Engine Starting Problem

I need some help diagnosing a starting problem w/ my 88 DX Hatch. Sometimes when I go on a short drive like 5-10 miles and shut off the car and go shopping lets say for like 5 min. when I come back out to the car it won't start.:rolleyes: It will turn over just fine but it won't start. If I wait like 5 more minutes then it will fire right up. :confused: FYI I am getting a code 1 but I'm pretty sure that's just a bad O2 sensor. Any help would be great!

I had a similar problem. It started out like u said, when i tried startin the car after it had been off for 5 min it wouldnt start, but if i waited it'd be fine. Then the problem changed, i eventually couldnt start it at all when it was hot out (aka: daytime) but it would start fine at night when it was cool. Long story short (not really), the problem i think u have is the main relay. U can either buy a new upgraded one, or do wat i did, take it out, open it up and resolder all the joints together. The directions
here (http://www.crxsi.com/resources/repair/fixing_main_relay/) should tell u pretty much everything u need to know. Of course, it may not be ur main relay, but i'm 90% sure thats the problem. Good Luck!

Thanks for the help but one more question, you mentioned the upgraded one I can buy, how is it upgraded and where can I buy one?

I have a 89' Civic SI with probably the same problem.....would this apply to the SI also......also would be interested in the upgraded part....tks/greg

Try your local honda dealer, or just open it up and solder the one you have.Resoldered should work for quite awhile, look how long the first one lasted......

how is it upgraded and where can I buy one?

Its "upgraded" just because they made a better one, one that wont get the same problem as the one u have now, not quite sure how that is, but i believe em. There pretty cheap too, i think only $40 from a Honda Dealer, it would probably be a lot less hassle than resoldering, which i wouldnt reccomend doin if u dont have practice with it (u car fry the hold relay if u screw up!). Anyways, thats how its better, good luck. :frog:
