Changed cps, no change. Tach moves for sure now but still no white smoke, no fuel smell and definitely no starting. Where are these other 2 items you refer to and how do you check them...or do you just replace them?

Is there some type of fuel shut off sensor or something? When this happened the truck was producing white smoke but then the smoke just up and went away. Like the fuel was disconnected.

I've looked through the site and have found this issue comes up a lot but nobody ever seems to tell how they finally solved the issue. Unless of course there are a bunch of trucks sitting around in driveways falling of their frames.
