hi tp,

i just checked mine last weekend; engine was running rich and i thought the cold start injector was leaking; just unscrew it and stick it into a glass jar then start the engine (in your case cold engine); it should spray fuel for about 10-15 seconds after you first start it (might be shorter since it's warm in florida)...also you need to cover the hole the injector came out of since you're creating a huge vacuum leak, otherwise the engine will not start (but the injector should spray anyway)...hope this helps
