Sunday it would turn over but would not start. I had spark at all 4 plugs, sprayed starting fluid in the throat of the carburator. It would not 'catch'. I plan on checking the plugs next. I replaced the distributor cap and rotor button. I also replaced the secondary fuel filter even though there was gas in the old one and its hoses. I replaced the mechanical fuel pump 3 or so years ago. I used starting fluid and could not get the engine running
My 1987 Honda Civic will not start, Has spark, w starting fluid still no run on 1990 Honda Civic
Verify that the timing belt is not broken. Try cranking the engine over with the distributor cap off and see if the rotor spins. Or better yet remove the front timing belt cover and inspect.
Check the plugs to make sure they are not fouled, but maybe your timing belt has skipped a tooth and is now out of time. because if you have spark and it won't fire starting fluid its probably out of time
Try checking to see if your ignition coil has continuity and also check you ignition control module. They might still give spark, but just not enough to crank.
My car is doing the same thing did you ever figure out what was wrong with yours??
