03 Dodge Ram 5.7 won’t crank just one thunk

[Safetygirl]

I need help I have read other post but haven’t found no answers. My 03 dodge ram 5.7 1500 when I go to start it will give me one thunk noise and nothing else. I have changed the starter, new plugs and wires, new ignition switch and still nothing. The truck is getting power and I checked to make sure engine wasn’t seized so I’m at a loss because I have no DTC’s coming up.. and I’m tired of buying the what if parts as they start to drain the bank. So any help would greatly appreciated. I will try to get sound posted this evening as to the thunk noise it makes when I turn the key over

try turning the engine over by hand.

Have you had your battery LOAD TESTED ?

Clean the terminals and all of the ground connections you can find , then try.

I used a torque wrench and the motor turned. I’m trying to figure out how to download video of the sound

Great. That means you have an electrical issue, if the starter is good.
