Message: [QUOTE="Trqmnstr, post: 830547, member: 12776"] Had a 02 7.3 that would take forever to start, 30-45 mins of glow plug cycling 1.5 minutes at a time and cranking every third cycle when below freezing, would smoke and miss like crazy for about 30 seconds after it finally fired. Plug in block heater for 1/2 hour and it would start right up with no smoke and idle smooth. I think it was a glow plug issue. 06 needed 2 glow plug cycles, would throw a puff of smoke and idle rough for a few seconds sometimes when cold before i switched to rotella t6 and put some hot shot secret in. Dont know if the additive helped tho, may have been just the oil. This i think was a stiction issue. Ive also noticed that about 10 seconds after the buzz cycle stops it looses all fuel pressure on the gauge. If you dont key it within a few seconds of the gauge dropping to zero it wont fire right away. Idk wtf this is about yet. Have you tried plugging the heater in? If solves it i bet you have a glow plug or 2 gone. [/QUOTE]
