It used to be that occasionally my YJ wouldn't start when it had been running and engine warm. But its gotten bad now. Now it strats right up but dies after a minute. I have new fuel tank, fuel pump, fuel lines, CPS, cam shaft sensor, cap/rotor/plugs/wires and cleaned the Air idle sensor and throttle body. I have also tried swapping in a buddys YJ computer but Jp still dies after a minute. I have checked fuel pressure and press regulator and that's all fine. What else?
