when i start the car when cold it has no issue.
after it is at operating temp and shut it off and try to restart it it cranks with no fire, when you turn the key off and try it again it will fire.
took it to a chevy dealer and they said it did not happen for them. when i picked it up and drove 3 miles to a store went in, and was back out in a couple minutes, it would crank with no fire and started after 2nd try.
Has anyone had this experience before?
If a vehicle struggles with hot starts but is fine with cold starts, it indicates that there is a lack of fuel pressure in the fuel lines.
This could be down to a few reasons:
The reason why fuel pressure plays an important role in hot starts is that fuel has a tendency to vaporize due to the heat from a hot engine. To combat this, the fuel line is kept under pressure to prevent/reduce vaporization from happening.
This also explains why the vehicle starts at the 2nd attempt - during the 1st start attempt the system has had the chance to pressurize the fuel line and purge the fuel vapors present.
