that’s what’s a bit weird. My fuel system is spotless. Tank looks brand new. I think starter fluid was used too long because of the algae damaging a cup on the injector or more.

Flordianson, thanks for the reply. It was about a 10”splatter of a wet gooey algae mess on the floor. Pic attached. Truck starts up perfectly for hours after it warms up. I haven’t checked fuel pressure yet because I’m not sure how to fix it if it’s low or wrong. I did buy a sight glass to...

Wanted to update this for the future for people who search - Truck still isn't completely fixed - Found a black algae substance in the fuel filter housing. When the truck was running nothing was coming out of the fuel filter bleeder on bottom so I poked it and it shot a bunch of junk out. I...

After more diag I agree completely truck is loosing its prime. Check valve moves super free. Put 5 pounds of external air in tank and it open end shot fuel right out. pressure tested feed line and held pressure all night. when I hooked up external air the tank would always make a noise of...

Update - Found a check valve in my spare parts - didn't fix the problem. I see m35a3's don't have electric pumps and use a mechanical transfer pump... Does it use the air system that's plumbed into the tank as a "pump" ? Could an air leak in that line, therefore not pressurizing the tank, cause...

Going to look into a check valve - Absolutely no reason to believe engine damage has happened at this point. It runs too well with no smoke when warm. Anyone know about what electric pump to use? I see there is one available for a m35a3. I find it weird mine doesn't have one, but just a normal...

frank8003 and 98G, Really? Come on. Duh. That's why I'm here trying to figure out what's broken and to replace it.

Thanks for all the excellent replies - I went through all the suggestions step by step. To clarify the truck always starts, but its a pain to do without starter fluid. My lines fuel/return have no check balls in them or any associated fittings. Lines had residual fuel in them but didn't have...

Great question I should of been more clear. It gradually began firing harder over the years. I added a new fuel filter with no change in ease of startup.

Tried to search and the TM... no luck - A3 Cat 3116 motor. New fuel filter, at any temp the truck is equally hard to start. (0 -100 degrees ambient same issue) Need starter fluid to kick it off then blows white/black (95% white) and doesn't fire on all cylinders until its warm. It starts up 2-3...
