1990 Eclipse GSX switched to speed density and now won't start. Briefly idles low and rough for a second before cutting out. I did boost leak check and found no issues, had and fixed fuel leak at AFPR fitting and oil leak at turbo feed line. Mechanically no other observed issues.
car ran perfectly with NO SPEED DENSITY & Walbro 255 rewired, AFPR, MBC, O2 housing back exhaust 3", DSMLink at all stock parameters, and stock 37 psi fuel pressure, AEM boost, wideband O2, water temp, oil pressure gauges
car now won't run WITH SPEED DENSITY & after MHI 16g upgrade, FMIC install, new intake pipe, catch can, 1200CC injectors high-z, resistor pack delete, ECMLink SD cable, GM IAT, Omnipower 4bar, EGR block off, emissions delete
It was a lot of upgrade at once along with the SD conversion but I'm reasonably confident of correct installs. Literally any info is helpful, I'm struggling.
Log 1 is first crank attempt
Log 2 is second crank attempt
Temporary FMIC mounting solution
