Guys
The Wife's 2000 Z71 5.3 starts great cold. It cranks and sputters before going when it is hot ( up to temperature ). I replaced the temperature sending unit and that did no good. The air cleaner has 20,000 miles on it but looks real good. The truck has 48,000 total and runs fine other than it does not want to start when warmed up. Acts a lot like vapor lock. My expertise was in the carburetors and I could get along with throttle bodies but have no experience ( yet ) with fuel injection.
