I have 1987 Honda Prelude 2.0 Si (Fuel Injection). It is running great.
I am having a unsual problem during start up for the past 3 weeks. I
start the car in the morning, it starts without any problem. When I
start the car during afternoons or evening, sometimes the car does not
start. It cranks and dies immediatly. Then, I have to wait for 2
minutes and then start again, the car starts! If it does not start, I
have to wait for another two minutes and then start. Note that I get
this problem mostly when the whether is hot. During rainy or cold days,
I don't get this problem. When the car has trouble in starting,
sometimes I start by holding the accelerator pedal all the way
down...and it works sometimes and the car starts...sometimes it doesn't
work. Once I start the car, I don't have any problem during driving.
Runs smooth. This starting problem is because of some electrical issue?
Another thing I noticed is that my horn is not honking...it honks very
very low for a second or two. Does this horn and staring have some
connection? I took it to mechanic and he is not able to find out the
problem. He told me to tune the engine and I did that (change fuel
filter, air filter, clean battery, change the connections, change rotor
cup, checked radiator coolent level,...). After that, I did not have
problem for a week...then, it started again. Then the mechanic changed
the ignition coil. But, I still have problem...he is suggesting to
change distributor. But, he is not sure whether it will fix the
problem. So, I decided not to do that...any of you had similar
condition/experience before? Any idea what's going on... Please tell me
what could be wrong... man, I love this car, it is very reliable and
gas efficient...please help. Thanks a lot.
