How does a starter work on a truck?
What’s called the “starter” has 2 power connections – a large wire that provides power to the starter motor, and a smaller wire that powers the starter solenoid. When the key is turned to start the solenoid will engage the gear on the starter with the ring gear on the flywheel as well as trigger the starter motor to begin turning.
What happens when there is no power to the starter motor?
If there’s no power to the starter motor but power everywhere else you’d hear a “click!” noise when you turned to start but nothing else – ie. no whirring or cranking noises.
Why does my starter not turn when I turn the key?
With the key in the start position you should see about 12V on the small wire. If you have the 12v at that wire the solenoid is the most likely fault. If you don’t have 12v at the small wire, you need to get a wiring diagram for the truck. You then have to follow the circuit back to find out where you do have 12v and where it stops.
Why does my starter spin when I bypass the solenoid?
If the starter spins when you bypass the solenoid the starter is working. By jumping out the solenoid terminals both of which are “hot” by the way, you have tested the starter motor. You should be able to see at least one smaller gauge wire and the battery cable attached to the starter.

What should I do if my starter is not working?
The starter pinion gear engages this wheel to make your car engine crank. Remove the starter motor and set your transmission gear to neutral. Rotate the crankshaft manually using a ratchet. There is a pulley at the front or bottom of your engine block. The pulley should move as you watch how the pion gears are reacting.

Why is my starter not engaging the flywheel?
Tighten the mounting bolts and other connecting wires. If the mounting bolt is loose, the starter drive will not engage the flywheel properly. It will make a grinding noise when you try to fire up your engine. What this means is that the pinion gear on the starter is clashing with the ring gear on the flywheel. Check the pinion gear.
Why does my service say manual ( trigger start )?
If your service says “Manual (Triggered)” it means that there is one or more triggers enabled. To look deeper into this, first find the service name: Open up services (By opening the “Run” dialog and typing “Services.msc”. Locate the service in the list, right-click on it and click “Properties”.
What’s the difference between triggerinfo and trigger start?
TRIGGERINFO is the command to actually modify the triggers. To show all SC commands and what else you can do with this, just type SC and press enter. Again, please use great care when modifying services, and if you aren’t sure of the outcome, keep reading about it until you do.
Where is the starter motor on a Nissan?
If everything before this point looks okay you need to test the solenoid trigger wire for power to determine the condition of the starter. The starter motor is usually underneath and on the right or left side at the rear of the engine block (can be under the intake manifold like on some Nissan, GM and Infiniti V8 engines.
Can a bad ignition switch cause a truck to not start?
But you could have two separate problems which in case the posts above are highly possible. That ignition switch has little copper contacts in it that can break and throw you for a loop. Sometimes when one goes bad you can see heat damage on the backside of the switch.
Is there a no crank no start truck?
Discussion in ‘ Freightliner Forum ‘ started by sixxjoe, May 19, 2013 . I have an 07 m2 with a no crank no start…I have power everywhere is should be…starter alt power block on the fender well but when I key up the truck I get a beep and no gauge sweep or codes.
