Having the same 118 trouble code with mine. Is 11 months old, under warranty, and has not run in 6 months. No service centers within 400 miles of me. I can "force" mine to start by doing the following; get a 6 quart sauce pan, fill it up full of water and bring to boil. Lift the bed on the unit and turn on the ignition switch. After the "prove-out" has completed on the instrument cluster look at the temperature gage. It should have 1 small bar at the bottom to indicate it is reading. Slowly pour the hot water over the coolant temp sensor on top of the water pump housing while watching the temp gauge. When you see a second bar light up on the gauge. Very quickly get in and crank it over. You will have to feather the throttle a bit to get it to fire. When it does fire up keep the rpm's a bit over 1500 for a few seconds. The temp gauge will drop back to 1 bar almost instantly after it starts. After it starts sounding a bit better (about 10-15 seconds) take it up to around 3000 rpm and hold it there until the temp gauge shows 2 bars (about 5 minutes). Then it will idle (it will be a bit erratic but will stay running) It will stay running as long as 2 bars are showing. Don't shut out off or let it cool down until you are done using it. I've been fighting with Coleman for 6 months trying to get mine fixed with no progress. Wish I would have never bought it.
