The Ford F150 engages starter motor, depending on a starter solenoid to close the starter circuit. When the timing solenoid and VCT solenoid fails, if you’re a trained mechanic, you can jump the connection manually with a screwdriver, or you can replace the solenoid and start the truck the normal way. You can replace the f150 solenoid yourself if you have mechanical aptitude, a few tools and about 20 minutes of free time.
Tip: Here is an installation instruction for f150 Model: 3L3Z-6M280-EA, and it can also be used as a reference for other replacement.
Open the hood on the F150 and disconnect the negative battery cable from the battery using the battery wrench. Push the cable end down along the side of the battery to avoid accidentally contacting the battery terminal during the replacement procedure.
Place the new solenoid next to the old solenoid on the fender well. Disconnect the wiring from the old solenoid’s right side, one wire at a time, using the socket set, and transfer the wiring to the same pole on the new solenoid. Repeat this on the left side until you have transferred all three wires to the new solenoid.
Remove the solenoid mounting bolts from the old solenoid with the socket set. Move the old solenoid aside and then move the new solenoid into place. Thread the two bolts in by hand and then tighten them with the socket set.
Reconnect the negative battery cable to the negative battery terminal with the battery wrench. Close the hood when done.
