No start after dummy plug replacement

Please help!

My truck (220k miles, no known mods other than straight exhaust) started having hot start problems a couple weeks ago. Thanks to this forum, I narrowed the possible culprits down and started with the fuel rail plugs an stand pipes. The passenger side dummy plug o-ring was severed and the driver side was at about 50%. After replacing the driver side, I reassembled and attempted to start the truck. I wanted to make sure everything was ok before tearing into the other side. No go. It turned over but did not 'fire'. I disassembled and checked all connections including FICM. They were loose, so reinstalled them and placed wedges under to ensure their proper connection. Still no go. Went ahead and tackled the passenger side. No major problems with that side. Truck still won't start, but now it fires (I know this is not a proper term, but you know what I mean!) every once in a while after about 2-3 attempts at 10+ seconds per crank. while cranking it blows white smoke out the tailpipe.

Any thoughts?!? Thank you!!

Aaron

As in the gremlin will blow out the tailpipe and everything should be fine after an initial start?

If it's smoking out the pipe that's a good sign. Keep cranking. It will fire up.

Don't do that. 20-30 second intervals with a minute or more to cool down or you will burn up the starter.

So it finally cranked up! But now it's running rough and has no power. Took to parts store to have codes pulled. They pulled 15 codes, ranging from all 8 injectors to glow plugs, cam position sensor, crank position sensor, turbo underboost... Any ideas?!

Yeah your FICM harness isn't plugged all the way in.

That was it exactly! crawled in with it running and played with the connections. Smoothed right out. Made tighter shims and now we're in good shape. thanks for all the help!! First venture into diesel repair after years of working on gas engines, will do it again thanks to great and timely feedback!
