I appreciate all the suggestions. For some strange reason, the van is starting now. It's done this before where it will start fine for a while (sometimes for 2-3 weeks) and then start acting up again. But when it does, this time I'll be ready.
I'll take a harder look at the inertia switch, maybe even cut the wires and by pass it completely. I'll comeback and post update here.
Thanks again for all your help.
