Have a 00 Ranger with a headache. It was a 3.0 auto, and now is a 4.0 5speed. Now when previous owner put motor in the 4wd and gas gauge quit. I have replaced transfer case, 4wd motor, dash switch, 4wd control module....... didn’t fix it. It is an 03 engine and computer. Before I pull the engine and painstakingly go over the harness I was curious if anyone has had similar issues.
