1995 3rzfe just quit running. Cranks but won't start

Truck was running great all of a sudden it quit like I switched it off. I have checked all fuses and grounds but have no spark or fuel and obd2 will no longer communicate.

(1) Welcome to CT!

(2) What were you doing when it quit? Did it die while you were driving, or did it simply fail to start one day?

(3) Does this Taco have any engine or fuel or electrical modifications?

Just died while driving no indication at all. Truck is stock 1995 4x4 with 3rzfe. Starting to wonder if it's the circuit opening relay.

A blown 7.5A STA (Starter) fuse might explain it. This would kill the Circuit Opening Relay.

The same could be said about the 7.5A IGN fuse and the EFI Relay.

A broken / bad connection to the ground point would also disable these relays:

EFI Relay = Ground Point EA (left / driver-side front fender; inside engine bay)

Circuit Opening Relay = Ground Point ID (behind the left kick panel)

If the ECM had detected a fail-safe condition that would kill the engine, but the OBD port should still work.

After a lot of checking and testing I believe I've found the problem. Leaking valve cover gasket leaking oil into distributor connector resulting in a direct short in distributor blowing 30amp A2 fuse. Without connector plugged in fuse doesn't blow and obd2 connects but plug connector into distributor and instantly blows fuse. I will order new distributor tomorrow.

That's a new one on me. Glad you found the source of the problem.
