starting problem 2004 z71
my problem is if the truck is cold it starts immediately. If it is hot it will turn 10 or 15 times before it starts. I have replaced injectors, crank sensor, fuel pump, knock sensors, mass airflow , o2 sensor. It all started when i replaced the injectors. It also is showing po- 174. Cannot figure it out. thanks

typically a long crank after a hot soak is from fuel leakdown causing a flooding conditions. but yr not seeing that.
p0174 is fuel trim to lean. is this code from b4 the repairs or is it active now? if actvie now; engine at operating temp; check the fuel trim with your scan tool and idle and held at 2500 rpm. report for both bandk1 and bank 2.
