I hooked up my code reader and it would not power up.i also noticed the radio wouldnt come on.the truck cranks over fast but will not start.the truck was running great the day before.i have a 2000 model truck like this one and where the code reader plugs into the truck the bottom right pin location has 12 volts this truck does not.any ideas and thanks in advance tommy

 

It's the iod (ignition on display or demand I think) fuse. Are your dome lights turning on? It's the fuse inside the cab fuse box with a plastic cover, I just pried mine out but apparently there's a technique or someway to get it out. It's just a mini 10 amp I believe.

 

chadhager03,thank you for the reply. I will go replace that fuse.Any dea why that fuse would blow? Tommy (and no the dome lights will not come on.)...I changed the blown fuse code reader ,radio,domes work.Pulled the codes 1693,1698,0336,1689,0237,0222 cleared these codes and tried to start truck would not start.Engine light came back on,checked codes again had a 1693 and 0222 only. Any ideas on this? Tommy

 

Mine blew because I put my jumper cables on backwards but other than that idk

 

P1693-The companion engine control module has shown a fault.

im not sure if this means u have a bad ecm or not but if it does it might throw codes even when there is nothing wrong. one of my friends has a 1998 dodge ram that said his tps was bad his camshaft sensor was bad and his iac was bad. we replaced the ecm and 50,000 later (ish) nothing has poped back up. i would bring it to your local auto repair and have them take a look. it'll cost but it'll save you from putting parts in that dont fix the problem.

 

Forget clearing codes with your "code reader". Disconnect the negative battery cable and turn on the headlights for 30 seconds. Turn the headlights off and reconnect the battery cable. See if it starts. If not, do this and see what codes come up. https://dodgeforum.com/forum/2nd-gen...code-list.html

 

Poured a little splash of gasoline in the air intake and it started right up.No problems since. Thanks to all for your advise and tips. Tommy

 

I have a 2002 dodge diesel , 2500 5.9 liter my radio will not turn on! checked iod fuse its good everything else is fine. Checked all connections they look fine it was professionally put in hasn't been messed with ! Cannot get power to it HELP!!!

 

Grab the 01 service manual from here. Your truck should still be first gen. There is another fuse for the radio, I do believe. Anything else not work?

 

Take it out and check for power at the back of the radio, many aftermarket radios have a fuse as well that could have blown. If you have a blown fuse keep in mind that they don't blow for no reason, they also don't wear out, so don't change it unless it's blown.
