I reloaded my working bin(factory w/ disabled VATS). after it loaded. I could no longer interface with the PCM. Even pulled out my Scantool to hook straight to it. still nothing.

but after learning how to enter recovery mode (and a few tries doing that) i was successful at recovery.
Those statements confirm what I've said.

I know this is a couple years old now, but my interest has perked again in the area of the 7603 bin. Just like before, i can load it up just fine. Turn the key and i can hear the fuel pump like everything is all hunky dorry. Try to turn farther to start and nothing happens. I'm wondering if the s-10 has another step to starting like foot on the brake of something like that. but since i dont have the BCM.... idk

Sounds like you need a neutral/park signal or a clutch safety signal. Are you manual or automatic? If so you may be able to turn the off in the bin. I'm not sure.
Try jumping the starter and see what happens.

I assume it uses a relay for crank. Jump the relay pins and see if it starts.

I'm assuming the p/n switch is fine since it works with one bin, but not on the other. I did jump over the relay. It spun over but no spark. Like the VATS were on, but thats disabled. I could be wrong doesn't a clutch switch sit in the same place as the p/n? I don't know. Will look at the schematic again. Wish I had a schematic for an 04 s10. Will look into that as well.

Hi all,

Even though you have disabled VATS, you may want to try doing the "VATS Re-Learn" procedure.
On my cars, it takes 1 10 minute key-on, engine-off cycle.
I THINK the trucks take THREE cycles. (My 1998 Blazer did, but it had a "Black-Box" PCM)
May be worth a try - definitely can't HURT!

found something interesting. I've been using EFILive to disable to VATS, but when i open said file with Tuner Pro the option is set to 1 which is not disabled but only a different VATS setting. When disabled with Tuner Pro, EFILive says "out of limits". I am trying it again in the truck with the Tuner Pro setting. Let ya know how it goes.

ok, when i disable VATS in Tuner Pro it causes a checksum error. "Error - One or more checksums could not be updated. Check checksum addressing, etc, for validity."

ok, found a few things in Tiny Tuner. set gear selector to none, set cluster to discrete wired. Not seeing anything else where it seems to be looking for a network

If you don't have "Universal Patcher" you need to download it. If you have any BINs that give you that Error it'll fix the checksum.
Just open the BIN with Universal Patcher and select "Fix checksums of current file", then save it.
You can use it to tune with also.
