92 Honda Accord will not start when temp outside is below 50 - HELP!

[TS20]

My 1992 (manual transmission)Accord will not start when it is below 50 degrees outside; it will turn over but not start and I can hear the fuel pump start when I turn the key so that is all good...I have just replaced the Main relay and that isn't the problem, I also replaced the water pump and timing belt not too long ago and they should be fine...I really need to find out the problem with my car and I have a strict budget so any help/advice would be much appreciated!

On a different note, I also had the a/c compressor lock up on me last year and any advice on that would be great too...but my main concern is the not starting in the colder weather.

My guess would be the ignition switch is going bad.

I got some good advice here last week on my 89 Accord that had a hard time starting in cool weather. I was told to check the resistance of the water temperature sensor. Maybe you have the same problem?

Refer to the Owner's manual, and try the suggested fixes for COLD starting, then try the fix for FLOODED engine. It sounds like you might have a dripping injector . . . Is it worse if it sits all weekend?

This would be my guess as well (not the ignition switch, that typically has different symptoms!)

The so called TW sensor tells the ECU the coolant temp. If it fails and indicates a warmed up engine, you will have enormous difficulty starting it. It's a cheap part, and it is pretty likely your problem.

If you need to start the car, or want to verify that this is the problem, use started fluid in to the intake snorkel while someone cranks the car (don't touch the gas pedal, just crank normally). Once it catches, use the accelerator pedal to hold the engine speed at 1800-2000 rpm. It's possible you'll have to restart a few times this way, but after about 20s of running you will be able to keep it running with the accelerator pedal. This will rule out the ignition system or an air blockage etc.

Good luck,
