Today at a light someone collided with the front of my 1988 Z31 at very low speeds, after checking damage and seeing that the only damage was one of my lights being pushed inwards (5 second fix) we both left. Car started up just fine but after 5 minutes it suddenly lost all power and I had the push it into a parking lot. After popping the hood there was now a thin tube connected to the engine leaking gasoline from a rip, I cut the tube down past the damage and reconnected it. It now fully turned over but would continue to lose power after driving for around a minute. Got it home as I was only 2 minutes away and checked my ECU and it was giving code 22. I checked the fuel pump relay but it is fully working. Now I'm just not sure what the next thing I should be checking is.
