Terrible day, car was running perfectly fine and then it wouldn't start anymore. Car has spark but no fuel, the fuel pump does whine and the main relay clicks, but the injectors won't spray. I swapped for a different ECU and the car starts, so I know it is my PR4 chipped ECU. Gives me a solid Engine light. The funny thing is sometimes it fires as well but the engine light stays solid regardless.
Now besides replacing Q31 Transistor and C14 Capacitor, what other components would you guys recommend? Too be honest all the caps look new and none are leaking. The transistor has a little bit of "browning" on it.
IC17 controls main relay function
Any advice would be helpful.
