OK. I had a previous post "hardly runs" and i got a lot of good info from you guys. BUT.. Truck still not running. I get the 1316 code. I have replaced the cam sensor, the icp sensor, the ipr sensor, the vc gaskets, the uvc harnesses, The plugs on the engine harnesses for the vc gaskets, and today i just replaced the idm module. I still get the same result. i get #1 #3 #5 #7 not contributing, and #7 short to ground. I have ohms tested from the idm plug to the injectors and got 2.7 ohms on all injectors but #7 and i get 2.1 ohms on that one. Buzz test sounds good on all injectors but is a little weak on #7. What am i missing? I did get a 0605 code one time, but doesnt show up every time. Is that a pcm problem? Sometimes it will run fine for a few seconds, but then it is like it shuts off one side.. Anything else???

Yes.

DTC: P0605
Circuit index: PCED
Problem: Internal control module ROM error
Probable cause: Internal PCM failure

In other words, your computer is probably toast.

It happens to the best of us. My PCM went south late on a Friday afternoon when I was 120 miles from home dragging a fifth-wheel trailer after a long trip "back east". Total bill out the door was $562.79, plus a $100 towtruck bill plus 3 days in an RV park. We rented a car and drove home to get our car, then turned in the rental car the next morning. So the rental car part of that bill was only $33.

A Good Samaritan saw the trailer off the I-20 service road and towed us to a nearby campground and, wouldn't take any money for his good deed. So Darling Wife sent his wife a dozen roses. And that cost me another $75 or so.

So have your checkbook ready.

Is it possible that the pcm can shut down just one bank of the motor? I was understanding that the idm was in control of all of that.. Where is the division between them then?

The service guy at my local dealer said that it must be the idm. Even though i already replaced that damn thing. He said the computer sends singnal to idm and that is what distinguishes how the injectors fire. This doesnt seem right to me, but i have never seen a pcm intermittely shut down just one side of a motor either. Anyone ever heard of the computer doing this before? I would like some more oppinions before i spend more freaking money chasing my tail.
