I am having proplems on cold starts,i no its summer but on some cool mornings when its about 50 my wait to start light is on for for about 2 seconds it off before all the other lights go off. When i start the truck it sounds like i dient wait for the light and it spudders like when you dont let the heater do its job. What controls the grid on how long its should stay on for??? im thinkin a bad sensor maybe?? The truck had no proplem over the winter.. any ideas??? thanks

Your truck should start easily without the grids. Is the fuel system tight? I would be checking for air leaks.

ill double check for leaks, but i just started the truck for the first time since yesterday and its 75 and it started perfect:confused013:

does it start right up after the engine is warm?

ok update this morning it was 62 and the wait to start light was lite for 6 seconds, and it started up fine.the trucks starts fine all day long its just the cool morning start it acts up

Have the sensor temperatures read by dealer's scan tool to assure they are in calibration. You may have found a hole in programing for grid cycling. Are both grids working properlly??
