Best way to disable a cold start valve?

I need to disable my cold start valve and I have seen pics of people who have done it, but I'm not quite sure exactly how to do it. Anybody done this? If you haven't removed it and plugged it, then what would be another good way to disable it?

Easiest way to disable it is to pull the plug on the injector itself or on the thermo switch on the intake. Also anyone know of a good blockoff kit for the injector hole in the intake as well as a cap for the end of the fuel rail??

Accel makes a kit to plug the hole. I wouldn't unplug that switch. It is also usede for fan control, so unplugging it may render your cooling fan(s) inoperative.

You can buy them on ebay or several performance shops online. I just kept mine connected but unplugged the injector itself.

Picard out...

I need to disable it to because I bought a super ram and there is no hole in it for the cold start injector.

I disabled mine years ago. I used a coin, a quarter I believe, and some sensor safe silicone sealant. I used the coin and the plate that normally would hold the injector to the intake manifold.

I did the same thing with the exhaust tube that use to run from the #8 header pipe to the intake manifold (86 Vette setup). In that case I used a dime.

Both have worked fine for years.
