Advice needed desperately here.. car won’t start

alsrn1492 · 12-20-2019, 06:50 PM

I have a E93 N54 335i with about 116xxx miles.
Injectors (index 12 FCP Euro) - 1000 miles ago
HPFP - 1000 miles ago
LPFS - 1000 miles ago
Coolant tank - 1000 miles ago
Throttle Body gasket - 1000 miles ago
Used Tranny with 45k miles - 1000 miles ago
Vacuum lines - 4000 miles ago

The codes I already had:
2D2E Throttle valve angle
30FF Overboost
3100 Related to 30FF

I have attached a picture of my codes I pulled this morning from my MHD Tablet.
Basically, my car will not start after cranking for a couple seconds. It would basically die out.
I took out the jb4 from the ECU and changed coils this morning, and my car won’t start anymore.
The only thing that I am really concerned about is that I totally thought I disconnected the battery while the battery was still connected.
Should I try jumping it first or is the car damaged to a point that needs to be towed to the shop?
My car had a misfire last night driving back from 200 miles round trip, and I had knocking (misfire I assume) when I did WOT on fifth gear.
My car recently developed 30FE code, and I changed my jb4 menu 11 or 12 that has to do with the throttle sensitivity and boost to 1800 rpm option.
The car is going in to the shop on Monday, but I am really just anxious about it thinking that I fu**ed something up.
Please, advice very welcome here

Not the first time someone has fried one of these cars with these stupid tunes and flashing and all that bs. Take the battery out and charge it then put it in the morning and try to start it. Nothing happens try to flash it back to stock with a battery tender or keeping track of battery voltage and pray

Have you tried clearing adaptations?

All those codes is an indicator of something fried. 2D2E and 2A9A are rare codes. Flash back to stock if you could because it doesn't even know what was flashed last.

Check the main dme fuse, the big 50a red one

there is an HPFP code listed could it be your fuel pump is bad?

Check your fuel pressure

2d2e is a vacuum leak. I just had that before my car was totaled from using an absolutely abysmal pos alibaba valve cover
