Awesome video, love watching these. I have the same engine in the same truck. Real love hate relationship. A few years back we had starting issues with it. Sometimes it would fire right up. Sometimes it would crank and crank and crank before it'd start. After chasing our tail around the truck we found the fuel pickup tube in the tank had cracked at the top of the tank. Which was letting air be drawn into the fuel system. Now if I could get that coolant leak fixed...

[@michaelthemekhanical]

Why do VE pumps wear the shaft on an angle so quickly? Apparently Miss alignment... But in my case I think the housing was out or the bearings that were made to suit the pump were... As the pump that came off prior to a new pump going on did not fail in the same fashion... It failed with the Cam self destructing and fragmenting through the pump. Not great.

Had a similar cat engine(can't remember which) play up like this checked stop solenoid and fuel pump banjo guaze but it still ended up being the fuel pump. I couldn't believe the drive gear to the fuel pump isn't even keyed, its just like 15lbft on a taper. Makes me wonder if they slip sometimes and just do this. Idk, just swapped pumps and sent old one for reman.

[@Rx7man]

P pumped cummins 5.9's aren't keyed either, but they're installed at 140 ft lbs and still slip sometimes If this is the injector pump, I'd love to know what's wrong internally.. to not get fuel on all cylinders must be something mechanical

[@brendanrapa8579]

Does CAT make the pressure gauges you use or are they rebranded? Also are they only available though CAT? I’ve been looking for some good quality gauges for a while now and have found it difficult to source those gauges.

[@AdeptApe]

As far as I know they are legitimate Cat. I bought them from my old dealership and have them in about 5 different pressure ranges. They are really nice gauges, are they the absolute best out there, probably not. There is probably some Swiss made, magnetic field gauges out there that cost a fortune, but these work great.
