Ok first off your thermostat is failed in the open position,go to Ford and pick up a new one they cost $28.00. Get the Ford one no chinese pats here, the factory thermostat fails in the open position, you need to be 195* ish for engine to run properly and your milage will surely go up after you install it.
For the glow plugs do you have a inductive amp meter, you want to clamp it on the wiring harness right off of glow controller and watch the amperage levels per side. The glow plugs draw 10-12 amps each compare both sides. Make sure the fuse is good for glow controller. Cant see all of them fail at once.
