I cleaned all connectors and pins. Because of these repairs, the air blend damper door actuator failed (it broke the main gear inside). To repair that consisted of removing the entire dash, replacing the inaccessible part, and reinstalling the dash. Replaced temperature control dash panel. I cleaned all connectors and pins.
In the winter that car runs perfectly.
I am starting to think it's the VCM because the high speed blower setting on the HVAC will not run sometimes too.
Now I think it might be the spider and the MAX injector.
Anyone know how to tell for sure??
HELP!!!

PROPER TESTING WILL TELL FOR SURE.
But best to start your own New Thread/Post.
Saves on hyjacking expense.
And give all information on yours.
You have a lot of replacing but no metion of what has beed tested or what brand of replacement parts or why parts were replaced.
Have you tested fuel pressure?
Have you tested everthing when it is acting up?
Have you put it on a engine capable scanner and read out sensor data and checked for history/past /stored /present codes?
Remember not all problem will set check engine light and hold it on?
Any flashing check engine light when driving?
Does the check engine light come on key bulb check on and go off engine running?
Was your replacement parts AC Delco and Delphi fuel pump?
Auto matc AC controls or regular?
How did your repair break blend door?
