Well I'll be a blue-assed baboon. Cody's suggestion worked.

I unhooked the batteries, and just in case I checked fuses while the batteries were disconnected. All the fuses checked out fine. Hooked the batteries back up, and it fired right up and ran smooth.

I didn't even think about the chip thing. I'm constantly yanking it out and reburning it every chance I get to try new stuff out, but I didn't even think that doing that time and time again would freak out the PCM.

At any rate, I took it out for a test drive and to make sure the batteries got a good charge after all that cranking I did today. So far, all is well.

Thanks everyone for all the help and suggestions. Thank you Cody for getting me back up and running.

 

Geez, Curtis. It never ends with you and that truck.

 

Subscribing.

Curtis, YOU are one of the best we have here, and thank you for that.

I surely aint calling your AE (nor you for that matter) a liar, but seein as things dont seem to be adding up, perhaps you should try some of the simpler things being thrown out here. Check the oil level. Put a charger or cables on her. Easy, free. Just saying.

 

Dangit im way too slow........very glad she is up and running.

Blue assed baboon........

 

Well I tried to rep Cody, but FTE has me on timeout with repping him.

I think he needs a new title, like Jedi or something. He's like a freaking ninja with the Powerstrokes.

 

I tried to rep him but got the old spread it around first. Cody has helped me trouble shoot a bad chip issue before, so I didn't doubt what he was saying. Apparently you thought the same way I did and just disconnected the batteries, but since he said disconnect the PCM, and I've learned to trust his advice, I was wanting a clarification.

Since between him and his buddy, they could probably explain to us why this happens, hopefully he comes back and gives us some more insight as to what might be going on with the KAM. Usually in this situation we'd be telling folks to keep the batteries on a charger, so we'll have to file away the disconnect trick, although I'm curious if clearing the KAM code with AE will work.

Now everyone go and rep Cody.

 

Tell me about it.

I still have more repairs to do. That drive across the country popped up a few new problems. I have a new oil leak, and I'm not sure where it's coming from. It's not a bad leak, only lost maybe a quart of oil in 3500 miles, but I have a few drops of oil on the driveway now. Also, the front tires are chopping along the edges, so something is screwed up with my alignment or front end suspension (yet again, I've had to fix it many times already, including new ball joints, tie rods, etc). Also I now have some weird slack in the drivetrain that started up on the trip, and has been steadily getting worse.

So yeah, I have more work ahead of me. The no start issue was just icing on the cake to royally **** me off to no end.

 

I think if it ever happens again, next time I'll just pop the fuse for the PCM keep alive and see if that does the trick.

But yeah, Cody seems to be a natural at diagnosing off the wall stuff. He needs a few of these from me

 

Deserved reps sent.

Side note......Curtis, quit driving that quarter mile truck on the cross country tracks...

 

X2 on the reps to Cody, good stuff..

 

Very nice, I got reps to throw at him.

 

I'll try to make this as short and to the point as possible since I could take an entire page to explain what is happening.

First off. The TS Performance chip blanks, while VERY robust and reliable, do have a few quirks. The first is that the microcontroller chip on it is slow to boot. One of the MC's jobs is to use the input from the selector switch and perform the actual task of "switching" the chip's position. There is a penalty for that though; the chip does not always boot up in the position selected on the rotary switch. I learned this the hard way when programming fewer than all 6 positions on the chip. If I programmed one position, it was VERY common for the PCM to be "dead" (no WTS/Fuel pump). This was because there was NOTHING for the PCM to boot with due to no programs on 5 of the "positions". A quick off/on cycle of the ignition switch would fix it every time. There were times that the lack of information on the chip would corrupt the KAM and I'd get a rough idle, smoke, no starts, weird transmission operation, etc. The closer I got to having all 6 positions filled with a program, the less likely I'd have issues. So now EVERY chip gets all 6 positions filled, even if 5 of them are stock.

Heck, I was fixing to live tune a guy's truck about a year ago and it happened with the emulator hooked up. For the life of me, I couldn't figure it out until I realized that all the data was correct and present, but nothing happened. I unhooked the PCM, waited 10-15 seconds (it should clear instantly), and reconnected it....back to normal.

AE has an option in the test menu for KAM clearing, but I have yet to have it work. It may be a GM option or something. Clearing the codes DOES NOT clear the KAM.

Thanks for the reps, guys, but I'm just doing what I enjoy.

 

In case you get bored later (you've started other threads for that reason) I'd be interested in reading the full page explanation as to what is going on.

Thanks for the explanation Cody.

 

Good to know Cody. I usually fill up all positions on the chip each time I burn it, glad to know that's the best thing to do. Heck, I fill it up just so I can test multiple tunes, or even compare my tunes to Bill's What's funny is that sometimes I'll test some new things, find out they don't work at all, switch back to one of Bill's tunes, and drive it until I reburn the chip.

I'm still lernin

 

Glad you're up & running - Thats a good one to store in what little memory bank I have left,lol.
