Turbo mx5 help

hello, I have a 1991 mx5 turbo running a me221 which is currently not working.

It has spark ans fuel but I believe has an issue with the IAT or
the MAF delete.

I checked all the connection and the IAT sensor which all seem fine, the fuel pump stays on on ignition.

i tired plugging in the st fuse again and the car turned over. This was only for a second. The car doesn’t seem to want to run any other way.

Any any help would be great.

thanks!

Also, you're gonna get a ton of grief on this site because of your ECU. Sorry, it's not you (yet). Also provide a lot more detail about your build and experience level. Did you build this car? Is it a 1.8 swap that actually has a MAF, or is it an OEM 91 1.6 that actually has an AFM? Why is your first assumption that something is wrong with the IAT? What fuse did you plug back in? Were you not supposed to with your ECU? Many questions to answer before we can be of much help.
