1990 Honda Accord won't start when engine is warm

My honda starts just fine when the engine is cold, but after it warms up,
it won,t re-start. It acts like the engine is flooding. Any ideas?

 

Two words: Main relay!

 

So what happens?

Does it fire then die right away when you let go of the key?

Does it crank and crank and crank but not "catch"?

Does it seems to "catch" momentarily but then fail to stay alive even
though you keep cranking?

Your primary cuplrits right now are the Main Relay and the ignition switch.

 

that's correct. Since I bought another main relay, I got no problem
with it.

 

I replaced the main relay and the map sensor, but it did not solve the
problem. When the engine is warm and i try to start it, the egine acts
like it wants to fire when I first turn the key, but then just spins. Any
other ideas?

 

Ignition switch? Have you tried a new key?

 

Try cleaning the distributor cap inside and out. If that fixes it either
wash it and polish it or replace it.

There's an article on my website (below) in the 'Miscellanea' section
which is similar to your problem. Although it is 'Rover' the engine is
Honda!

 

Hi,

After trying the same fixes as you with my car it turned out to be the
ignition coil. After my honda dealer placed a tester off his bench in it my
car has ran perfect ever since.

Your shop should be able to try the same thing.

Cheers,

well,after procrastinating all this time, I pulled the ignition module from
the distributer and it tested bad at the parts store. After replacement,
the car is running fine again. Everyboby, thanks for your ideas.
