2001 Dodge Ram Not Starting

Electrical problem
2001 Dodge Ram V8 Two Wheel Drive Automatic

When my truck is cold it will start normally. When it is hot it will not start. The engine will not turn over and there is no starter clicking as if it will attempt to start. I turn the key to start and nothing happens. The lights will work and all the instrument panels lights are working properly. Once it cools down for a while it will start normally. This repeats itself once it is hot and the engine is shut off. I have a brand new battery and there is no corrosion of the terminals. It has a full tank of gas. Could it be the starter relay or the fuel pump relay? What is your suggestion?

When the engine does not start while it is hot, connect a jumper wire betweenthe battery and the solenoid (S) terminals. if the engine crancks, there is a problem in the starter control circuit.
if the solenoid make a clicking sound, it 's operating properly and the problem may be with the starter.if no sound is heard, the solenoid is the problem.

If the solenoid is good, locate and check the relay.

The starter relay is located in the Power Distribution Center (PDC). Refer to label on PDC cover for relay location.

View of the battery (1) and PDC (2)

Disconnect and isolate negative battery cable.
Remove the cover from the Power Distribution Center (PDC) for relay identification and location.
Remove starter relay from PDC.
Check condition of relay terminals and PDC connector terminals for damage or corrosion. Repair if necessary before installing relay

keep me update.

The text and illustration does not indicate where the solenoid connection is at. So not knowing where the connection is at how can I put a jumper between the
battery and the solenoid connection?

Ok thank you for your patient.
Connect a jumper cable from the battery red cable to the s terminal(start) on the side front where battery cable is conneted to the solenoid. It is a small group of wire there coming from the ignition.
Jump it over there.
There a small wire from the solenoid to the starter.
It is a short small wire. Check it it if it fried or burn.
Because when burn up ( or hot), it will not transfer electricity and solenoid may not pass electricity to the starter.
