I own a 2003 Jeep Grand Cherokee Laredo: 4x4 with a 4.0L. Recently the above listed codes popped up on my computer. Naturally thinking it is an injector problem, I replaced the injector in cylinder 5. Unfortunately, the problem was not fixed. To ensure there was a good signal going from the harness to the injector, I used a noid light. The light was consistent with no gaps or pauses; there was a constant pulse. Does any one know where I go next?

Check voltage drops of that injector and compare with others. Wires in the connector can be to bad to open injector properly but easily light up a noid light!

Do you have access to an oscillisope?

I do not have an oscilloscope. Is it a tool I can rent from a parts store? What readings should come across?
