The wait to start light on my 06 only comes on first time starting for the day and only after it has been off for 3 or 4 hrs. Is this normal? My 04 light came on every time I turned the key on

 

normal...onyl comes on if manifold temp is below 55 degrees

 

yea i sure am loving it compared to my old 02 F250

 

The 06's no longer do the "bulb check" that pre-06's did everytime the key is cycled. If you key on and do not see the wait to start lamp, go right to cranking. If you see the lamp, you are getting pre-heat and you should wait to start.
