Store NSX engine for a year and half and now it won't start

[car2n]

Hi, I have an Acura legend with a NSX engine, I left it sitting in my garage for about 1 year and a half, before storing it it was running just find even started a couple of times during this period, now is not starting it cranks but it won't start at all, I am in the process of running a full diagnostics and troubleshooting of the engine, but I have a question if anyone has stored an NSX for sometime and also have and starting issue and maybe have some advice on what went bad during storage.
Any comments will be appreciated in advanced.

Tell us about the gas that was in the car a year and a half ago vs. the gas that is in it now. Same gas? Or was the tank drained for storage and recently refilled with fresh gas?

Otherwise my money is on a relay or the ignightor. But there are plenty of smarter people than me on this site.

your trying to tell be your legend has a nsx motor? C30a or c32b? doubt that very different to your legend motor but would be checking fuel as suggested and spark. needs both to be in good working order

Yes it has the C30 and also has an after market ecu, will check for spark

if so check all the grounds and connections as the ecu may have failsafes for no signal from some sensors

Injectors have probably seized from the dried up fuel. have seen it happen a few times.

Give them a tap whilst cranking and they will free up. I would then get them cleaned and checked as sometimes they don't recover and don't spray properly

OK I will double check all grounds and connections just to reduce options tks mr envy

You think all 6 got stock? But will try that because it's has to be something like that, something simple since it was park running no issues... Tks

I got news, after checking all known basic NSX engine troubleshooting with no luck, I went and pulled out of the closet Oem ECU installed and tried to started but battery was drained already but it felt like starting so recharged battery and "voilà" it returned to life again... Thank God it wasn't the EMS I am so glad.
after that I went and reinstalled the AEM EMS and starts and runs good now need basic engine maintenance and I guess starting the engine at least once of month...

thanks guys for helping with your comments!
