my 1990 civic dies at normal temp.

My 1990 Honda Civic DX 1.5, engine stops when it reaches normal
operating temprature. Replaced ignition coil and main relay and still
have the problem. Starts right up after cooling down for 1/2 hour or
so. It has a new distributer and plugs as well. Before I throw it in
the river, could it be the oxygen sensor or the fuel pump?

 

Failed oxygen sensors generally still allow a car to run. I
can't see a fuel pump being the culprit just because the car
has warmed up.

Because this is engine temperature specific, I would first
re-check the coil using the suggestions at
http://www.tegger.com/hondafaq/faq.html#startrun and the
free online manual at places like www.autozone.com .

 

if u figure out the problem with your car let me know Im having the same
problem
