It is hard to start when cold. My in laws mechanic tried to clean the idle control valve. Did not work
I switched the cold start valve with a known working one and no gas is sprayed from the valve.
There is pressuer to the valve, how can i make the valve open manually?
I can put a cap full of gas into the intake and it will start right away. Once hot there are no issues.
The trouble shooting suggests changing the thero-time switch. Where is that? How can I test it?
Changed the plugs, wires look good I still have to check the cap and rotor.
Does the car have a obd2 connection to check for error codes?

Also the EHA is leaking, should I replace it or just change the o-rings?

thanks for the help in advance.
Have to be careful of all the plastic and rubber parts there are very dry and can break easily.

The cold-start injector only fires when the temp is below 60F or so.
So, be sure it's cool enough for the computer to turn it on before condemming it. To make it fire manually, just unplug the connector and hit it with 12V. Poor initial start above 60F can be traced to several things, but injectors are always the first suspect. If you turn the key on for a few seconds, then off 3 times before starting, and it improves, check for retained system pressure, the accumulator or check valve leaking, or a clogged filter (unlikely).

edmatu, from my experience a crack in the EHA black plastic causes leaking gas so the EHA needs to be replaced. Recommend removing the air filter assembly when the engine is cold, then start the engine and closely inspect the EHA for leaking/weeping gas. You would be fortunate if new "green" O-rings resolved your leaking problem.

This the results after turning the key on and off 4 times, it still takes about 10 attempts to start and stay running. it will idle very slowly and if you press the accelerator it will stall.
I will change the gas filter and once I get the gaskets remove and clean the ejectors and replace the EHA O-rings. If I still have a issue I will change the accumulator. I will post the results once completed.
Thanks for the help.

Update
T replaced the EHA and the leak is no longer a issue, but I still have a problem starting.
I checked the thermal time switch and there is a low ohms reading, and it stays the same when the car is warming up. the cold start valve is never getting any power to help start. OAT 40 degrees. I but power to the cold start valve manually while starting the car cold and the car started while tapping power to the valve. once the car is a normal temps it will run ok. anyone know the part number for the thermal time switch, its a 4 prong censor.

Thanks
