Good afternoon, can anyone familiar with CIS tell me where the fuel check valve is located? Does the system even use one?
Thanks Thomas |

Cold start issues:
1.) Cold start valve or thermotime switch faulty 2.) Fuel pump not running or incorrect fuel pressure** 3.) Air-Flow sensor plate rest position incorrect ** Problem could also be in the WUR for incorrect pressures. And if you have a 73.5 2.4L, remember that you have an additional control pressure regulator (WUR kinda) on the throttle body. |
