Honda accord starting problems
 

My son has a 1998 V6 Accord that has a strange starting problem.
Sometimes he tries to start the car and it will not start while in
park. Although, sometimes it will. He can turn the key to the on
position and pull the shifter into park and sometimes it will start
there. Sometimes it will not. When it rufuses to start he will move
the shifter back and forth betwenn neutral and park several times and
tries it again. Many times he will have to do this several times
before he can get the car to start. This doesn't happen all the time.
Sometimes the car will start with no problem at all.

I am assuming there is some sort of interlock microswitch somewhere
that is not being made all the time, and needs adjusting. I have a
Haynes book on the car. It shows a wire going from the starter cut
relay and the powertrain control module to the gear position switch
(through the neutral and park positions only) then onto ground. If
this is the problem, can someone tell me if this switch is? If not,
does anyone have any other suggestions at to what my problem is.

Thanks
