Have an 86 se v6 automatic, runs great, starts every time. Problem changed dash cluster because had no lights and fuel gauge pegged sideways, Rebuilt entire fuel system in the tank and all 6 injegters. turn the key but get no check engine light, door ajar or anything that comes with 1st click of ignition. I have lower interior lights and radio.Radio light goes out when turn the parking kights on. I thought i might have messed something in the fuel pump rebuid so I changed the whole gauge cluster but the secong does the same with the fuel gauge.Checked all my connections at the side of battery and power on both sides of 4 fusible links.Any help is appreciated. Thanks

I think the common point in all of those would be the ground.

Probalem solved, tear in the circuit board on rear of glustar and a blown 5 amp fuse, gas gauge still peged to the right. Any suggestion on the fuel gauge, or do i need to drop.
