1.8 GXE 125K MORNING STARTING PROBLEM.

2002 Nissan Sentra

Car would not start in the morning.

I sprayed some starting fuild and cank it for good 2 minutes than the car would start. Once the car is started it would run fine without a problem. ( And startes on first crank).
No code in the Car computer? Please help

Check the coolant temperature sensor and cold start injector time switch and cold start injector.

Cold start injector injects fuel for a short period of time-before the CTS takes over to demand fuel from the computer.

Check the CTS connection make sure its tight

Check the CTS resistances warm and cold-should have a high resistance when cold and decreases when hot. CTS should be close by the thermostat housing-not really familiar with this model.

The computer uses the CTS signal to determine how long to open the injectors for fuel demand during open loop mode -meaning when the engine is cold before the oxygen sensor takes over

Ckecked the CTS its fine. Where would I find cold start injector time switch? What would be the next thing to check.

Check the throttle position and airflow meter sensors connectors and bench test the AFM.
