Have you checked the inertia switch? Maybe it got tripped? Black rubber covered swith on passenger side firewall. Push down on top. Or bypass it.

There is also a fuel pump relay under the hood near charcoal canister, make sure it's connected.

I removed the battery negative connection, bridged the input to the inertia switch, removed the fuel pump from the tank (it is no big deal really) filled it with alcohol and did a direct connection from a battery. There was a one second hesitation like something was stuck and then it squirted a stream of alcohol two feet long.

Upon replacing it the vehicle started immediately and ran smoother than ever - for a week - when the week-old ignition amplifier unit gave up the ghost.

Come to think of it: you get power to the fuel pump relay - does the relay in fact close and make a secure connection?
