I have a 1991 Honda Accord that when I try to start it, it only runs for about 1 to 2 seconds and then stops. It continues to do this I try to start it. My wife was driving and stopped at Micky D's and when she came out it wouldn't start. She indicated that there was no problems before she stopped. General info: 190,000 miles with standard transmission. New coil, new igniter module, new fuel relay under the dash, new plugs, new wires, new fuel filter (about one month). Checked fuel flow after the filter and have good flow when ignition on. As I'm trying to start it I get spark at the plugs when the starter is engaged but I lose spark when I release the starter. Could it be the ignition switch or some fuse or relay? I think I have tried all of the usual culprits.

Replace the ignition switch:

You've done a lot of good things to your Accord.
