Just put the new motor in after the timing problem before..Starts up and sounds pretty good but could sound better.It has a rough idle so we check the vaccum lines they are all good. We check the fuel delivery and the passenger side fuel supply isnt working. We pull one driver side injector harness off and you can feel the drop in power so we check the passenger side and has no effect at all. We pull all 4 off and nothing sounds the same from initial start up. We cleaned the injectors and still the same. What would cause this problem? All wires and harnesses are on correctly. Could this also be a spark problem on the passenger side? Any help would be great guys, thanks.
