Check fuse no.10 20amp in the power distribution box. If okay do below

At the inertia switch jump the dark green and yellow to the pink and black-did the pump come on?-Get back.

I have power going in and out of inertia switch, check with test light. I have no power @ pump, any other suggestions. Does power go from inetria switch direct to fuel pump?

Yes it does. Try directing power to the fuel pump from the battery if it doesn't come on-the pump is defective.
