I have a 89 rs camaro that was stock with a 305 with a 5spd tranny. i recently threw in a 350 and wanna get rid of all the computerized stuff such as the vats key system, fuel injectors and so on. i basically want to have it as it was a old style camaro without all the eltrical crap. and help is appreciated. thanks.

Pull out the ECM from uder the pass side dash inside, and you're done. Won't get rid of vats. You can take out the wiring not needed that is in the pass side harness, but I'd leave it for now - you have a huge bundle of wires from in-cabin to the outside that you can take advantage of for accessories like fog lights, electric choke, manual fab switches, etc.

there is an article in the tech section. and here is how i did mine.

I noticed when the power to the ecm is cut off no power goes to the starter when i go to start it. how would i get around this issue?

Bypass VATS. There's a tech article linked from the thirdgen.org homepage that discusses the details of VATS.

Still not to sure on how to bypass the vats to get power to the starter. also what all is in my car that runs of relays? im wonder how big of a process this will be. I wanna take out the ecm, and get rid of all the relays can as well.

I didn't bypass my VATS, it's all in tact and operational - and mine starts just fine with no ECM (my whole ECM box is GONE!). I'm lost as to how you cut power to the ECM - if you pulled a fuse to do this, maybe that same fuse runs an ignition process. I don't know how to "test" for the swap working beforehand, I just did it, and made it work afterwards.

VATS will function without the ECM - no need to disable it really. But if you so desire, the tech article is here: http://www.thirdgen.org/vats_passkey_system & http://www.thirdgen.org/vats

And no need to hack up the wiring until you finish the swap and make sure everything functions - like I said it's been a blessing to have those wires from inside the cabin to outside the car - saves me from having to poke a hole in the firewall everytime I need a wire from inside to out - I just find an ECM wire that's not being used.

There are only 3 relays under the hood, one for the electric fans, one for the fuel pump (that won't be needed any longer), and one on pass side for the A/C system. So the only one that you can remove is the fuel pump relay, unless you run a seperate fan controller and remove the stock fan wiring (like I did).

I guess it all boils down to a JUST DO IT thing - if it's what you want. We'll help you get the bugs sorted out as you go. BUT - please know up front, it never happens in a weekend! I hate seeing folks that say "I have to have it done by Monday" - it's impossible. There's too many parts to be bought, ordered, changed, adjusted, tweaked, tuned, and such. Only if you have the keys to the Summit warehouse and do the job in there could you ever get it just right i a weekend.

I had taking out the ecm and just unpluged it. most everything works except no power to the starter and no fuel pump. I know this will not be a weekend job so im waiting to get the keys to another rig first. at this point i am just seeing what kind of work is entailed. i gues i will just rip into it when i get something to drive in the mean time. keep checking up on me to see how im doing lol id appreciate it.

I'm also doing a tpi to a carb swap and my check engine light is not on. Does that mean that there is no power going to the ECM? Is that why my speedo doesn't work? How do I supply power to the ECM?
