Need help to keep engine running!

[Kiquee71]

Running only a few seconds is almost always related to VATS module. Should have been removed from ecm. There are also add on vehicle anti theft bypass modules, which I have on my modded factory wiring harness.

Thanks jlcustomz As far as I know the VATS has been disabled and the anti theft also, but I have no way of verifying if that has been done. I’ve been dealing with a tuner with remote tuning using AutoCal, and its hard to do this cause I work and the car is at a shop so it makes it hard for me to be there and diagnose. Don’t really want to shop to mess with it either cause they charge by the hour and that could get pricey. They usually talk their customers into buy a new engine, ECM, harness etc to get away from troubleshooting these problems. I get it, but I don’t have deep pockets either. They also don’t have a go to tuner either. That’s what I’m looking for, someone to come in and hook up to the ECM and see what the issue is. Just to get it running. Know of anyone?
