doesnt mean its the computer system--that cud be an egr valve-dirty throttle body or idle motor------ignition components like ol plug wires or failin fuel pump------even vaccuum leaks
take pipe of carb turn over see if fuel comong out,if not check fuel filter ,check plugs for spark,no spark check points on distributor. fuel/spark ok check timeing.if fuel/sprk/timeing ok check carb/jets for dirt ect;
CHANGE AIR FILTER AND FUEL FILTER THEN CLEAN FUEL INJECTORS,CHECK SPARK PLUGS SEE IFTHEY ARE BLACK SOOT ON THEM.MORE LIKELY SPARK PLUGS GETTIN FOULED OUT DUE TO CLOGGED LEAKING FUEL INJECTORS.CLEAN FUEL INJECTORS.POUR BOTTLE OF SEAFOAM TO 3/4 TO FULL TANK OF GAS
COULD BE STOPPED UP FUEL FILTER.CHECK FUEL PRESSURE SHOULD BE 48 PSI. IF LOWER HONDA ADVISE TO REPLACE FUEL FILTER.YOU HAVE TO REMOVE FUEL PUMP THROUGH ACCESS PANEL FROM THE FLOOR.IF FUEL PRESSURE OKAY.REPLACE AIR FILTER.REPLACE SPARK PLUGS IF YOU HAVE OVER 110000 MILES ON THEM.IF SPARK PLUGS BEEN CHANGED ALREADY.IF ENGINE STILL WONT CRANK AND IDLE.CODE SCAN FOR A FAULTY IDLE AIR CONTROL VALVE.
This would include your spark plugs or coils, the wires, a new distributor cap, an oil change, air filter, fuel filter, and a coolant flush. A tune up can make a car run like new again. Some don't change the fuel filter on a tune up but I have always said it is best too. They can get clogged up over time.
With a new plug and fresh gas it should start. Check to make sure there isn't a kill switch turned off or that the gas petcock from the tank to the carb is on.
How did you check the fuel filter? Disconnecting it from the fuel line that goes to the carb is the best way, making sure the gas is turned on under the tank. Bleed off a little gas into a can or something just to make sure the filter isn't plugged.
The last thing I'd do is take off the air filter and spray a little starting fluid in the carb. It may start and run several times if there is old gas in there somewhere. Remember the bowl on the carb is probably still full of old gas. After some fresh fuel reaches the plug it should start and continue to run.
(You might drain the bowl on the carb of ols gas before you go any further)
Not terribly familliar with honda cars but most systems use either a cold start injector or just richen up mixture through the normal fuel system. This is controlled by a temperature sensor, either separate from or part of dash gauge sensor. I'd begin looking for that. If its always in "cold start" if will give you symptoms like yours. If not fuel injected, check choke operation. This may not be a "cure" but it's a good place to begin looking!
What problem?
