I have a 94' Civic Si with a B16a swap in it.

The battery voltage is above 12.5 volts and NO CEL lights. When I try to start it sometimes it just dies out right after it fires up. Then when I crank it over again it just doesn't start. The engine cranks! it just never has a sustained combustion events.

This has happened before...like twice within the past 3 months and has rarely happened which i didn't pay attention to it.

I hear my fuel pump priming when i turn on the ignition but after the first no start, I didn't hear it.

If you guys need more info from me just ask.

Can anyone help?

After it dies, how do you get it to start back up? Do you just wait, or jump it or something?

I wait 1min then try, then 5min and try, after 10mins of waiting it starts

Does it crank and just not turn on? I had a similar problem with my buddys car i was fixing, it turned out to be a faulty ecu. Not saying that thats what it is, but if you have access to another known working ecu from a friend or relative, give it a shot. Did/do you have a CEL?

Yes it cranks and does not turn on...as i stated in my first post.

I don't have access to another B16 ECU so that's out of the question

No CEL
