No Start Condition

[BSoldie]

I need help please! Earlier this evening I was plowing snow with my 97 2500. I noticed the "ABS", "AIRBAG," and "BRAKE," idiot lights all glowing on the instrument panel. I thought that I might have tripped a sensor somehow plowing over the rough pavement. There appeared not to be any problems with the truck at this time. Then I noticed that the blower for the fan wasn't working either, yet the defroster was in the "on" position, and I could here the clutch on the A/C compressor engaging and disengaging but no air was coming out of the vents. I shut the truck off to see if it would reset itself, then it would not restart. I just replaced the fuel shutoff solenoid. My battery connections are both tight and clean, howver, my left side positive terminal battery cable was a little loose. I tightened it and tried jump starting the truck with another truck that was on site just in case I was getting enough juice out of my batteries. The truck still won't even crank. A single faint click is heard once only when the ignition key is turned to start. The two solenoids on the driver side fender appear in good condition as well. All fuses checked out okay, as did the relays in the relay/fuse box in the engine compartment. I was wondering if anyone could help me as the truck is now stranded on site.
