I've checked all my fuses and they were good and checked the connection to to my A/C fusible link and still had connection. I'm not sure the cause is because of my fans running to the ignition during startup might have shorted something out. I do know my fuel pump is working properly but I read somewhere that it is better to use a relay switch from inside the vehicle rather than in conjuction with the fuel pump. I know this thread might be confusing but I need input to prevent my car from overheating. As I previously stated I did not due the install but let a local shop install them.
