I changed the temperature sensor and cold start valve. I even checked the cold start valve before installing by connecting the fuel line and apply 12 volts, with ignition on and it sprayed fuel.

After installing it, the cold start valve does not get 10-12 volts when cranking the engine. Could be the MAS is faulty? What else besides temperature sensor, cold start valve and MAS is involved? OVP fuse is fine.

When I apply 12 volts to the cold start valve, the engine starts ok.

Any help would be appreciated.
