Re: Cold start injector (Steve87VETTE)
You might not have a problem in FL. The CSI has a very short pulse in warm weather and about 8 sec (I think) in really cold weather. Might have some longer crank times.
Just unplug it and see how it starts for a few days.
Question: why do you want to disable the CSI?

It's on a car I just put together and the line leaks at the fuel rail so it doesn't have enough pressure to start the car. I trying to get it running to work the bugs out then sell it.

Re: Cold start injector (Steve87VETTE)
On my 88 in 80 degree weather, when I unplug my cold start injector it has to crank for literally about 10 seconds for it to start.
Then again, there's probably something badly wrong with mine so you may be okay.

Re: Cold start injector (Steve87VETTE)
I'm curious why they ever needed a cold start injector. The whole point of a fuel injection system is to provide precise fuel control. I wonder why they couldn't get the job done with the other 8 injectors?

I think Jesse has been burning chips with programming to remove the cold start injector. Contact him(Ski_dwn_it) and he should be able to give you the run down. :cheers:

That just isn't right to begin with. :nonod:

Actually I haven't tested it since I got new injectors. Not really sure if it was because of my main 8 injectors (which were badly leaking), or if my cold start injector itself was bad. I'll give it a try one day when I'm bored now that I have my other 8 injectors.
If something can possibly go wrong on my car, it has.

Re: Cold start injector (Tourney3p0)
All you need is a new o-ring there. There's actually two pieces... a plastic looking washer and an oring.
Scorp, concerning the removal of cold-start, I've heard that the later vettes had it programmed in to pulse the 8 injectors more at startup.
Did they remove that thermo time switch on the front side of the intake base on 88-up vettes?

:yesnod: I had Jesse burn a custom chip for me after I put on my SuperRam which doesn't allow for CSI. Even with the custom tune may car takes 4 or 5 turns on the key for it to turn over.

Re: Cold start injector (chucks88)
I took mine out two years ago because fuel was leaking. I have not had a problem. Though I live in Phoenix, the winters still get down in the 30's. Still starts up, but does take some extra cranking but not bad at all. :cheers:

Re: Cold start injector (Steve87VETTE)
........speaking of cold start injectors........
How feasable would it be to somehow break into the cold start wiring to make a switch you could use at WOT to use the cold start injector for more fuel/power?
Or am I thinking too much again?
