Between the battery and the firewall there is a factory wire splice where 5 ignition hot wires are all spliced together. These wires are very small and in the past there have been problems with one or more wires breaking off at that splice. The wires at the splice is either pink, blue, or red, depending on what year the truck is (I forget which year had which color wires). See if you have voltage at the throttle position sensor, the cam sensor, and the dist sensor, or the fuel pump relay in the under hood fuse box, if any of them does not have power with the key on, you need to open up the wiring harness and look for the splice with the broken wires. I've encountered this from 91 through 94 Dakotas.Gene
