Awesome! Thank you! I’ll have to watch the videos and order the stuff, and then wait for a Saturday or something to pull the pump apart. The miles might be somewhat off, but I know the truck has less than 150,000 miles. When the P.O. swapped the 47rh in he didn’t get a different adapter and just put the sensor straight into the transfer case. Based off his saying the transmission has about 30,000 miles on it I’m probably actually around 132,000 or so. I now have a adapter from PATC on there so I am only off by maybe two miles per hour. I don’t understand why anyone would ever run alternate fuels in these trucks. They were meant to run on diesel, not concoctions of used fluids. I’ll definitely have to do some reading and video watching to get to where I am comfortable enough to reseal this pump. Looking at the reseal kits there are a lot of o-rings. Maybe now would be a good time to locktite my front seal on so it doesn’t ever come off. I’m sure these pumps aren’t too bad, I just don’t want to loose any parts or get anything out of adjustment and have to send the pump off anyway to get flow tested.

I don’t think I’ll get away with the kitchen table even though I’m not married. I’m still in high school, so I live at home and I’m sure my mom would not approve. The bed of my truck is probably as good as it is going to get. That’s when I find time to do it. I’ll probably just lay a piece of plastic down in the bed of my truck and put everything in labeled baggies. Should stay pretty safe since I have a shell on the truck. Maybe I’ll have to get out one of the spare folding tables and use that inside.

I guess it is possible, but I don’t see how that could happen. I had the tank cleaned, and it was spotless inside when I put it back on. The only place I can see stuff coming from is stuff that was inside the injector lines before and has recirculated. I thought it would have been burned out by now, but I guess 1,000 miles isn’t enough. Don’t EVER run WVO in your truck!!!

Change your fuel filter, install a cheap mechanical gauge in place of your filter head bleed screw, and report back.

So today I fiddled with the pump some more to try and fix my no start issue. I pulled the throttle lever off of the throttle shaft to access the back side of the fuel slide pin that is stuck. So I did that and removed the little cover that is on the back side of the slide pin. Using a mirror to make sure there was not anything in the way I used an Allen wrench to push on the pin. With a little pressure it popped back into the bore hat the fuel cone sits in. So i then grabbed a small screwdriver and popped the pin back the other way. I moved it back and forth several times until it felt like it had freed up. It never was all that stuff, but it freed up some. It now moves easily back and forth. Not too easily, but it moves smoothly beside the little bit of a popping action. I was hoping that this would make the truck start, but when I went to start it it just cranked. I didn’t crank it for real long since it was past 9 o’clock, but it definitely didn’t magically fix it unfortunately. Is there some spring that hooks to that pin someway? Is it possible something came unhooked down inside the pump that is not allowing it to move that pin anymore? Right now when I move the throttle lever it does not pop that pin out like I’ve been told it should. The pin did not appear to be rusted or even dirty when I looked at it after popping it out. The only thing that I changed before the whole no start thing happened was pull the fuel pin out and replace the diaphragm. I am about to just bite the bullet and get a new pump as I really need this thing going again. Anyways, that is what I did today.

Yes. I have even tried gutting the solenoid by removing the plunger and spring with the same result. Trucks starts with one small spray of starting fluid and stays running. It also shuts off just fine. I just can’t figure out why the sag slide pin that rides on the fuel cone won’t pop out when he throttle is moved like it is supposed to. I have talked to a couple other people with these trucks that had a not start issue from that slide pin getting stuck too far in. Maybe I just need to suck it up and get a new injection pump.
