I have a stock 91 240sx ka24de. At first it had no fuel, had a bad relay. Now it has too much fuel, to the point of hydro lock. Cylinder 1 misfire, all 4 plugs and wires are firing, fuel is getting to all cylinders. Compression is 153 cold test across all 4. Swapped out know good ecu, harness, dizzy, and injectors. I unplugged all 4 injectors removed fuel feed and return line off the motor, pulled fuel pump relay. The car still start and runs, won’t rev high due to super lean. But it starts and idles with NO FUEL getting to the motor. While it was running with the fuel disconnected I plugged it all back in, car died from too much fuel. I was a tech at Nissan for 6 1/2 years Never seen anything like this.
