I just swapped in a sohc vtec zc in, to my DX. I have no money so i'm still using the Dual point intake, distributor and ecu. I had the same problem, no spark would not turn on. The problem was timing. Only one distributor bolt, bolts on the new engine and I was trying to start it up holding it with some locking pliers. Well, after a few tries moving the distributor, I got it to turn on and timed it with a light.

My ECU isn't throwing any codes... Would timing cuz my car not to get spark? davcivic you said just to turn the tires, whats that gonna do?

you got the right dizzy for that app? i had the wrong dizzy on my 90 si mini me swap.. it was dx... and it wouldnt work.. find out what yr dizzy u need for that app..

Not tires, I tried a few times moving the distributor. The 3 bolts don't line up with the new engine. I bolted just one, the top one, then kept advancing or retarding time until it turned on, then adjusted the time with a timing light. But make sure you have the correct one for the ecu you are using

yes those grounds.

The ECU i'm using is my stock 91 Honda Civic Si ECU. Could this be why i'm not getting spark? All the ZC wiring hooked up except a couple of connections which i found out where they went and fixed those problems, could it still be the ECU? Thanks again.
