tcm forklifts mechanics , I have a 5000 lb. tcm lift , that is lp gas operrated. during operation i cut lift off. I tried to start it back but would not crank. lp gas was good, but i changed it just in case.It still would not start. I checked to make sure it was getting fire from distributor and it was.I made sure it was getting gas thru lp carb and it was. I checked pancake valves. all good. Forklift still would turn over but not crank. I removed plug frgom intake manifold and lift would try to run, almost like it was starving for air. i put plug back in and lift would not do anything. Where do i look now! could it be a fuse or something electrical. HELP
