Hello I have a 2005 AC 4x4 400 and it wont start. Turn the key and the solenoid clicks once. The engine does not crank. . I replaced the battery, replaced the solenoid, replaced the relays, replaced the diodes, pulled the starter off and checked it, it turned fine when hooked up to a battery. No blown fuses. Lights work and gauges work, light up fine. Now Im at a stand still. Any help would be appreciated.

 

cables?

 

Does it pull start?

I have had engines that guys claim the starter is out and go to replace it and other stuff just to find out the cylinder is full of gas/water etc. so pull the spark plug and take a look.

If it turns over but won't firs then it s an electrical issue. THen you need to start checking the rest of the wiring harness for a shorted out wire or an unplugged connection. Most of my connections that come unplugged are at the base of the steering column.
