does ne one know if a disconnected ground would cause a b16a from starting? How man grounds are there, and where are they?.. My swap is done but won't start. Turns over but won't start (no fuel or spark). Fuel pump doesn't prime (no voltage goin to pump), no spark. Gonna check main relay, Not getting any errors, but check engine light stays on.. Light doesn't even recycle. Just stays on. Could low oil pressure cause this?

 

Sounds like it's your main relay.
