Crank spark and fuel, but no start?

Hello, are you sure you're getting a really good strong spark? How are you testing spark? Does the Check Engine light come on for a few seconds while cranking?

A few things you can try are to hold the gas pedal to the floor and crank the engine over, see if the engine has a nice equal sound while cranking. If you hear any type of, drop out or odd sound while cranking during this test it could be an issue with the timing belt. If you can't even get it to start with starting fluid and you have a really strong spark, I would check for fuel injector pulse just to see if it's happening at all.

Also when you crank the engine over with the pedal to the floor, it should set the car in Clear Flood mode, where it won't fire the fuel injectors, this is a mode where if the car is flooded out, this will clear out the cylinders of any gas that might be hindering the spark plugs, but it is also a good way to get a sense of any compression issues. It should have a very nice, even rhythmic sound and not be cranking over extremely fast as it would if there was a broken timing belt.

Another possibility is the Catalytic Converter is clogged up. Do the spark plugs look like they are black and covered in soot? Checking the spark plugs can give you an idea of what the fuel system is doing.

If you suspect a Catalytic Converter (Cat) failure, you can either drop the front of the exhaust before Cat and try to start it or pull out the front Oxygen sensor and try to start it. This will allow the back pressure to escape through the oxygen sensor hole.
Here are some guides to help. Let us know what you find.

There is a Recall on the Ignition Switch Interlock defect. This may be contributing to this starting issue, if there is a voltage issue happening with the Ign Switch. Just wanted to post this. Try starting it in Neutral with your foot on the brake pedal.

Hello, I assume you are responding to our previous posts. Were the spark plugs wet smelling like gas? And that voltage reading to the Distributor is low. I would check with the negative lead on the battery negative, it sounds like the engine is flooded out if the spark plugs are wet. Try cranking the engine over with the gas pedal pushed all the way to the floor. See if starts. If not, the ignition coil could be weak. the ignition coil igniter could be going bad. Hondas are known for their Ignition system failures. There are pick up coils inside the Distributor that are used as a crank and cam sensor for cylinder reference. But the spark plugs being wet is the clue because it's not starting. It might be time for a tune up, spark plugs, wires, distributor cap, fuel and air filter. I'm not sure when this was done last, but the mileage is high enough. You can respond here; the email is just to notify you that I have responded to your last post on here. But see what's on the spark plugs. Fuel fouled or does it smell sweet like coolant?
