Newbie needs help!!!! Hello everyone. I just rescued a 98 Vette that was rotting away. The previous owner says it needs a new ECM and has some major waterleaks. The waterleaks I have under control. The ECM is a different story. I bought a ECM and had it programmed with my VIN. Installed it yesterday, dash lights up, turn the key, nothing. I can hear relays clicking but the starter doesn't even try to turn over. My first assumtion is VATS and needing to have the BCM reprogammed for the new ECM but I am not so sure. The security light is NOT on, it comes on when you first turn the key on and goes off. If my problem is with VATS shouldn't the light be on all the time? Does VATS keep the starter from turning over as well as killing fuel? Is there something else I can check?
I have already jumped the starter direct and it is working when it gets power.
The car sat for awhile with no battery in it and the previous owner has the BCM and inside fuse panel laying in the floorboard. (Chasing the water leaks.)
Any help would be great. Thanks.

It doesn't do anything. I hear a relay click under the hood that is labeled ignition in the owners manual but nothing else happens. I will go through all my ground points this weekend and see if that helps.

I'd check the most common ones that cause this. The three that are on the back of the driver side head. Also check the battery connections. If they are tight, take them apart and give them a good cleaning.
If I'm not mistake, the VATS is controlled from within the BCM. I'd be willing to bet that the BCM is bad. See if you can get a used one, but you'll need the right resistor for the VATS to work still. Good luck.
