S2000 Won't start, I can't figure it out
A couple days ago my car randomly decided it wasn't going to start anymore. Saturday it started fine, no problems, then on Sunday I went to start it in the morning and it cranked, turned over for about a second and then died. That's what it been doing, I haven't been able to get it to run since. I have since replaced the fuel pump and MAP sensor and it still won't start. Just does the same, crank, turnover briefly and then dies. The spark plugs, ignition coils and battery are all less than a year old with about 11,000 miles driven since install. I replaced the fuel pump because I was going to replace it soon anyways because I'm not sure how old it was and the MAP sensor was honestly a shot in the dark trying to solve this problem. My S2k is a 2002 with 99,000 miles with no modifications other than a custom exhaust and a K&N intake. Any help would be greatly appreciated!

Turning over and cranking are synonymous.
The proper phrasing is fires up. As in, it cranks, then fires up for a second, then dies (or, it turns over fine, fires up, but then dies).
Any codes or cel?
What happens if someone else starts it, and you spray some shots of starting fluid down its throat to try and keep it running?
This will help rule out, or in, fuel delivery issue.
If it more or less keeps running so long as you feed it shots of starting fluid spray, you have a fuel issue. If no change, still fires up then dies, you can rule out fuel. Look elsewhere.

Is there a green key icon flashing on the dash?
Did you try a different key?

Could try another ignition relay if you have one you could borrow to test

I think the issue is probably the immobilizer. That's the green flashing light - an immobilizer malfunction.
The battery in the key remote is just for the remote. So...that doesn't matter.
Did something happen to the ECU that it would erase the known keys from memory? Or maybe did something happen to the keys to wipe their ID?
