P0670 Code?
I am thowing the P0670 code. It says thats a short surcuit in the glow plug control module. Is this a serious thing? Does it need to be fixed right away or can I get by a couple weeks without it. How can I fix this? If it is something I can do I will do it. Where is the relay for it and how would I check that?

P0670 is Glow Plug Control Module Control Line Failure. Look for an open or grounded circuit or shorted GPCM. It could also be the GPCM ($200 at NAPA).
P0671 through P0678 are failures in the glow plugs for cylinders 1 through 8, respectively.
P0683 is a failure in the diagnostic circuit for the GPCM. Historically, this has meant a bad GPCM.
I'd suggest you have either a bad electrical plug or wire to the GPCM. Remove and inspect the plugs to the GPCM for security, damage, wires. Suggest updating to "2000-2003 Electronic Glow Plug Control Module Harness Repair Kit", TSB 04-22-8, Ford part number 4C3Z-12B568-AA.

The GPCM is the finned unit in the background (the GP relay-looking thing in the foreground is for the IAH). The extra wiring you see going to the GPCM is the TSB repair kit above:
