[burtonboarder]

i don't know jack about electrical so here goes. got my swap done, ran great. got on the dyno yesterday and got all strapped down. fired it up and got up to speed. then "no bus" flashed on the odometer, lift pump quit runnin, and gauges went dead. i checked the engine control fuses and they were good. where do i go next? :thankyou2:

check the ecu ground in the wirring harness by the ecu and the two grounds on the passenger side that have plug in to the neg bat cable

happened to me once and it was the fuse labeled "engine" inside the truck not under the hood.
