Question about Honda Prelude
Engine turning normally but no spark at coil
If you are carburator or fuel injection you should have a tach meter hopefully it works. Crank the engine does the tach slighty move this small movement tell us if you have spark. You state no spark at coil 3 item that wont allow spark to happen the magnetic pick up the ignitor and the coil itself.Or even the distributor cap itself. 2 main failure for no spark is the ignitor itself. and the magnetic pick up

SOURCE: wont start
The problem is likely in the injection module which is located in the dash right behind the flip down tray to the right of the flip down fuse door the the left of the steering wheal.To test simply rapidly slap the fuse/vanity flip down door area while starting the car and it will start.I have had 5 preludes and all have the same problem a replacement is 150 or you can sotter all the connections on the board inside the fuel injection module.This will fix the problem as the original connections develop miniscule cracksAll preludes have this problem in really hot or cold weather

well if this is the model i think it is you have pgm ignition. you have an ignition coil , ignitor unit, ground wires all(corrosion) left to check.
after these things let me know if problem persists

There is a warm up valve on the throttle body(should have 2 small coolant hoses). remove the valve and have someone start the car while you block the port to the valve on the intake. If that clears up the problem you can cut a piece of cardboard to mount in between the valve and intake.should straighten it out.
