Hyster H90XMS:
starter kickback-misfire

H90XMS LOO5V replaced heads, cap, rotor, plugs, wires, alternator, crank sensor, cam sensor, coil and igniter. no mil lamp codes. Can't access computer for data stream for lack of software. tier II (2005) spectrum. Experience has shown that delay timers don't usually help. Engine timing is correct as is firing order. Added grounds for electrical components including computer. Have two machines with this problem. Did cap test for GM 4.3, and cap is ok. Engine is too close to body of truck to pull and install plug wires one at a time while engine running. any ideas ? I can't be the only one with this problem. Thanks in advance

Sounds advanced! Starts better with #4 plug wire off.
From my understanding 3 shift driver said it started missing very bad and then it just wouldn't start!
Ok so he broke a starter bolt from back lash

soooo...
on GM motors, I often suggest adding an oil pressure switch to the ignition circuit if the time delay does not do the trick,,, but as this is a tier 2 truck, and the computer does the same thing by reading the crankshaft sensor, I think there may be a different problem that is not really ignition related, but mechanical to the starter-ring gear. I would suggest that the ring gear is _carefully_ eyeballed, and _complete_ tuneups done, regularly. also checking to be sure the key switch requires complete turn off before returning to 'crank' from run.
