I did want to attempt it with the stock ecu to be sure,
What did I miss? The stock 2001 ECU is not tunable.

I think he means to swap the standalone ecu out with the original 01 ecu, put back the stock injectors and seeing if the car will start for troubleshooting purposes.

had a client at a different shop do this as he was having a similar issue with an aem infinity back in the fall. I think it eventually got resolved but he never told me what it was.

Apologies for the delay been dealing with weather in CT, I’ve had just a bit of movement here.

I’ve since tried hard wiring my crank and cam sensors directly to the ecu, which I think helped since I have no more codes and trigger errors have gone away it seems
Tried reloading the file and still a no start

Yesterday I did a live call with a haltech rep who looked at all the maps and said it was getting a ton of fuel.
I pulled the plugs and they were soaked w fuel
currently have them drying out now
also smell good hint of fuel on my dipstick

My assumption here is that it’s just flooded now?
The cam/crank position sensors being pinned incorrectly to the harness could have been causing my no start issue before but after repair still no start bc system is flooded, this is my top guess

any good tips to go from here? I planned on letting the plugs dry a good bit and trying again with some starter fluid help

I was also thinking about contaminated fuel being possible as well, I know I added 93 around 6 months ago but this was on top of a tank with 1/4 gas that’s been in the car for close to a year at that point.
I know I’d be better off flushing out my oil as well
