Vehicle runs great when running. What happens is sometimes when trying to start up no red lights appear on dash hence no power to fuel pump. Interior lights, radio, headlights all have power. I have to play with the ignition key turning it on/off and the dash lights come on eventually then vehicle starts up and runs with no problems. I was told it could be the ignition switch inside the steering column. Not sure where to check next.

My info shows an oil pressure switch in the fuel pump circuit, even without the relay, once you crank it enough to bring up oil pressure, the pump should run. That's not ignition feed, the ecmB fuse shows to be hot all the time.

The problem may very well be the switch, overall. The dash lites and a bunch of other things are ignition feed.
