91 honda civic dx 1.5L quit running. Starts, runs for a few seconds just fine then stumble check engine light comes on then stalls. Started as an intermittent problem. Changed fuel filter, distributor cap and rotor. still won't run. has spark.
Try pounding on the gas tank with a rubber mallet or similar tool. (careful not to dent the tank) Try starting it. If it runs, replace the fuel pump (it's nfg). I've diagnosed numerous fuel pumps this way. Remember the pump needs to be replaced, if you drive it, you don't know when it'll fail for good. Hope this helps. Please post the results.

Update:
I have ruled out the fuel pump, fuel filter, spark plugs, distributor cap, rotor cap, ignition control module and catalytic converter. I can keep it running by revving the engine but it runs really rough.
