Question about 1990 Honda Accord
My battery and altenator check out OK. When I try to start car on cold mornings I have to floor the accelorator. Do you think I have a fuel delivery problem?
I think you are missing the "cold start routine". The engine temperature sensor activates a computer circuit which changes the fuel mix and timing for the first few seconds to a minute or so on the startup.
Either it is failing to sense the engine is cold or the ECU is not using the info the temperature sensor is giving it. Go to a major autoparts store like Autozone and ask for the temperature sensor that controls the startup cycle. There may be a second sensor which just controls the dash gauge and you do not want that one if they are not one and the same.
I hope you find my soluiion useful. Please rate my info.

SOURCE: my car wont start
mine had the same problem but it would start in the cold but would stall if i tried to move the car.
once in a while i would get the check engine lite on would have a code that said burning too rich .
even when the light was not on it would go through alot more fuel than normal.
i tried changing all kinds of stuff o2 sensors, coolant temp sensor, throtle position sensor, air intake sensor, timing belt, and water pump just because its so expensive to change the timing belt and waterpump is run off of it.
compleate tune up roter cap to the plugs. and nothing worked.
the real problem that nobody but 1 mechanic knew just from the issues i told him.
lifter rockers too tight. and needed to be loosened and re torqued
it cost me just the price of 1 hour labor. about $90.00
he told me honda engins are the best but the lifters tighten up with time and must be re adjusted every 100k miles
mine had 120k when it started giving me cold weather problems and i only met the mechanic at 135k miles my second winter with the problem.
My CRV runs like a new car now!
Hope this information helps your problem..

SOURCE: car cranks just fine but
These cars have a problem with the main relay. They quit working when they get hot. This explains why your car will start when it is cold. Check out some of the other posts about this problem, also the Honda Civic.
