Yes i am running delete tunes and i also have it wired to the key on wire. I am not sure it was because i just installed the the newest update or what i am not having the issue now. Seems to start fine today.

I had the same thing happen to me. The computer only lets you do one ignition cycle in stock mode with out a DPF being present, then won't start again. Try tuning it again and it should start up. I went thrugh this on the phone with the guys from H&S.

between this and your gauge funkiness, you may have a hardware issue.

I have had two no-starts with my truck w/ the mini maxx. Each time I unplugged it while running, then killed the truck. Truck would not start until I reflashed it. If your HDMI cable or OBD block is shorting out slightly and causing the same signal as unplugging the HDMI, there's your problem.

I will say that the truck ran fine, the only way I noticed an issue was that the AC compressor wasn't coming on. So I shut the truck down and when I did it wouldn't start! :eek:

It started to day fine. Then on my way home my ac was not working. Just blowing hot air and the truck fan was kicking on just after starting after work. It's gotta be a program error or something I have nOt had any issues till I installed the latest update.

that's really strange. I would call H&S tomorrow, but in the mean time, I would go back to the previous version of software. They're the same firmwear, so no problem going back

Your not getting a U0073 code are you. Same thing i was getting but with the u0073. H &s sent me a new block plug and hdmi, mine was shorting out, throwing a loss of communication code.

I think it's only glitching out momentarily. Possibly not long enough to kick a code?

But the fact that it's losing the AC compressor function and won't start sounds to me like he needs a cable and or block

Mine would lose the ac, and the cruise, i bet he has the u0073 dtc. They say all it takes is a split seccond to throw the dtc.

Did you happen to check diagnostics at any point? We too believe you probably had the U0073 code. If you simply clear the code, the truck will start right up without re-programming. U0073 tells us that there is a communication problem somewhere. The most common causes are OBD Block and HDMI Cables. Sometimes they will loosen due to vibration or get bumped or kicked causing an issue. It could also be a faulty cable or block that was not altered physically.

Give us a call and a member of our Technical Support group will take care of you. We are available Monday through Friday from 8:00-5:00 MST toll free at 888-628-1730.

My truck had been fine for months and had numerous program changes between h&s and kem. All of a sudden one day i went to leave work and i noticed my exhaust changed tones and my air quit blowing cold, killed truck and no re start till i cleared the u0073. Was not a problem with mini maxx unplugged. Plug it in an problem came back, with kem or hs tunes. They sent me a new cable and obd2 plug and all is well.

Interesting. I guess there probably was a DTC. I was simply so panicked, that I reloaded the truck before running diag on it.

Sounds like a cable and/or block will fix it. You can rule out the cable if you have another HDMI cable at home. I've had a bad HDMI right out of the box. I've also had a bad block. H&S is always great w/ customer support!! They'll get you fixed up
