even different working coil does not work on cylinder 1. Can the computer cause this? Is it in the wiring? When using a tester all cylinders/coils wires light flashes green except cylinder 1, light remains on even when vehicle is turned off/on. Help?

    Remove the coil and insert a good spark plug into it, while engine s running touch the metal part of the plug to a metal ground or ground it with a wire, see spark? That spark plug wet when removed? Got compression? Got injector pulse? Got code PO301? Don't care?????
