ISM Acting Up

Hope I can get some help. I have no crank no start issue, total beached. Electrical mostly checked fine. Gear shifing hard to sometimes impossible. When actuating the ISM with Foxwell, everything checks out except for "Charging of Spring Accumulator" that says : The Actuation was not okay". When all modules are scanned, I get no fault code related to transmission at all. Is this the sign that ISM needs to be replaced, AND, is that the reason the engine does not crank & start. A complete beached whale.
When ignition in position 2, all dash lights, yellow and red, come on. But at start, no crank, no start. All fuses and relays in all 4 locations check fine.
Thanks
