    Truly appreciate any help on this. 2015 1700 Commander will not start in hot weather. Happens only on bright sunny days after and has been sitting in direct sunlight for about 20 minutes or longer. Mechanic checked fuel system and gas cap. No expansion issues and no warning lights. Fuel pump checks out perfect as well as new plugs and constant engine service. Bought used at 13,000 miles and has been doing this every summer to date (20,000 miles).. Engine turns over but no fuel is being injected into engine until I turn throttle about 1/2". Slowly the fuel pressure builds up and runs fine after about 3 minutes of revving engine. Seems like the Electronic Module is not pushing fuel to engine under the 'hot' conditions.
