87 Honda Civic Si running problems

I have a 1987 Honda Civic SI with starting/running problems.
The acc. part of the ignition switch doesn't work and I think that relates to part of the cause. I try to start it and it starts but as I release pressure from the ign where the starter is actuated to the 'run' position of the ign sw. the engine dies.

You probably have a short in the ignition switch or a bad relay.

Anyone else have any ideas?
C'mon guys, I don't know all the answers.

yeah id say that u have a bad ign switch. but i do knw that there is a realy or two in the wire harness that do control that stuff but id try a ign switch first.

Checked it out and found that the ign sw is not working.......
Thanks!!!!1
