I have a 1997 Dodge Ram 1500 v6 3.9lt magnum 2 wheel drive. This truck has been sitting for a year and I have been working on and off it for a year. It ran fine till I turned it off and went back the next day to start it. You turn the key and it makes one knocking sound and that's it. I have bought a new battery a rebuilt starter and neither of this fixed the problem what could I be missing. Any help is greatly appreciated n

 

Can you tell where the sound is coming from? Is the starter solenoid actually engaging, and the starter just not turning the motor? Or is all you are hearing just the click of the starter relay?

Can test the relay, just swap it with the horn relay. (both in the PDC, under the hood, right behind the battery.)

 

We pulled the starter hooked to the battery and it didn't turn. The sound is not a click click click it is just a quick loud click or knock at that's it. Also removed belt tried to turn motor and it didn't move

 

Sound like the bendix is engaging but not turning the motor. Take the plugs out and try turning the motor with a socket/breaker bar on the damper bolt not by hand.

 

Tried turning the motor with socket and breaker bar. Put the socket on the pulley that is in the closest to the ground. The socket was 1-1/2 inch. It did not turn or move pulled it from right to left looking at the front of pickup. Plugs were removed and belt removed.

 

Take off the serpentine belt, and try again. If it still won't turn, time for a new motor.

 

I have already taken off the belt still will not turn. Please tell me there is something else besides a new motor

 

That last sentence there got butchered by someones auto complete.

If the crank won't turn with the starter out, and the belt off, time to pull the inspection plate, and unbolt the torque converter, and try again. Unfortunately, to get all the bolts out of the torque converter, you need to be able to turn the engine.........

 

Oh yes always love the auto correct or auto complete. Is there another way to check to see if it is the engine and if it is seized can it be undone. If it needs a motor what year dodge motor would fit in it.

 

Drop the pan and take a look. If you catastrophic damage or a seized bearing it won't hart to find.
