FYI. Not all trouble codes will trigger the Check Engine Light. Some pending and historical codes may be stored in the OBD system. (if you haven't cleared them recently.)
You might want to pull the codes again and see if anything is there.

 

Yeah, I'm waiting until she gets home today.
My biggest concern right now is the hard starting issue after the car sits for hours.

I'm wondering if the coolant temp sensor is possibly acting up?

 

Your post just before. #96.

First you say you didn't replace the EVAP tube then a short time later you did.

 

Post #90.... Evap line replaced. Last weekend.
Originally when I replaced the fuel line, I did not replace the evap line. But after still having the hard start issue last weekend I replaced along with the host of other items.

 

I am really confused now post #90 is what I quoted, Clearly says "EVAP line-No change" at 10:03 AM 1/14/19. Then post #96 "replaced the line at 2:43 PM 1/14/19.

Are we talking the same thing?

 

No change by saying there was no effect on the starting issue.
I also changed the fuel pump, and it had no effect on the starting issue.

No Change= No effect on starting issue.
I probably should of been clearer with that.

 

To clarify the items I've changed thus far.
02 sensor (First one from engine)
Front Evap Solenoid
Rear Evap Solenoid
Injectors and Isolators
Spark Plugs
Fuel Pump
Evap Line
Fuel Line

 

You are to the point now where it needs to be connected to a live scanner to see whats really going on, unless, you like throwing money and parts at it.

 

I ordered a bluetooth OBD dongle and the Torque Pro app to see if it will help with some data. I have a friend that has a snap on that I could maybe take it to.

To be 100% honest, I'm not really sure what I should be looking for. But, I'll see what I can find out.

 

Do you know which Snap-on he has? The High end Snap-ons are expensive....... Figuring out what it's not happy about is the issue and the fact that it's kinda intermittent makes it even harder. If it would just not start it would make it easier. As FMG suggested some codes don't pop up. There may be something in the history, that is where the high end Snap-on may find it. I don't believe the Torque Pro will do it for you, could be wrong.

My wifes STS-V Cadillac is much the same way. It isn't hard to fix the issue once you know what the issue is. Fortunately I have a Tech II. Some of the modules are expensive and getting to them is a joy as well. They hid them all over the place.
