I'm getting close to stumped here... my engine was a strong runner a couple months ago. I hadn't run it for a while as I was working on getting my 4L80E ready for use. Forward to a few days ago, it won't start. My glow plugs cycle for 8 seconds (S3) and warmth can be felt on the block at the plug, I crank and the engine spins and I hear compressions as it spins around, and I see cold, white smoke in the exhaust.
I removed the air filter and found no restrictions, so reinstalled. My fuel was getting old, so I dumped it all out and put in 5 fresh gallons of diesel. Before attempting a start, I cleaned the filter housing, changed both filter elements, and bled the system. I also put on 4 fresh batteries (two parallel sets in series) for some serious cranking power. No start.
Here's the kicker that's confusing: I pulled wire 54a to compare smoke and I saw no difference after a full 20 second cranking cycle. I tested to ensure there was power present at both wires with the switch in run position and the engine cold. I'm going to try bleeding fuel at the injectors just to be sure there's not still air, but failing that, does anyone have ideas?
