I have a dead truck, died on the way to work, just like I had turned it off, and it won't fire back up. Not even a little. Thought it was the cps, so I changed it. Still won't fire up, but it sounds better. I realized that I didn't hear the glow plug relay click on, and no "wait to start" light, so I checked the fuses. The 30 amp on that curcuit was blown. I changed it and the new one blew. I checked the manual, and fuel line heater, glow plug controller and the powertrain control system relay coil are all on this amp. Any ideas as to which of these is giving me trouble? It's a manual transmission, don't know if that makes a difference.
