First time post, nice site!

I have an 2000 Ford but we can talk about my truck later. My buddie was showing me his 03 Chevy and he swicthed Quadzilla stealth tunes from like 70hp to 165. The tuner gave an error and now the truck will not start.

We need to reset the ecm? Is there a process or some fuses we can pull? Please help.

Did you try to reinstall the stock tune?
Mine willl freeze from time to time and I have to unplug it, but never a no start.

Plug it back in. Turn ignition to ON. Try to install any tune.

Disconnect the batteries for 15 minutes. Then reconnect and give it a try.

Thanks for the replys! I ended up towing the truck about 1 mile to my house. Tried everything. First unhooked cables then removed info fuse for 3 minutes. No luck.
Second unhokked cables for 15 minutes no luck.

He is going to have it flatbedded to the dealer. Like I said tuner gave error when going from 70 to 165. No return to stock, no new tunes, just errors. Figures tuner was damaged because he leaves it in the center console all the time????

Thanks anyways!
