Im new to forums but figured this would be the place to ask, I have a 1985 F350 6.9 and first thing in the morning she fires over fine, but then stalls out. After trying to start again it takes a good amount of cranking time to turn over again. I just recently go the starter replaced and glow plugs so im not sure where to look now, Any advice would be really appreciated thanks in advance.

 

does the engine run ok after u start it the second time? or does it run rough?
