Hello!
I need to replace this part. It is number 100 in the pic (Valve cold Start). My car is a Fiero GT V6 1986 AT

Does anyone know where I can get it? The Fiero Store does not sell it
Thank you!

One of the forum members will have one I am sure .GM used the same cold start injectors on other cars so should be available at wreckers.

I hope someone can find it for you. Not even 10 years ago, I wouldn't have been concerned at all... but I'm realizing now as I get older, that literally parts for these cars are starting to become really hard to find. Your last option is to remove it and have it rebuilt by an online fuel injector shop (which is at least an option). I just spent like 8-9 minutes searching Rock Auto, eBay, and even the equivalent Bosch number for it... couldn't find it. Doesn't mean it doesn't exist, I just couldn't find one.

1985 - 88 corvettes use the same injector and they are still available at most injection shops. I gutted mine and use it as a manifold plug as i have sequentia injection and had no need for if. the port for it on my fuel rail now has a fuel pressure sensor for my ecu.

Or you could just plug the whole and remove all of the cold start injector stuff. Just another option.

Thank you all for the answers. I finally decided to remove it

Just curious, how does your car run when you first start it, with it plugged and disconnected?

Also, I just noticed you are from Argentina. My mom was born there, in Buenos Aires too. They left during the Peronista regime, but really cool country.

In a warm climate, the cold start injector may not even be necessary.

I've never experimented with mine, but maybe on a cold day next winter I'll unplug the cold start fuel injector switch on my Formula to see how much more difficult it might be to start the engine.
