from what im understanding the egi pump relay under the hood on a ka24e is the fuel pump relay, whats the other egi relay nxt to it? ive installed a new pump and hardwire and ran it to the battery since the battery has been relocated to the trunk. yet when i key the car the fuel pump relay isnt clicking or cutting on, but when we jump the relay in the trunk everything works properly. it looks to me that the relay isnt getting its 12v to send back to the relay to turn on the pump. any suggestions on what to check and verify that the relay is getting power and is grounded. ive tried looking at the wiring diagram in the fsm but have a hard to understanding it since electrical isnt one of my strong suits. im also using a new aem ecu so i dont know if the was something that the ecu controls the fuel pump with
