Have to hotwire my 2006 Dodge Ram 2500 5.7 (auto)

When turning the key vehicle won't start. I have replace the starter relay that is under the fender (fuse box).

There is a yellow wire connected on the starter. Running a jumper from that wire and connecting it to the hot of the battery (key in the on position)the truck starts.

What could be the problem?

Thanks for the help.

check under the fuel filter bowl. the wire runs down to the starter sometimes rubs on the metal plate that protects the fuel lines. just move the wire and see what happens. there is also TSB 08-021-06 which discusses flashing the TIPM (power module) good luck.

Sorry for not explaining properly

Sorry for not explaining properly…..
*The (yellow) wire that comes from the starter and appear to end up under the fuse box (under the hood near the fender). It seems to be connected to a relay. When attempting to start the vehicle I can hear the relay click but not start. I removed the relay and have a wire connected to one of the terminals there where the relay should sit. At present, I have the relay completely removed. From that terminal with my jumper connected – I tap the battery and the vehicle starts. That tells me that the yellow wire isn’t broken as I’m passed through that with my jumper (battery --> relay terminal with relay removed --> terminal to starter --> vehicle starts). I did replace the relay because I thought it might be that but it didn’t work? Just an FYI – I can hot wire from the starter to the battery or from the post where the relay should be connected to the battery. Once is starts it runs like a champ.

Captain Obvious Alert - I'd say the answer lie in whatever is suppose to trigger the relay.

How about the "in park" switch? Anti-theft key failed?

If you set the emergency brake and put the truck in gear, will it start if you hot wire it?

Have you checked for any codes?

A bump if nothing else!

There should be 4 wires going into the relay. Two are power, one is command, and one is signal to starter. You could have a bad relay. If you hear the relay kick then signal and one of the powers are good. Does the relay plug look like

777Custom – I replaced the relay and still no good.
I have some good suggestions:
1. Try to start in other gears (with a helper waiting with the brakes on and standing on the side of the vehicle
2. Anti-Theft is another
Yes, I have a remote start but it won’t start remotely either but it will start every time when I tap my jumper wire on the battery.
No codes are showing.

OK if you can jump it and start it at the relay. Do you have voltage at one of the other terminals? Or do you have a good groud side at one of the wires?

double check fuse 14 in the fuse box. other than that could be transmission range sensor, ignition switch, or pcm. good luck.

I know the last post on this was a long time ago, but I'm having the same problem with an 07' that just happend yesterday. Lucked out that it's sitting at my girlfriends parents house, just was wanting some ideas on where to start when I get down to work on it. I'm wondering what the problem was with yours?
