Change your ignition module. The distributor is a weak point of the Honda, I will always change out the whole thing than just try the coil.

could be a bad injector if it is still # 1 misfire.

Have you run a compression check on that cylinder? Have you verified the fuel injector is working?

check your compression, you might have low compression in that cylinder-also check your fuel injector in that cylinder, it may be damaged (wiring/connection) or defective.

If this doesn't do it, see my tip at http://www.fixya.com/cars/r5821173-doesnt_car_start_gasoline_engines . These are generic instructions. If you get stuck or need specific instructions for your car, please get back to me

#1 NEED TO VERIFY SPARK AT SPARK PLUGS # 2 CK FUEL PRESSURE AT SCHRADER VALVE ON FUEL RAIL ,,PRESSURE DEPENDS ON TYPE ENGINE ....IF NO SPARK AT SPARK PLUGS CHECK SPARK FROM COIL WIRE , IF NO SPARK AT COIL ,CHECK VOLTAGE TO IGNITION COIL SHOULD BE 12 VOLTS, IF NO VOLTAGE AT COIL ( KEY ON ) CHECK FUSES THEN IGHITION SWITCH. IF NO FUEL PRESSURE AND FUEL PUMP RUNS REPLACE PUMP .. CK VOLTAGE TO FUEL PUMP WHILE CRANKING . CK USING PUMP GROUND WIRE AT THE PUMP CONNECTOR THIS WILL PROVE GROUND ALSO. USE TEST LIGHT TO VERIFY

Go to Autozone or Oreillys and get a FREE scan. This scan will identify the cylinder that is misfiring. Your model may have a Crank and Cam sensor that is failing. These components replace Distributors in function.

A scanner should identify the problem.

Hi,
I love older cars. If they get gas and get fire, something occurs. I really would like more detail on what's happening with the car (symptoms)... but I'll throw a few bones out there.
If the engine is dying while driving, I would have to check out a few things...
Fuel issues, assuming the fuel pump is ok:
1. If it tends to die as you give it gas, it's possible the fuel filter is clogged enough to starve the carburator.
2. Is the carburator flooding out?... should be able to smell gas and it wouldn't want to crank readily.
3. Is there condensation in the carburator from "bad gas"? Get a fuel addative and pour it in your tank. It'll evaporate condensation build-up in the tank and carb as you run the engine.
Electronic issues:
1. If it runs great at all revolutions but suddenly dies, I would look at any loose wiring connections at the coil. Also check the hot wire to the coil and insure it isn't arcing on the engine due to burned off insulation.
2. Make sure your points/condensor are good and points gapped properly.
3. If it backfires out the carburator or exhaust when you give it gas, the timing is off a hair...
I may have missed a point or two, but these are pretty basic trouble spots. I hope we nailed it.
Cool car, by the way!
Hope this helped... Good luck!

replace crank sensor and if that isnt it replace #2 fuel injector
