Satsuma Cranks but won't Start

[Deathica]

So I spent a bunch of time prepping before building my Satsuma, bought all the aftermarket parts and 100% replacement parts from Fleetari's, I did all the wiring, engine building, installation, etc, and got ready to take my Satsuma out. Did a quick save, and went over everything in MSCEditor, did a couple tweaks on some conditions that should've been different, and for some reason, no matter what I do, the Satsuma will not start properly. I've swapped to brand new spark plugs, uninstalled and reinstalled the alternator, distributor, starter, the steering column, and emptied the fuel tank and refilled it, still nothing. Using a battery from Teimo's that shows no issues on its own. Genuinely at a complete loss at what else to try, besides rebuilding the whole damned thing from scratch. I checked every bolt in MSCEditor and manually unbolted and rebolted a lot of stuff, including the starter wiring bolts. MSCEditor reports 0 issues with any bolts or wiring, and shows good across the board in the Satsuma report. What else can I even do?

EDIT: Mod list is as follows:
Actual Mop
Attachable Roofrack
AttachJackandTriangle
ColorfulGauges 3
Engine Info
Fuel Cover
Gifu Gauges
GT_Interior
GT_InteriorDD_Patch
HayoPickup
HayosikoColorfulGauges
JackStands
JugWoodCrates
KiljuSellingFix
MechanicsCrawler
ModShop
MOP
MosquitoKill
MscModAPI
RallyLights
Repairable_Ruscko
Satsuma X-1
SatsumaDigidash
SteeringCap
TireRacks
Toiveradio Enhanced
UnderGlowKit
vuMeters

Only mod that majorly changes the Satsuma that's different than the last save I had where I got the Satsuma running is the Satsuma X-1 mod.

there are many things that can be wrong with it. so i will have to ask some questions about certain parts.
-does the dashboard lights up when you put in the key? and if so does it also make a cranking noise when you hold the key?
-did you tuned the engine parts? and if so what specificaly?
-is the ignition coil wired?
-are the sparkplugs tighten?
-are there any remaining parts on the shelf?
i may later ask some questions but if you feel like you wanna skip the chat you could provide the savefile of the game.

Dashboard lights up, all power related systems work, lights, wipers, etc, and yes it cranks. I tuned the twin carb, the rocker shaft, the distributor, and properly positioned the alternator. Ignition coil is wired, sparkplugs are tighten properly, there are no leftover parts that can be installed in my setup. also I can upload my save file, I wasn't sure how it would work with it being modded

The car detects you're a filthy furry and refuses to start
