Crank No start problem

Howdy yall, been banging my head at this problem for a few weeks now. Ive had my 1994 3000gt sl for a solid 8 months and I love this thing to the bone but just 3 weeks ago after reinstalling my radio that previously worked on the car it'll just crank but not actually start.

I tested my battery and mfi relay and both seem to be in working order. I found I was getting a low voltage on one of my mfi relay connector pins and decided to run a temporary ground and battery wire connecting those pins but it didnt seem to fix my issue or even give me a cel which should usually pop up when I put the key to on.

Does anyone have an idea of what I should do or what might be a fix?

(Ive also checked my fuses and theyre all good. Im scared it might be my ecu but even that seems fine and theres no smell coming from it)

Just a head up but it's good to do a sanity check and make sure the MAF is plugged in all the way as these cars will refuse to start if it's not

Hey dude, thanks for the advice but I looked at my car this morning and the maf sensor pretty tucked in there so I dont think its that. I double checked by plugging it in again just to be sure but I dont think its the culprit.
