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.

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