When my Z is hot, it takes like 6 full seconds of cranking to start. It starts fine when cold. The starter turns the motor fast, not the typical GM starter problem. I just replaced the injectors and valve seals. The injectors do not leak, I pulled the fuel rail and made sure. Anybody have the same problem and have some advice on how to fix it? I also have a very slight stumble when I am on the gas very very lightly, but now i'm just being picky!

 

I am a newb to fuel injection, but I found this.. https://www.thirdgen.org/techbb2/sho...ighlight=crank

How do I get my hands on the "solution"
