Todays’ video We loaded up the parts cannon to figure out what was wrong with trevors Jeep. He was driving home and the Jeep just died. All it does is crank and no start. I verified fuel pressure which was good. There was no spark and power at the fuel injectors. The computer tested good and the Crank Position sensor tested fine as well. At this point we swapped the computer to see if the fuel control drivers in the computer were shot and that wasn’t the case. Everything came down to a simple fuse being blown that was overlooked because apparently they were checked. However replacing the fuse doesn’t fix the problem causing the fuse to blow. In the end it was the o2 sensor wire that had worn though and would cause a short.
