Help! Cold Start Injector

[Ol'Scratch]

Howdy Folks!!...

I searched for "Cold Start Injector" and drew a Goose egg on results. I have a 1988 Corvette... We replaced the injectors (among other things) for a "hard start when warm" and "rough idle when warm"... actually we replaced FRV, EGR, IAC, ECM and lastly the injectors. Before we button her up, we eyeballed the 9th inj. and wondered.... if this is bad, lets replace-rebuild it-delete it in that order. The 2 numbers I have are as follows: 17080402, and 17110860. If we can't find one, who rebuilds them? If that draws a zero.... How do you delete the darn thing?...

Thanks Folks

a "hard start when warm" and "rough idle when warm"...

Cold start injector is only functional when cranking the engine over cold.
It can only present a problem to engine operation if it is mechanically faulty and leaking fuel full time ( testing required )
No CSI may give extended cranking on cold start in colder climates , there are work arrounds

. How do you delete the darn thing?...

Unplug the connector and remove the wiring back to the CSI switch at front of intake

If the switch is still functional, keep / sell it ; they are a $150 replacement item

There are block off kits available if you want to remove it and it's supply line to make your intake purty
