Ok so this past week my 2000 4.0 died on me just in front of my house. Got it pulled up in the driveway and changed out the crankshaft position sensor. Still nothing. Got to testing voltages and come to find out my fuel pump relay(RL12) and RL10 are not being activated. I am getting 12 volts from the hot side but when I go to test the other side of the relay coil i get 5 volts coming from the BECM. Any ideas as to why they would not be coming on? Any help would be appreciated.
