I have a 96 Cobra with a Vortech SQ supercharger. After changing an idler pulley this week I went to start it up and the inline T Rex pump didn't work. I checked the relay (in the trunk) and it tested fine. I connected the power supply from the under dash fuse box directly to the fuel pump supply bypassing the relay and the pump started working. I then checked the yellow wire that connects the relay low side power to the cars cars fuel system and I dont see any voltage when the key is turned on. I tested the inertia switch and it has continuity. I'm no electrical diagnostic person does anyone have advice on what the most likely culprit is from here? Thanks!
