What could be the cause of a car starting up fine when it's cool. but after it heats up-it's harder to start or sometimes don't start at all?
My mechanic doesn't know what's wrong!! HELP!
it's a 2000 Honda Civic DX

The most common causes of this problem would be the coil packs which when breaking down work fine when cold but missfire when hot or under load. Another possible cause could be the camshaft or crankshaft position sensors as they also tend to breakdown whilst hot or under load.
Without further details on your car it would be difficult to go any further

This may be due to delay ignition timing, which is suitable for cool
starting. Correct the timing first. Secondly set the Valve tappet
clearance to recommended value.Correct the Fuel flow injectors
.Due to usage the spray nozzle holes
become wear out and inner diameter will be more. than normal
which can not be noticeable by normal mechanic unless
removed and checked.
The word mechanic means that he is well aware of all
essential working parts and components.
Normally all mechanic clean fuel system and spark plugs
when it comes for stalling of Engine and starting trouble.
Now during week end try to call your mechanic and attempt
to ratify the defects.

Sounds like the bushings in the starter are worn or the solenoid is going bad. When it's cool everything is a little bit smaller inside the starter thus less friction. When it's hot, everything is a little big bigger (heat causes expansion) and this creates more drag on the bushings. In extreme cases you can get a flat spot in the starter and it won't crank at all. Solenoids are affected by heat too. The older they get and the more times they cycle the more they are affected by the heat. Good luck!

Could be a few things.
Have your mechanic check the following:
Check the charging system. (If the charging drops, the car will run off the battery, drawing power, making it slower to start due to low voltage)
Check the ignition timing. (Incorrect timing can affect cooling, and starting. An overheated engine will start slower)
Check the cooling system. (same reason as timing)
Check the load on the starter. (A failing starter will turn slower, causing slow starts once it gets hot)
Good Luck.

There could be a number of things. The most obvious - first to check: clogged air filter element, incorrect temp sensor readings. Both will cause too rich mixture that causes flooding which makes hot starts problematic.

You find a different mechanic. Take it to a Honda dealership, may cost you a little more, but at least then can help you get fixed correctly.

Your mechanic is a dummy! Go see someone else. Is the car overheating? It could be your water pump.

Well when your Engines warm. Everything expands. You might wanna check your intake and Your cylinders could be clogged also, so check that out that might help

If your car cranks slower when it's warm, your starter or battery would be the most likely culprit.

Timing is off
