 Chevy SilveradoDifficult to start, I have to crank the engine 3 to 4 times.
Fuel pressure ok, new fuel filter installed.
Is there like a throttle solenoid or something causing the problem? thanks


Possible Causes:

  • A leaky fuel pressure regulator
  • A small vacuum leak
  • Intake leak
  • Sticking IAC valve – most common

We are assuming the check engine light is not on.
