It took a while before it restarted and the motor does run smoother and I have considerably more RPMs it seems. I haven't actually drove it yet though.
Won't stay idling runs for a few minutes then dies and then I can't start it right back up. I have to wait

 

What's missing when it won't start?? Spark, or fuel??

 

It seems like fuel, but honestly I haven't got that far
Actually if it's something electrical I'm screwed cuz I really don't know anything about electronics. As I stated earlier, I have a multimeter but I've never had the opportunity to be around automotive electronics to learn how to use it. Not only that, schematics are hard to follow because it doesn't look like the vehicle which is really weird to me.

 

Look at schematics as a "Map" that doesn't necessarily reflect reality. All the parts are there, and listed, just in kinda random positions.

Listen to see if the fuel pump runs when you turn the key "on" when it doesn't wanna start.

 

Really need a scan tool (I use a $27 ancel: https://a.co/d/buR0xwq ) to see if it dies when it tries to transition from open loop to closed loop, or if some other parameters are going weird.

 

This is what I have. Well, other than tools of course.

 

Watch the open/closed loop monitor, should be able to find it key on, engine off.... once you know where it is, (if that one will even show it to you....) start the engine, it should go closed loop in just a couple minutes. If it dies right after..... that might be useful info.

 

Open/close loop monitor?
It seems this one doesn't show that to me.
Where would I find that you showed the 310 and I've got the 410

 

I would guess under OBDII somewhere. Gonna have to poke around, and see what you can find.
