Please please please don't use ether on these trucks as the glow plugs will fire it off and make for a MUCH worse day.

A failing CPS will indeed cause a loss of fuel economy as the commanded timing of the injection pulses is skewed from where they should be. Timing is pretty critical on a direct injected engine.

ether = dead engine 80% of the time

No, I'd never use ether on a diesel. I rarely even use it on a gas engine.

MPG went into the crapper about 3-4 months ago. Sort-of around the time the weather got cold. Might have been a combo of winter diesel and the failed t-stat.

For the CPS, I figured it either worked or didn't. Anyay, even after I replaced it the fuel economy stayed about the same. We'll see how it looks now with the new t-stat. Or if it improves in the spring.

Ya, but then you don't have to change the oil for 15,000 miles...
