1994 Camry will not start cold and dies when warm

[redrider39]

Help! I am working on my daughters 1994 Camry CA 2.2L 4cyl Automatic

It won’t start in the mourning even though it turns over fine and has spark.
It will start in the afternoon after turning over a few times.
Once started it runs good for about a half hour than it starts idling erratically and dies at stops.
I have cleaned the throttle body, changed the coolant temp sensor, the TPS, the Idle Air Control Valve, and disconnected the EGR valve.
I tested the Air Intake Temp Sensor and ohmed out the engine wiring harness from the sensors to the ECM all checked out good.
Any new ideas would be greatly appreciated.

Thanks.

does this engine have a cold start valve? the extra fuel injector that sprays some extra fuel in when cold)

Hi
No cold start injector on this one. I wish there was it might help.
Thanks for the reply.

Just a hunch here, but check out the coil. They have been known to cause sporadic problems, including some no start problems. You have done all the other logical things already. You will need your DVM or multimeter and the specs from any manual to do this. Also, inspect the coil carefully for hairline cracks.

Good idea I did pull the cap and the coil looked new but I did not check it with a DVM yet.

Thanks

Here's an update. Problem solved! The Camry had a weak ignition coil. When cold the resistance across the primary side of the coil was 100 ohms. I also changed the plug wires they all had high resistance. The Camry now starts and runs like new!
A big thank you to the people who replied. You gave me a much needed jump start to the brain cells. I was getting frustrated with this car and wasn’t thinking clearly any more.
