Hoping someone can help me understand the wiring diagram in the FSM? I keep blowing F22 fuse, which from what I can tell fuses A61 which has the fuel pump relay, but also via C107, pin 14, it could be blown by either O2 sensor.
My main question is whether this can also be blown somewhere else? On the other side of the fuel pump relay, of course we have the Fuel Pump itself, which seems to be a candidate, but the dashed line from C100 over to what appears to be the combo flasher. What is this dashed line? Can it blow F22?
Any other ideas? Another note, the fuse blows if I just start the jeep and let it sit there. Sometimes 5 minutes, sometimes 30 minutes. The O2 sensors are brand new and I checked all their wires under the truck, nothing seems to be rubbing.
I am on page 8W-10-31 of the 1999 FSM
