alright it sounds like your on the right track but still something doesnt seem quite right to me.
Im deffinetly with you on the fuel issue but you said it was at about 2400 rpm and it wasn't pulling worth a crap and egt's were low. Now im not a cummins guy but if the motor's running at 2400, it should be getting good fuel no?? im not doubting you guys im just really interested :pca1: |
A fuel plate won't help with the defueling. That is controlled by the govenor. You'll need a GSK kit.

My 12v will get up to 2400 no problem but the fuel pressure drops to almost nothing, well below 10psi on my gauge. So yes it has fuel but not necessarily enough fuel.
Put a fuel gauge on it, I was amazed my truck was still running when I saw what the psi was.

sounds like a tranny problem because he said it was at about 2400 rpms and only going 20 mph, the engine might not have had the power but it was turning enough rpms. and if the engine has no load on it then its not goona have a whole lot of heat in it. sounds to me like the torque converter is toast. either that or the valve body didnt let it shift to the next gear so it could go on. jmo

Then shouldn't it have cooked the tranny fluid.
|
smell the tranny fluid to see if it smells like burnt toast, then pull the tranny pan and see how much debris is in the bottom. with those rpms and only going 20mph that fluid should be a stinking bad!!!!!!!!!
|
The combination of very low EGT's and he said the tranny fluid is still fine is why I said it's gotta be fueling issues.

about your 12v with no power pulling i would do a built trans i went the cheap route at first and broke my imput shaft but i now have a full builet trans with all three shafts converter and valve body flex plate and lock up controler the lock up is the big deal because the early years have a gruonding issue and wont lock up thats what mine was doing and before it you could not pull anything but it gets pricey for a good trans
