High Elevation Adjustment
I've noticed that my 99 F250 PSD is extremely hard to start at our new home at 8500' elevation. The only way for a sure start is to plug it in overnight. At the lower elevations (3000'), it's not a problem and starts every time. Is there an adjustment for high altitudes for air-fuel mixture?

i've just experienced the same problem. I thought it might be temperature. I've been told there is a soleniod behind the feul filter that ford has had a problem with in the past. Two of my friends have had to replace theirs. Please let me know if you find out anything

I don't think it is temperature related. At the same temperature, but lower elevation, I don't have the problem. At the higher elevation, white and gray smoke are exhausted every time I try to start. It seems like the fuel/air mixture is too rich. Maybe someone will help us solve the problem.

I do not think there is an adjustment, at least not for mine - it starts the same at sealevel, as it does up a mountain. If it is cold, it makes smoke, sometimes volumes of it, but warm it starts as well at 12,000ft + (Engineers pass, CO favorite truck camp place) as is does at 0ft.
