Are fuel injectors ( bosch top feed specifically ) polarity sensitive? and if connected wrong, what would the difference in operation be?
I ask, becasue I fitted injectors to my other car, as a DIY install, and have only just discovered a + symbol on one side of the injector. It has been running fine though for 1300 miles, and its a bollox to rewire the loom. Is it worth changing? I cant get the pins easily out of the plugs either to swap them round at the injector.
