What could be the problem with a 1989 GMC Suburban getting no fuel delivery despite a new filter relay checked all wires no voltage at rear pump plug wire?

possible ignition module (that's in the distributor ) or broken wire, bad ground

just a thought

I don't know about a Chevy but on the ford if the engine control computer relay is bad then you wont get power to the fuel pump relay.
