95 Blazer Hard start when cold

[JasonSpaeth]

I thought about this. But I did not smell any gas on the dip stick...probably a good idea though.

Not probably, it is a definite thing to do when you swap them in.

The longer you wait, the more damage you are doing.

Help! I replaced my CPI unit and nut kit about a month ago. It solved the problem and has been running well. Recently, though, I have been smelling gas. Today, I removed the plenum and found puddles of gas on both sides. With the key on, I am unable to find any leaks. Where is this gas coming from? I checked each of the poppets and they are "clicked" in tight. Are these poppets susposed to have an Oring? - I don't remember seeing them on the old unit. Do I have a defective unit?

[BlazerLT]

No o rings for the poppets.

You indeed might have a bad injector.

Did you use o-rings for where the nut kit inserts into the injector?

[JasonSpaeth]

Yes...I used Orings between the nut kit lines and the injector unit. I just went and exchanged the CPI unit for another new one and installed it. Will drive it tonight and hopefully I will not smell gas when we return back into the garage. I also changed oil again in case it had gas mixed.

Trust me on this, also don't use a fram or pennzoil oil filter.

Hello,
I have a Lumina APV with a cold start problem also, and was just researching other posts when I read yours. I am curious: why not a Fram or Penzoil filter? What oil filter do you recommend?
Thanks!
