Default H22a4 CB7 Help

Hey guys, new to the page and H series. Just recently did a H22a4 swap inside my 91 cb7 coupe, motor came out of a 98 Prelude. I used a lot of my F22a1 parts for this swap, as in motor mounts (of course), stock wiring harness (I know you have to wire vtec, knock sensor, iab, and so), plug and play distributor, stock injectors, chipped p28. The motor is cranking but not starting, it feels like it wants to start but just doesn't, I have fuel, spark, compression, and timing is good, made sure distributor wasn't 180* out. I have full power and everything just won't start like I said I'm new to this guys, please anything to help, just need my car running. I have no CEL and just a battery light, dash works, everything works just not motor.

you confirmed the plug wires are routed correctly?

where did the chip/basemap come from?

you say you have fuel. fuel pressure? did you confirm injectors are "firing"?

If your crank sensors are hooked up and reading properly, then re-verify your plug wire firing order.
On F series engines the firing order is clocked different between Hitachi(internal coil) and TEC(external coil) distributors. With the body of the distributors facing the same way the rotor will actually be 120° off between the two.
Tower pattern wise, tower #4 is really #1 and #3 is really #2.
Put the engine on #1 firing(red mark) on the crank pulley. Verify it is #1TDC and not #4.
Pull off the distributor cap.
Verify that the rotor is indeed pointing to the tower that you have your #1 spark plug wire on.

What distributor and what injectors did you use?
