I replaced the cam and crank sensors with Hitachi CPS0003(23731-6n206) and CPS0008(23731-6j906) ones and there is no change.

I wanted to ask if I have a separate LP gas controller (22710-fu460) or if mine is built into the ECM? I looked and looked on the lift for a separate controller that I found while fumbling through the sxkomatsu web parts list, that thing is confusing...
My lift is FG18SHT-20 sn 675820
which page should I be looking at in the parts manual?
this is the one I am using now
