I have a 1989 Civic DX Hatchback. I have had it for a couple of months and it has treated me perfect since I got it. About 2 weeks ago, maybe 3, can't remember I was trying to start it after I just stopped off at a convenience store and it wouldn't start. I had to wait a couple of minutes before it would start. So it has done this a couple times and I have determined it won't do a hot start. For some reason the motor has to have been off for a time period before it will start again. I can't figure out what this time period is as it seems to change. It turns over, but it just won't start. I have checked the plugs, they are clean, and the distributer cap is in good condition. I asked my autos teacher about it and he said he would really need to look at it to figure out the problem. So I was wondering if any of you have had any experience with this problem and what it could be. Thanks a bunch.

 

again on my s10 i had this problem. check your fuel pump. ill almost gaurentee it.

 

So the fuel pump just overheats? How much would a decent fuel pump cost on my car? If I don't fix it right away I assuem it will just stop working?

 

your problem isnt the fuel pump, its the main fuse relay..

search on here its been cover 10000 times and im positive thast ur problem, fuel pumps dont go out much on Ef's

 

no its just going out like parts that are 15 years old do. or check your main fuse relay. i was just talkin about my past expeirience and the fuel pump will probably be like 30 bucks.

 

Just resolder the contacts. Did this to mine too. haven't had a problem in two years.

BUMP

 

its the main relay. no need for bump

 

As others mentioned, this sounds like a main relay problem.

 

anyone else for the main relay theory

 

When my car had this problem,
I thought it was the fuel pump so I replaced it
with a brand new one..$$$ expensive it was...

So then it did the same thing as before the first time I drove it...

I then replaced the main relay and have not had a problem since.
That was over four years ago..

I hope I don't sound like an idiot for asking this... But in my experience with cars, I have never needed to work on a main fuse relay? What is it and where is it at? Is it just something that is ran to the fuse box or whatever? Also... Now that I know what the problem is I would also like to know why. That way I can better understand the problem. I think it is better to fix something, and know what and why you are fixing it, instead of just doing it. So yeah. Thanks for the help.

 

It is called a "Main Relay"..

If you will click the second link I posted,
it will show you what it looks like and the location..

 

Where is it?

 

Ooops Sorry. I didn't see that second part. Ok, thanks a bunch.

 

FYI: 99% of the time the relay is the problem. The next most common thing is the distributor, then you can go down the laundry list of other possibilities. I re-soldered my connections in the relay but still was having the problem (although less often) so I just got a new one at the dealership. Less than $50 shipped to me. I would just drop the money for the new one.

 

if you get to replacing the fuel pump,get a 255lph walboro,bbk.etc and get something in there that will support the mods that you will want to do. i got mine for $70 brand new installation-free courtesy of myself. just do it!
