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.
What is a good method to ckeck these items?
Thanks for your help.
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.
Thanks
Change the CTS but still have to crank a lot in the morning, ones warm up no problem? What next in line to check.
thanks
Check the throttle position and airflow meter sensors connectors and bench test the AFM.
