Attention: TDR Forum Junkies My friend has a 2000 Dodge diesel truck with a little more than 200K miles. On his way home from work and on the freeway, the truck just died. He got it off the road and towed home where we checked it over. I asked him how recently he has changed his fuel filter,, well,, he has never changed it. I checked it and really, it didn't look any worse than mine that I change every 10K miles. I tried to start it and noticed that there was a pumping noise every time he turned the key on; fuel pump I figured. I checked to see if the fuel filter bowl was filling all the way up, and it wasn't. So, $205 and a new pump is installed. Still no start. Cracked an injector and there's fuel coming out, but I'm not sure how to tell if it's the right amount or not. By now the batteries were getting tired so he disconnected them and trickle charged them over night. Hooked back up and tried to start; still nothing. Won't even try. Try some ether gas and it starts. Won't stay started so it looks like fuel issue to me. Now we are nervous thinking it's gonna be an expensive injector pump. But there's fuel when we crack an injector and attempt a start, so I don't know. I checked how to read his engine codes here on TDR, so we gave that a try. The only code was P1693. DTC Detected in Companion Module A fault has been generated in the companion engine control module. More searching reveals that the code refers to an error code being detected in another module. Without a code from the other module, I can't tell what it's referring to. BTW, what the samhell does DTC stand for?!
Anyways, his truck has a "Power Puck". We are going to remove it to be sure that isn't what's causing the trouble. Also, we are going to inspect all the connections to the computer modules that are attached to the engine block. I figure one of them is the ECM, PCM, or maybe some other CM I'm not understanding.
Does any one have any clue what the problem is from what we've done so far or what we can do to help isolate the problem? My friend is a great guy, family man, works very hard in construction and really can't afford to pay out much more than he has for the lift pump already replaced. Thanks for any help!!
