OK MY CIVIC WILL NOT START USUALLY AFTER RAINY DAYS. I HAVE NOTICED THAT MY FUEL PUMP DOES NOT PRIME WHEN THIS HAPPENS. I CHECKED FOR POWER AND HAD NONE, SO I WIRED IT DIRECTLY TO THE BATTERY AND THE FUEL PUMP RAN, BUT THE INJECTORS DIDNT OPEN. THEY OPENED ONCE THE CHECK ENGINE LIGHT TURNED OFF. I HAVE ALREADY REPLACED THE RELAY, AND THE WHOLE IGNITION SWITCH. WHAT CAN BE THE PROBLEM. ONCE I GET THE CAR TO START, IT WILL WORK THE WHOLE DAY WITH NO PROBLEMS????.. HEEEEEELLLPPPPPP

these cars are very bad for fried distributors, check your very carefully, mine had same problems.

My 89 Honda Crx HF won't start on rainy days-OK when it's not raining. I've changed the relay, still won't start. On dry days it starts fine. How do I go about checking the distributor for being "fried" as the other thread stated.

Thanks for the direction to the thread. Real helpful. Should be able to figure out the problem now.

OMFG, did I do something useful in that thread?

Something as simple as a cracked distributor cap can kill the engine when it gets damp.

When it will run correctly on a dry day, try misting a little water from a spray bottle on the cap and plug wires. When it stumbles you know you hit a problem area. Replace parts as necessary.
If you change out a distributor cap, be sure to replace the rubber seal part #13 here:

a huge list of items that could be checked in this case (that's what, 4 cases since last week asking absolutely same thing?) so yes, very useful
