every morning my car turns on like a champ...but more and more offten it is having a hard time starting, if i turn it off for only like 10 min.

if the car hasn't cooled down, it wont turn on. it will just turn and turn.

now i park on slopes so that i can just roll start my car when it does this. that sucks. what do you guys suggest this can be.

 

any help is gratly appreciated.

 

What year Civic?

When the engine won't start, have you noticed whether the fuel pump fails to prime? Is there bright bluish spark at each of the plugs?

Edit: Roll starting works even though the starter is cranking the engine fine? This could mean a problem with the ON(III) position of the ignition switch.

well the fuel pump primes pretty loudly, and never fails. haven't had a chance to check for that spark tho. what would it mean if no bright spark.

oh maybe the ignition switch? but how tho. why is it only an issue when warm?

 

If spark is weak (orangish color), it won't be hot enough to ignite the fuel. This is generally caused by a bad coil.

Given that you can roll start the engine in ON(II) but not start it in ON(III), the IG1 terminal of the ignition switch in the ON(III) position but not the ON(II) position may fail to make good electrical contact after the switch has warmed a bit, possibly due to current flow through the circuit. The IG1 terminal provides power for both fuel and spark.

 

funny. cause yeah.
my i messed up my switch in a way that it would always beep as if it had the key in it all the time when the door was openned. so i just unplugged the door pin. but damn you good. that might be it. but i'm sceptic tho.
