Hi there! In need of a few ideas of where to look and what to do, i have a hyster 110xl, serial #g005d05554s. built in 94 i believe. The unit runs great but only for about 2 mins max then it stalls and becomes a no start problem. I have found that when it dies and doesnt start that its cuz no ignition spark. What would cause this machine to all of a sudden lose spark?
I guess i should mention that the distributor, ignition module, spark wires n plugs, battery, air filter, oil n oil filter, vaporizer and stop filter have all been changed. It also ran for a week after with no issues.
We had also ran a jumper wire from battery to coil and the unit didnt die, im at a lack of resources and dont know if i could run a wire from battery to ignition switch to coil and solve this problem without blowing up a new coil.
Any ideas/input would be greatly appreciated!
Thx
Daryk

Some of these G005 units did come with an engine control module. Tracing the harness from the distributor will lead you to it if it has one. Most likely located on the frame behind the right hand step hole. You will find the harness if it is there. Sounds a lot like a harness issue because it comes and goes.
Dont know what to say, ran a jumper wire to coil and it fired right away so its probably something in the ignition wiring. Somehow even after removing the jumper wire the machine is starting and running just fine for the past day. Its in use by the company again so until it stalls and doesnt start again i cannot diagnose any further. Ill get back to you on the serial #, thats what i have in records but i did not actually pull it off the machine itself. Ill still look into the oil press sensor/sender at a service interval or if it stalls again.
Thanks for the help everyone, ill keep ya updated!
i checked that serial number in hysters database and it doesn't exist. Are you sure you got that right? Of course there is the possibility this truck is older and didn't get included in some of the D005 truck ranges when they made thier system.
anywho... like edward said, double check the oil pressure sender, it is tied into the ignition circuit so this could very well be your culprit.
look at the oil sender, it may have more than 1 sender in a tee fitting. you may have a 'low oil pressure' shut off circuit, and you either don't have enough oil pressure at idle to keep the sender circuit 'closed', or the sender has gotten to a point that it needs more oil pressure than you have. also check the oil pressure with a gauge.
The sender with 1 wire will be for the dash light or gauge, the sender with 2 or 3 wires will be a "Murphy switch-sender".
I don't believe this lift would have a brain- it should have a standard electronic ignition.
Check for power at the coil & at the ignition switch when it stalls. If there's power at the ignition switch but not the coil (which is what I suspect you'll find) when it stalls, there's a problem with the wiring harness.
Heellllpppp!! This evil machine has returned to my shop, does anybody know what sensors would stop spark? How would i check fault codes on this machine? Still cant figure out why i have no spark... Cant find any opens, all volt/ohm test(s) seem to check out. Im lost
May have traced and solved the problem myself. Not too sure on what sensor it is, i believe coolant temp, coolant sender or knock sensor. Its located between two cylinders exhaust ports on the driver side of engine block. I cleaned the conector removing alot of built up green corrosion and the machine has start and run now for an hour.
Yea it dies at idle under no load. The parts were replaced because the machine would not start and, was not getting fuel and no spark after a summer of sitting without use. We had the machine up and running on new parts for a week solid. Also replaced was the ignition switch and starter. Ive been trying to follow the ignition wiring but with a lack of schematics it seems to get continuity through everything.
If the lift is sitting & just idling- does it still die? Sounds like a connection issue in the wiring harness.
Why were all those parts replaced in the first place?
