2000 c5 corevette Slow starting issues
I just replaced my fuel pumps in both tanks and a new fuel filter, When I run on my engine I can hear it prime, but it still sometimes takes two attemps to get her to start, When she was new, she was quick to star I have purchased new fuel injectors as they are 21 years old. I purchased 8 OEM BOSH fuel injectors pt # 0280155931, 12482704, 12533952, 12554271
I also had the coils checked and only had to replace two.
So how hard is it to install them and what do I have to watchout for. thanks

No idea if this is related to your problem but there is a GM tech bulletin from May 2017 which includes crank no start And extended crank. It is 16-NA-383
Subject: Information on Rough Idle, Crank No Start, Extended Crank or Misfire Due to Excessive Carbon on Top of the Valves or Sticking Valves, Malfunction Indicator Light (MIL) Illuminated - DTC P0300, P0301, P0302, P0303, P0304, P0305, P0306, P0307, P0308 Set
This Bulletin replaces PIP5029H. Please discard PIP5029H

Do you start it right way with the key, meaning right to engine on? Have you tried letting the fuel pump prime a couple of secs in the key on position then try to start her? I know my 99 takes a couple of secs to start, especially the first start of the day as the fuel line builds pressure.....I have a new pump in my car and it may no difference with my original one...

Check your fuel pressure----Not sure if a 99 has a fuel pressure regulator on the fuel rail or if it is a returnless fuel system with the regulator in the tank---
Install a fuel pressure gauge on the fuel rail--turn the key on and see what the fuel pressure is---Also see if it "HOLDS" the fuel pressure or if it rapidly drops down---
The fuel rail pressure regulators are known to failure---and the returnless ones can fail as well but
require replacement of the intank fuel pump----
You should see at least 45 PSI to 58 PSI when turning on the key with NO START---
