No start issue

Bought the truck a month ago. 97 psd with a five spd. It was running rough and smoking a bit but I drove the piss out of it for the last month. It has started great and ran pretty good the whole time. A few whitish colored smokey starts now and then.
Took truck up to the woods to work last weekend and it pulled the hills pretty good. Got up the and it fired up three or four times to keep the heater going.
Got in to head home and no start.
Getting fuel vapor from pipe. It fired just a little bit a few times. Wts light comes on. Tach moves oil pressure comes up.
So today I went back up with new ipc sensor, cps, fresh oil, topped off hpop it didn't go down at all after cranking. New glow plug relay, checked all fuses and put new PCM relay, new batteries. Still no start. Just fuel vapor and a few blurps of firing.
Was looking at gp system and I don't get any volts to hot side of relay????? Did have 12v on little red ing. Wire. Is there a fuse in the system? I could open the fb cuz I got the wrong damn wrench from parts house. Also I plugged the truck into a generator for am hr and a half and don't the the block heater is working. It didn't make any change on the Ginny when I plugged it in. I am going back up tomorow hopely with more stuff I can do or tow it home.
Also my scanner brought up 126 codes but couldn't link up to read them. What would that mean??

The "wire" from the junction point on the starter relay to the hot large terminal on the GP relay is actually a fusible link. That could be fried. You could try putting a jumper cable between one of the battery positives and that terminal on the GP relay, then turn the key and see if the relay clicks. You'll know the relay is actually energizing the plugs because the volt gauge on the dash will be LOWER than before. If that doesn't work, just to get it to start, put the jumper cable on the _other_ big terminal on the GPR, for maybe 10-15 seconds, then try to start it. That directly energizes the GPs. Then you'll at least know it's a problem with the relay circuit(s).

Block heater - check the resistance of the two blade prongs on the plug; should be about 14 ohms. Also check resistance at the block heater itself. If you get 14 ohms at the block heater, but higher at the plug, or "infinite" (open) at the plug, then the cord is fried. Replacement is available via NAPA, about $22. Often it's the end right at the plug where it's fried, so you could wire in a new plug.
