I have a 2004 Dodge Ram 3500 5.9 Dually. When I go to start the truck, I turn the key to the on position, all lights and gauges come on with no problem. When I go to start the truck I get nothing ( motor won't turn over, no dimming in any lights, nothing). I've gone through and checked all fuses, everything's perfect. I've replaced the ignition switch, still nothing. Both batteries have been checked and both are at 100%.

I have no other ideas, can anyone help ?

 

bad starter or solenoid. if your starter is turning over but not the motor, your teeth on the starter is bad. try tapping starter with a hammer (lightly) to see if it engages and try starting again.

 

I get zero response when I turn the key from on to start. Nothing !

 

Check the connections to the starter. The big wire should show 12v all the time, the small one 12v when key is on start position. Also put one lead where the big wire connects to the starter and other lead to the positive on the battery. Should see 0v when key is on start. If it checks out good, replace/rebuild starter. If not, fix those connections.

 

5.9L starters go out w/ no notice have that checked

 

Thanks, I'll check it out. You guys are the best

 

Well after replacing the starter it cured the problem. Thanks guys for you help
