Where to buy new Cold Start injector for V6?
I have a 1988 V6 2.8L Firebird. I'd like to buy a new cold start injector for it, but I can't find one anywhere online. Anyone know who sells them new? I've seen some listed for the 305 and 350, are they the same one's for the v6?

If it is like the V8 version, apparently they aren't available new anymore. You'll have to look for a good used one, or block it off.

Odd that it would not be available, seems like a pretty critical part that aftermarket would want to build

For less money you can get a block off kit and a custom PROM to delete it. Fewer parts to fail in the future.
The aftermarket isn't interested. Too specialized and people just delete them so even smaller market.

I don't really understand how the delete works. If you delete it are you not getting the extra fuel needed that it is suppose to supply when the engine is cold or does the delete remedy that in some way?

The later 3.1 engine did not have the CSI.
So you plug the holes and get a chip with the later programming to use the 6 primary injectors for cold start.
Then you don't need it.
It's the same process as with the 85 to 88 tuned port V8. Since you can't buy them anymore, the community has figured out how to eliminate that early system. Just like GM did.

Re: Where to buy new Cold Start injector for V6?
OK couple of more questions. I'm assuming I can just disconnect the cold start injector switch and install a 1989 prom. Do I need to program the prom or will it work out of the box? Also if I install a new prom for an 1989 do I need to upgrade the calpak too?

You should contact member "Tuned Performance". He can set you up with a prom. I'm not sure what year you will need. If it has to come from a 3.1 then it will require more than just swapping chips. And I don't know anything about the V6 injector sizes, etc. If it's like the 5.0/5.7 you have to make a few tweaks like injector size scalars, and some mapping.
