First time post. I have a 01 xj. A few weeks ago I went to work and the check engine light came on. The code reader said that the cyclinder 6 injector was open. I did a tune up. New coil pack, plugs, injector and fuel rail. After replacing all of it still had a problem. I bought a 01 wiring harness because all of the injector wires were cracked. I just put in the wiring harness, Now it turns over and will barley fire and continues to crank. The code reader says the 3rd cylinder is now a circut open. I have tested all of the injectors and they are firing. The fuel rail has pressure. Has any one had this problem?
