Need help to diagnose no fuel no spark

Alright guys so yesterday took the car to the track, car ran perfectly fine. Didn’t want to push it too hard so I wouldn’t have any problems on my way home (no trailer).
As I let the car take a break and cool down I started packing up. I go to start the car and cranks but no start.
No pressure from the pump, so I go to diagnose and the fuel pump relay wasn’t getting ground, as soon as I jump the relay to ground I had fuel pressure. So I crank again and no start. Found out I had no spark as well !!
I was carrying my obd2 scanner and when I plug it in, it doesn’t connect to the vehicle.

Diagnosed for about 2 hours at the track before giving up and towing home.
I searched here and other forums, with no real definitive answer.
It is a 97 with a ka24de.
I’m suspecting ecu problem, eccs relay, possibly distributor (built in cam angle sensor) or maybe some wiring problem between fuel pump relay and ecu. Checked all fuses and all are good !
But anything I may be missing would be a great help guys , cuz as soon as I’m off of work ima rush home and start poking around .

Thank you in advance

Update guys! For anyone having the same issue, I solved it in about 10 minutes at home...
I cleaned my ground wired on the head on the exhaust side, and I pulled the ecu, checked the eccs relay behind it, and the relay was not responsive, so switched it out with a working one and car fired right up
