So i have a b18a engine with a vtec block on it and it had been working fine until a few days ago my ems said my car was runing n 100% and it went all berserk, once i got to stop i turned it on again it started on perfect, i tryed checking everything i could and it all seemd fine, after that i drove it 2 days later and once i parked it and turned it on again it wouldnt start instead would die half way, i changed my spark plugs all my oils are great, anybody got an idea of wat it could be? help plz >.<

 

Does it have spark & fuel to the engine?

 

I guess it would start intermittently... pay attention to the click noise of the main relay when your key to on position, if doesn't click then that is your problem.

Also like Civic said, check your sparks.
