The power lift works just fine and all the other electrics are working perfectly.
For all the reasons given re connectivity etc,the condition of the batt can be critical, as it may have enough power to turn over the engine, it may not have the additional wack to send a spark to the plugs at the same time.
Thats why car's start better with a shove - the battery only has supply the spark,you are supplying the power to turn over the engine.
Start from the battery end and be fastidious with the cables,borrow/change the batt to eliminate it as the route cause.
I would then go to the plug lead/plug against the head to check I was getting a spark on turnover.
