Ya man, I'd hate to see you have to take the head off. I have not dealt with this personally but i bet it is extremely crappy. If you want some help just let me know, I can offer another set of hands. By the way, welcome to FTE!

Be careful if you choose the start/shoot option. You will most likely have a hole in your shop. This could be very dangerous but effective. You may want to remove the hood and valve cover and do it in a big field that way nobody gets shot. LOL
Good luck and keep PB blasting it, twisting and soaking.
You know I made a slide tool with a set of vise grips recently. I removed the bolt from the back of the vise grips and replaced it witha long piece of all thread. Then slide something heavy on there and put a big washer and nut on the other end.
Now you can clamp the vise grips on the GP and slam it out of there.
Almost forgot, WELCOME to FTE.

Wiring a switch to bypass the solonoid
I have had to replace the glow plug solenoid twice now in the last 8 months in my 96 F-250, 7.3l turbo diesel power stroke. My glow plugs are brand new since I thought they were bad. It still wasn't starting. When I tested it with the screwdriver it fired right up. I am tired of buying the box so I wanted to wire it to a switch in my dash but am not sure how to do it. (The current solenoid box that is in it is bad and I don't want to replace it with a new one). Any suggestions?

zombie, an easy test is to jump the 2 large lugs on your GPR. that'll send power to the GP's. if she cranks up after having the lugs jumped for about 10 seconds, then thats your problem. my 99, i dont have to wait for the GP's to warm up in 80 degree weather, but the ol 95 might need it. it might also be that in the couple seconds of cranking on the 99 it still gets the plugs hot enough to fire. good luck to ya, also starting a new thread might get more attention then adding to a new one.

7.3 Glow Plug Smoking Issue
OK, I've been out of the mechanic game for a while and I need to help a freind out. When he turns his key on the GPR kicks in and heats up the plugs and the engine will run, however, the relay wont kick off and the metal tab that goes to the modual will start to smoke! Any thoughts? I'm assuming the modual is bad. Does anyone have a wire diagram of the relay. I want to make sure it's wired correctly as some "person" already replaced it once.

Still no good. Forums abbreviate the text associated with a link. Copying/pasting the text has the effect above ^^^^.
Try these:
97-15A 7.3L DI Turbo

But the mention of "metal tab" and "modual" (I presume you mean "module") implies that maybe it's a California truck. That diagram doesn't appear to include the CA truck diagram. In any event, the GPR should shut off after no more than two minutes. Does it eventually shut off when you turn the key off?

Yes it does shut off when the key is turned off. Seems like a timer issue, just wanted to make sure before I replace it
