Hi Scotty, you do a great job explaining what your topics are about on y-tube.
I have a 2000 dodge 2500 with a cummins diesel engine, 5 speed, 105,000 miles. I'm haveing trouble with it starting every now and then.. If I turn the key 3 time trick to get any codes it will give me 1693 code, I had a friend put his code reader on the truck and it sayed the truck has no codes, I'm kind of confused on that one?? I'll will start the truck up and sometimes it will crank and fire wright up but other times it will just crank and no fire.. When I do get it started and drive it awile the rpm gauge will go to 0 and stay there for awile, then go back to working after awile. When the tac is not working there is less power, but the truck never stalls when driveing after I get it started. When the tac is not working and I shut the truck off, it will crank over no fire till i hold the gas pettle on the floor then it will findly start. Could it be a crank shaft sencer??
It could be the crankshaft position sensor. But the fact that the truck never dies while it's running makes me think maybe the camshaft position sensor.
After starting, the truck will run if the camshaft position signal drops out.
The problem is, if you stop at the store to grab a pack of smokes or something, and then you try to start the truck it won't start without the camshaft position sensor signal.
And when they're failing both of these sensors are prone to "dropping out" when they get hot. They cool of a little and they work again.
So it's one or the other. Just buy OEM. People end up running in circles because they buy cheap aftermarket sensors that the computer doesn't like and the problem persists (or gets worse) and they think "well I bought a new sensor so that's not the problem"
