Did you test them individually, or test for voltage across them?

 

Individually

Is it possible that I’m just not getting power to the ecm/pcm?

 

check fuse # 20 25amp in the engine fuse box. power from this fuse feeds the ignition switch to the control side of the starter relay.

 

Checked, it’s still good

 

I think fuse 9 in the block on the side of the dash feeds power to the PCM, check that one as well.

Ooops. wrong year truck. There is likely an ecm fuse in the fuse block in the cab though.....

 

There’s no fuse box in the cab though, just under the hood. Or it’s not shown anywhere in the owners manual.

 

Ok. That shouldn't surprise me. Dodge never changes anything, right?

Check the one under the hood then, there *should* be something labeled for ecm/pcm. I would seriously consider changing it, even if it looks good.

 

to clarify...you have a no crank condition, correct?

if you have power at the fuse but no power at the starter relay pin(key in start)... the problem is between the relay pin and the fuse.
I would start at the ignition switch
red wire pin 4 should be fed from the fuse...check for battery voltage
yellow wire pin 13 should have power out with the key in start

 

I think the one you’re talking about is the engine control relay, because I can’t find an ecm relay, and this one is number 20. I checked voltage going through and it is still good.

 

I checked the yellow wire pin and it has power going to it, but I couldn’t find a good way to check any of the red wires while they were connected. I tried sticking my contact stick into the wire but I didn’t get a reading while in start. It could be that my method was bad, or the ignition switch could be bad too. I could try and replace it, its only about 20 or 30 dollars. I may have bad contact there because it only dings at me when I press on the key, not just while the key is in.
