Grouped lots of Maintenance

That just might work, lol.

congrats!

 

Bore scope w/pressure test...

 

When taking pictures of the cooler interior, you really need to override auto-exposure, or get some kind of penlight source aimed into the interior.

Car won't start and you've got CHECK HYBRID SYSTEM alert? Can you see hybrid battery charge status, and if so, what's it showing?

 

Most likely you have something disconnected or your new catch can system/hoses are leaking.

Second possibility is you may have pulled the orange hv disconnect and failed to push in the interlock after you snapped the handle in.

Independently, your hg problem probably is still there regardless of the egr state. You really need the dual view borescope test which was promised early but apparently not done as part of the conventional $250 tests. Those tests are not conclusive on a gen3.

98% the engine is not actually starting but it sounds that way as MG1 spins it at high rpm. The pcv is one of many things disconnected that will cause this.

 

First, stay calm.
If you had used oven cleaner, you could have saved yourself 5.5 days....
Did you clean the egr holes in the manifold?

It's extremely likely you just forgot to install something.
Double check EVERYTHING. Each connector, and hose filling.
This happens to a lot of people and 99% of the time they forgot to connect something.
GO SLOW, check everything, every connector and hose.

Did you remove the orange safety plug for the hybrid battery? There was no reason too.
But some people do, they even disconnect the 12v battery.
There is nothing related to the hybrid battery for the egr system.
Check that everything on the intake manifold is connected. It's sneaky and tricky.

I don't understand this: "Is this the first and second battery sections discharging?"

 

Since you installed a CC, it's likely you left something loose. See post 30.
That's a big vacuum leak.
PLUS!!! Do NOT just keep trying to start it. The hybrid battery is low.
By letting it keep turning the engine over again and again, you're draining it.
If it gets too low, you will have another nightmare on your hands...

Find the vacuum leak first.
IF you MUST try starting it, be ready to turn off the car if the engine doesn't
start right up. You'll know it, because it sounds different then just turning over,
which is what it is likely doing.

 

Yes, the HV battery turns the crank until the engine "catches" and if it never does it can last around 10-20 seconds before it dies. Each try will take up a healthy portion of the battery, so be very mindful from here on out. If it does get too low you need to charge it, which is not difficult, but does require a charger (which will be expensive). I would be double and triple checking everything visually before even attempting another start.

I don't think those tests are always particularly effective on these cars unfortunately. Visual check with a boroscope in the cylinders is generally the preferred method for 100% confirmation. People say you need to pressurize the system, but (if the car runs) you can let it pressurize itself and then just wait a while until you check the cylinders.
