Hard start Montero


Neighbor has a 1994 Montego 3.0 V6 and has ask me to diagnose why it is so hard to start the first time after sitting like overnight. Checked temp sensor and it's ohms are in range but when I checked for voltage at the connector there was none checked farther up the wires and it is dead. Question! where does the temp sensor get it's power? finding a readable wiring diagram is next to impossible. Tanks Dave
