I am working on a Hyster H60XM with the GM 3.0 engine. I cannot get the unit to run and it does not have spark. The ECM is checked and is good. The throttle body and all associate sensors are check and are good. The crank sensor is checked and good. The distrbutor is checked and is good. The ignition coil is checked and is good. Where do I go from here? Thanks in advance for your help.
