Plugged head ports and I've got a bunch of issues I've never had before crop up. Cars been down since January so I'm finally trying to start it up.

Yeah twice I'll try it again. I did the hold to floor thing also. Oddly, when I clear codes while it's running it misfires a bunch.

I did the flex fuel install today and seems I'm having a similar issue:

With the exception I've got some camshaft codes also. I'll take another look at the pins tomorrow and hopefully my battery will have charged a bit.

Just got a brand new H8-AGM battery from Advanced Auto Parts. Same problems. I also flashed back to the literal stock file on my car.

Currently:
2A9E - DME: Camshaft sensor, inlet, synchronization
2A9F - DME: Camshaft sensor, exhaust, synchronization
2ABD - DME: Boost-pressure sensor, overrun (this is new, maybe due to the 3.5bar tmap
2ACB - DME: DME master relay, activation (I thought this was due to the trans fan I added to the DRLs, but I'm beginning to wonder more)
2CFB - DME: Throttle-valve adaptation value
2D09 - DME: THROTTLE.
2DEB - DME: Power management, vehicle electrical system
3100 - DME: Boost-pressure control, deactivation

Also a couple codes for the fuel level sensors because they are unplugged.

I was getting a buzzing from the HPFP, but it turns out that is because my LPFP was unplugged for all the work I was doing and the HPFP needs fuel pressure apparently or it makes a buzzing sounds. Figured that one out courtesy of an old post by @The Convert

I've put the flex wiring back to stock and I put a multimeter to the throttle body harness pins. Getting between 3.x to 4.x volts on various pins. I unbolted the throttle body and it doesn't move when I watch while someone keys the ignition without starting.

Has anyone ever received the 2ACB master relay code before?

I've been told that people with similar issues have fixed this problem by replacing fuse F37 and also the K6300 relay:

The fuse F37 seems to be fine, although I can't find my fusebox diagram to confirm. The K6300 relay is apparently on the back of the fuse box which means I have to tear into my car again while its already torn apart.

Based on the diagrams from TIS, shouldn't I be able to test pin 2 on X60003 of the small DME connector and know if the relay and fuse are good?

Problem has been fixed, all codes have been resolved by changing fuse F37. I checked earlier but looked at the wrong diagram, I needed to locate and check my own fusebox diagram.

This fuse and relay X60003 power a bunch of sensors and apparently the throttle body relies on it. Without starting the car, I can now see the throttle blade twitch during ignition on.

Has your car ever ran with the ST? Not trying to be a dick, honest question. It seems like it's constantly broken down and you are tinkering with it.

Main issue is my motivation to work on it is usually outdone by my interest to change things. Coupled with waiting for product releases, it's basically the perfect storm to be constantly torn apart.

But no, I don't get to drive it much and it sucks.
