my dodge ram 1500 2007 won't crank, engine will not start, checked all fuses and battery connectors they are ok but it just wont start

You need a voltage meter to check this and not a test light. You cannot tell voltage by the brightness of a light. Check the voltage on the large power wire on the starter to see if you have 12 volts. If so proceed to step 2. Have someone get in the truck and turn the key like to start and check the voltage on the starter solenoid. If you have voltage then the starter is bad. If you don't have voltage then the starter relay might be bad.

I just had one in the shop,i wiggled wires on back of fuse box n now it starts n runs
