Hard starting


Do you hear the fuel pump momentarily when you turn the key from LOCK to ON? If not, continue...
If not, check the INERTIA CUTOFF SWITCH (especially if the car has been bumped or in an accident), and reset as necessary.
Also, if you did not re-pressurize the fuel system when you first changed the fuel pump, do the following:
  1. Turn the key from OFF to on. Count to three.
  2. Turn the key back to OFF. Count to three.
  3. Do 1 and 2 above, again.
  4. Do 1 and 2 above, one more time.
  5. Try starting the vehicle.
If the vehicle starts, you're good.
If the vehicle did not start, check the fuel pressure at the fuel rail, and replace the fuel pressure regulator as necessary.

Trouble Starting


sound like either leaking injector or failing fuel pump/check valve

cannot diagnose with a scan tool because you need to run a power balance test

however, being that the vehicle is 8 years old, I'd shoot for the pump first.

to confirm leak down you will need a fuel pressure tester installed before you shut the vehicle down, then wait a few hours and check fuel pressure before turning the key on. fuel pressure should be withing a few psi of what it was when you parked the vehicle
