Just finished up the wiring to the rear of the car and wanted to check the fuel pump operation before I put in the truck aluminum. I'm running a carbureted 347 with a regular Holley pump. All my starter wiring is hooked up except the battery hot feed to the starter. Key switch is hooked up per manual. I ran a jumper from the battery to the solenoid side of the starter to check the pump operation. Went to check the key and found the fuel pump is off on accessory position, runs on off position, and runs on the on position. Is there something that needs to change with the fuel pump relay for a carbureted engine versus a fuel injected engine. I know the computer turns the ground on and off but I don't have that. Any body have any ideas?
