I just purchased a 580 EFI which has been working fine now it is hard to start and has a bog on the low end. The fuel pressure has been checked and the wires coming off the mag there is good fuel pressure and lots of Ohms. Have now narrowed it down to maybe only power going to one injector. Is this a broken wire or is there a sensor or something that regulates each injector? The injectors have been taken out and cleaned etc . I assume each injector fires at a diffrent time so running both off the same power is not possible. Is there anyway to run new wires for power and where should they come from?
