Engine Starting Problem

[BFisher]

Here is an odd one for somebody. I have a 02 f250 with 7.3 powerstroke. 190K miles. A month ago or so it start to smoke and idle rough at engine start (especially cold). Diagnosed what i could but finally had to take it to the dealer. With his equipment, we found out that at engine start the engine will run fine for about 3 seconds and then the whole drivers side bank of cylinders stops firing. After about 30 secs the number 2 cylinder starts to fire, then the number 4, then the number 6 and finally number 8 will start to fire. This whole process takes a few minutes before all cylinders are firing. I am sure the time is dependent on temperature. Any thoughts on potential problem. Thank you.

I did, it turned out to be a brass injector sleeve that was cracked. It was allowing coolant to back up through the crack in the sleeve into the fuel rail on the drivers side. when you tried to start it the front cylinder on that side would fire first then each cylinder going aft from there would start to fire when the coolant and been expelled and replaced with fuel. Smoked like crazy until all that coolant was expelled. Good thing for me it was summer and hot, it probably never would have started on one bank of cylinders in the cold.
