So I bought my first ef to use a a daily driver while I work on my gsr but anyway problem just started when the weather got wet and colder I live i'n Washington so I go out to start it i'n the morning and it won't start if I wait till till later i'n the day(after it gets warmer and dryer) it stars right up. Weird huh maybe bad dizzy? Getting moisture i'n it? I don't know what to check first? Any and all help would be appreciated thanks for looking please help!!!

 

P.s it's a 91 dx with dual point.

 

main relay is common on an old civic like that

 

Would the main relay really only cause it to do this is the mornings cuz any time after i would say 12-1 it's starts right up no problem

 

Could it be the cold start injector? That's what I'm gonna change when i get off work!?

 

I live in Tacoma but i'm mpfi in the morning it's always a hard start but if I crank it for what seems like 5 minutes really like 30 seconds it starts and main relay would cause the opposite not starting when it's warm out also check spark plugs

 

The other common part to fail with start issues is the ignition ignitor

 

I can almost guarantee you it's the Main Relay. About $50 from Honda and worth every penny.

 

Usually it's the heat that causes the solder cracks to expand, not the other way around.

 

Update. So I changed cap rotor and plugs Now it has a bad miss.!?

 

Your firing order is wrong those things wouldn't cause that unless the screw came out of the rotor lol that happened to me I didn't figure it out for like a days and half and some searching on google lol but if you crank it long enough it will start

 

hallo allemaal .. im nieuw op dit Foum .. bedankt voor dit bericht echt geweldig ...

 

yea, but this is the same symptom I have experienced several times and have fixed by replacing the MR.

 

Ok so it started right up this morning but still has a real bad miss when I'm trying to excelerate. I'm thinking it's the junk auto lite spark plugs my girl got me I went to gap them at .040 and the were already gaped at some where over .046. What do you think I know ngk says gap there's at .044 but these aren't ngk. Autolite junk pre gaped.? I think I'm gonna put the old ones back i'n start there and see what happens

 

On yea and I'm getting 15 short flashes.!? I heard that it's not even a valid code?

 

Ok disconnected the battery for 10sec to reset it and now no flashes as soon as I get a chance i will go drive it. I'm at work haha.

 

Ok just drove it. Runs better but still a slight miss/ hesitation so I went to adjust timing again and stripped the dang bolt so I will have to do this after work when I get home I'll keep you posted.

 

Most plugs nowadays come pre-gapped at the correct gap for that type of plug. Usually a main relay problem can be kinda random as well. If it starts up fine sometimes then doesn't start other times regardless of time of day, you'll know for sure. You can also listen for the MR click when you turn the key.

What kind of gas have you been running in it? Perhaps running a higher octane for a couple weeks to try and help clean stuff up a bit would help?
