-I can hear in-tank rear fuel pump working properly.
-Checked all fuses on inside driver's kick panel, all good.

After the inertia switch the wire splits and one runs to the LP pump and one runs to the HP pump. Since you have power at the LP pump you must have a break in the wire between were it splits and the HP pump.

First, I want to thank everyone that tried to help me out. I found the problem. Ken, I tried to bypass the Inertia Switch but it was no good. I figured it was a problem in the Fuel Pump Relay or a fuse/fusable link. After 2 hrs with a multi-meter, I dicovered that it was related to a fuse, but not where I thought. There is a ground wire with a fuse in it and as it turned out it had come loose from the neg battery terminal. It was a free fix!!! Woooo Hoooooo!!! Thanks again guys...
