My mechanic a thirty honda crtified mechanic has checked spark plugs, timing belt, ignitor coil, distributor, fuel pump, main relay,injectors, noid getting signal from PCM... WE ARE STUMPED!!

If the Check Engine Light comes on and then goes out after 2 seconds, when the ignition switch is turned to ON (Position II), then focus on the distributor. Normally, replacing the Ignition Control Module (ICM) and coil inside the distributor solves the problem. If the problem persists, install the new ICM and coil (aftermarket are fine, to keep the cost down) in a genuine Honda distributor housing--all other distributor housings are junk and unreliable.
