I have a Jeep that i put a sb350 and recently installed a TPI unit on it out of a 90' camaro my ecm# 16198262. I bought a harness from Techrods in Texas to run the TPI. I hooked it all up which was pretty easy. I have all new sensors and it's hooked up correctly atleast i think so. I bought a VATS bypass module from baker electronix that has both the 30hz and the 50hz. So i hooked everything up and tried to start it today. And NOTHING. I tried the other hz and still nothing. I sprayed starter fluid and it started right up and runs fine. So then i ran the trouble codes and it came out to a 43 which is VATS. I have done alot of research on it but nobody seems to have anything on VATS if you have the module installed and it still doesn't start. I read something about the ignition module being a factor but wasn't too clear. Does anyone have any ideas? Thanks, -Kyle

get rid of vats system u have chip in key right?

No i don't have the key or any of that, all i have is a new harness, TPI unit and the ecm.

It' a stand alone harness to run the TPI only.

Turn the VATS flag off in the code on the PROM.
