Noticed a couple of things right off the bat-

A couple of ignition codes I am assuming may be related to my remote start system but maybe not. Anyone in-the-know let me know if my thinking is off on this.
Codes detected-
B1360 Ignition run/acc circuit open
B1352 Ignition key-in circuit failure

I also ran an injector buzz test and it said test completed successfully, but no other information.
I did a cylinder contribution test and came up with-
P0284 Cylinder 8 Injector circuit contribution/ balance failure

Is that normal because of the issues with the stock fuel system starving number 8 a bit ? Or do I have a problem?

Oh yeah my voltage running idle with the ac on is 13.8-14.1 and the bar under the meter is yellow not green Does that mean a new alternator is in my future?

 

The ignition codes you are seeing are quite common on remote start systems due to the way the system intercedes with the factory harness. They're not much to worry about.

The buzz test doesn't really say anything unless there's a failure.

The CC test can indicate a false error on number 8 cylinder for couple reasons, although starvation is not generally the issue. Usually, the LL8 injector is the reason for the erroneous DTC but it's still something I'd keep an eye on. Are you noticing any idle problems or instability?

13.8 to 14.1 volts is perfect for the charging system. It's just AE's scaling that's off. If you're concerned, have your system load tested by a competent repair shop. That should help put your mind at ease.

Take care.

 

Thanks for the reply(I am assuming this is Bill seeing as how your wife has her own sign on- Groovy Chick) .

I am not noticing any idle issues. Seems smooth(as smooth as a mostly stock fuel system'd 7.3 can be anyway) and regular just like it has always been since I have owned the truck (3 years and 22 days ).

Glad to hear that the charging system is where it needs to be.

Thanks again, I appreciate your knowledge and information.

 

Jason, it is somewhat common from time to time for #8 to fail a CCT. If the truck is running good and not setting codes, then it's probably not much to worry about at this point. However, there are several reasons that could possibly generate the failure at #8. One instance is the grey recall CPS, as that has been known to cause failures at #8, and at times #3 also.

 

Well, I did just switch to the gray CPS back in April when I was having ICP issues. I had a spare one in the glove-box and thought it might help, so that's good to know Curtis.

 

Then that's most likely the cause, especially if you still have the LL injector in the #8 hole.

With a grey CPS, my cylinder rotational velocity numbers on #3 and #8 both increase, but without the LL injector, I don't get a CCT failure.

If you go to the live data menu, and pull up the cylinder rotational velocity for #8, it will probably bounce around the 4% mark. Usually above 4% (or hovering around there) is enough to cause a failure on the CCT. The thing to note, the cylinder rotational velocity can only be checked on a warm engine, and only at idle. Otherwise it will show 0% for all 8 cylinders.

That's just a test to verify that it's the grey CPS that's causing the problem. If you swap in a black one, the #3 cylinder rotational velocity will drop quite a bit (sometimes to 0%), and #8 will probably drop below the 4% mark also.

 

I'm still learning. That was actually the very first time I hooked the thing up, so I am not too sure how to get the live data to show anything on the cylinder rotational velocity parameters. I had it selected at one point, but it just sat there and said 0. The truck was warm and idling so I don't know what to think of that. Maybe I didn't let it idle long enough? Is there a minimal amount of time it needs to be idling for it to compile the data?. I was watching other things like voltage and accelerator position so I was blipping the accelerator every so often.

 

It should read instantly at idle. Just make sure oil temps are in the 160's or higher, that means it's warmed up enough.

BTW which cylinder was it that showed 0? There's a selection for each cylinder individually. Some will show 0, but it's pretty rare for all 8 to read zero, especially the #8 cylinder with a LL injector.

Also, if you get a reading of 0 on all 8 cylinders, make sure your chip is in the stock tune, then try again and see what happens.

 

Did you do the "key chime killer" mod? You will get a code when black w/pink stripe is disconnected or not grounded.

 

I did not do that mod Roland.

 

I actually was looking at cylinder 8 because I knew that would can show funny readings. I looked at a couple randomly and then specifically number 8, they were all 0.

 

Glad to hear you got it Jason, like I said earlier, they are worth their weight in gold, good luck.

 

My truck with the remote start sets off the same 1352 ignition code. Nothing to worry about

 

I'm still messing with mine too Jason. I'm embarrased to say that I've only hooked it up twice. I just haven't had time to learn to do data logging with it, and I really want to do that. I am hoping there will be a tech session at RRE on it, or at least someone there that wouldn't mind taking a little time to show me some things over a couple beers.

 

Had LL injector. Got Failure on Number 3 sometimes and #8 every other test.

Got rid of that LL injector. No change. Got this. (see pic)

Put in black international CPS. Now i only get failure on #8 once in a while. Maybe once out of ever 5 tests. #8 runs around 3Rv.. #3 runs around 1.5Rv.

Dads Truck. I put in Black international CPS. His runs all cylinders below 1.5RV. No LL injector (2000 PSD).Never fails on #8..

Why there is a difference between his and mine is the question.
