Hey BR3W CITY. Thanks for your reply. Better explanation: My buddy wired a manual on/off switch to activate his fuel pump. Before he cranks his truck/swap with the ignition key, he manually turns on this switch. It's crazy. I saw him do it. This switch adds fuel or turns on the fuel pump which, adds gas to the fuel rails. He feels his swap starts better this way. He states that this procedure helps his truck starts quicker. He sometimes experiences false starts or the vehicle just cranks until the motor catches and run. i asked him, what's wrong with the PCM controlling this function. I feel that there is something needed in the tune. He has a mail order tune from II,.@$$)(;:/-. Any help is greatly appreciated. BR3W.
