Get an new computer, had the same thing happened to my 2000 RAM van, a of a sudden...no power,gauges go dead and no startup. I wiggled the rightmost harness on the CPU and the power distribution center clicked,the gauges came on and it would start right up. This eventually led to a new CPU because of corroded points inside the computer housing. Hope it helps(FYI,new CPU e-bay is 140 bucks if you put it in yourself. Hope it helps
In a quiet inviorment.. Turn key on.. Start wiggling, twisting wiring harness to PCM and the fuse/relay box while listening for clicking of relays and various engine electrical components coming to life... Wiring harness chafing and poor electrical connections are common... Possible rodent damaged wires! .. Hint .. ASD (Auto Shut Down) relay should click each time key is cycled .. OR .. the 'electrical connection' is restored!
