I’m once again here asking questions about my weird clacky 83 idi. This time she died on me. Story time, I guess.
It started out this morning after I decided to retard the injection timing (someone else advanced it too much) and add 1.5 flats to the fuel screw. That all went well, it fired up okay and idled for probably a minute loping a little but it’s always done that. Then it just stalled. Huh, weird. Went over and cranked it for a couple seconds aaaand… nothing. Decided to crank it for a little longer while flooring it and it eventually fired up and absolutely smoked out my neighborhood, ran like garbage, and died again. Did this dance of cranking, running, and dying a few times and then it eventually just kept running and smoothed out to normal. I chose to ignore that figuring that it was just air from having the pump open.
Unfortunately, on my way to bring a load of scrap metal to the scrapyard the truck started losing power suddenly and lost all fuel. I continued rolling in 4th with my foot to the floor and probably 10 seconds later the power came back, and then gone, and back a couple times. About a mile later it completely died. Did the same thing where it would run and die over and over. I was pissed at this point so when I eventually got it to fire again I just held my foot to the wood instead of throttling it. Lo and behold 10 seconds of governor seemed to fix it. Drove back home, no issues, good-ish power.
Got ballsy and tried to go to the scrapyard again because even though I knew something was wrong I decided to go anyways. 4 miles later, dead. Really dead this time. No matter what I did it wouldn’t run longer than 3 seconds. Waited 30 min for my friend to help. Tried to crank it up, still the same after sitting. Decided to use the starter to turn the truck around in the road, truck started and ran fine, booked it home to where it sits now.
Over the last few weeks I’ve been noticing a slight loss of power at full throttle, lots of noise not much power. I don’t really know what the issue is at this point but I’m suspecting I might’ve bunged up the injection pump or the lift pump is weak? I have another questionable injection pump that I could try installing if needed. Fuel filter is a month old and I have fuel coming out the schrader valve when cranking. Shut off solenoid sounds like it’s working properly. Return lines aren’t leaking and I haven’t had issues with air intrusion in the mornings. Maybe someone else has experienced something similar because this is unlike anything I’ve dealt with. Maybe I’m just overlooking something
