My truck is starting hard after sitting over night with temps in the high 60's but even if it has been sitting for hours it fires right up when sitting in the sun and 90 degree weather. Something is obviously wrong. I replaced all of the glow plugs a few months ago and they all still test good. When I go to start it in the morning the plugs only cycle for about 4 to 5 seconds. After sitting out in the sun and 90 some degrees the light does not come on. First thing in the morning shouldn't they cycle for about 10 seconds? After I replaced them they only cycled normally (10 seconds) a couple times. Do I need to replace the controller.
