Default Need help with lh2.4 swap

I did an lh2.4 swap on my 240 the other week. I am having an intermittent issue with it where sometimes it will just crank and The fuel pump will not prime nor will I get spark. Earlier I had it running, shut it off to fill with water, tried to restart it and... same issue. 30a fuse to ecu’s and fuel pump is good, I re-checked any wiring I did and it all looks fine. I have all the grounds connected up, too. What should I check?

Fuel pump relay, or spin the fuses.

Check the codes? Crank sensor?

And the ignition module. Without the spark signal you aren't going to get spark at the plugs or fuel pumps.
