Glow plug "tip" didn't come out with the body

Pay extra attention to your control box.
It might be frying the glowplugs.

was my mistake trying to yank them out, I ended up getting the plug removing tool and it made the job a breeze.

All 8 of mine were smoked. Lucky they came out intact but it was a chore.
Just for kicks I left the power leads off to all the glow plugs and turned the switch
to run positions. Wait light came on as usual with the big relay in the smart start box turning on with a clunk. Wait light goes out but still constant power to GP wires until I shut switch off and relay shuts off.

Starting to investigate issues with the smart start box and or possible TSU temp sending unit.

I thought the temperature sending unit sends a signal back when it is hot enough and shuts off the plugs. I’m new to this so I might be wrong.

I think I may have fried mine. I accidentally hooked up the battery while the ignition switch was in the run position. I realized immediately as it arced due to the glow plugs drawing current. Ever since, the wait light blinks for about 4 seconds and then goes off. The glow plugs are turning on during start, and pulsing during warm-up was expected, just getting the blinking light.
