Similar unit to a Hyster Forits 80, digital 2 line dash, EFI, LPG V6
This machine had a problem with the hydraulic valve body and was repaired. I did the final assembly of the machine and took it for a test lift. Machine started up fine, drove ok etc. When I went to pick up a bail of pulp, the machine stalled. And then it would not start. There were no strange noises etc.
The computer is not showing any error codes.
This is a real head scratcher, we've done all the "logical" things with it. Have fuel, spark air etc.
Attempting to start it with "fire start" yields no results.
We are now at the stage where the plugs are pulled and doing a compression test. Everything specs out.
We cooked a starter from (assuming) attempting so many cranks on it during debugging. A new starter was installed and a strange observation was made. When the old starter was failing, you could tell it was loosing power/strength. The new starter is showing the same signs even with the spark plugs removed. One would assume that it should toss that engine over with little effort. (There is oil on the stick).
We're stumped, no idea what to do next.
Comments appreciated!
Thanks!

Hi, funnily enough, about an hour after writing this, it dawned on me that maybe we've introduced a load that shouldn't be there. This seems logical as the first starter got so hot that it was smoking. It was not benched as it appeared the starter was worked to death. The replacement one is doing the same thing (getting very hot, but this time we are aware of it and not "abusing" it).
Yes, checked historical codes as well, there are a couple in there but they were there from time of purchase of the machine a couple months ago.
I've got a feeling you're right. Today (time permitting) we'll attempt to unload the pump or pull it and see if the cranking improves.
Thanks!!
since you just changed they hyd. valve, have you considered seeing if you have pressure on some line where you should not? releasing pressure all the way around?
also, did you bench test the old starter to confirm the starter was, in fact, bad?
also when you say "the computer is not showing any error codes? are you able to access the historical codes function (service password or laptop software {proprietary} required)?
