It's my wife's '93 Integra GS. Occasionally, while driving, it would just stop firing, but the problem was intermittent. Usually, it would start right back up. This time, it won't. When I turn the key, I can hear the starter going, but no catch to make the engine turn over.

The rotor was REALLY loose, so I replaced the cap & rotor. No luck. Now I've replaced the distributor. Still nothing.

Where should I go next? Solenoid? Would the fuel filter cause this kind of problem? No loss of power when it is running. HELP! I need suggestions!
