Ok, I am a little lazy right now, and I was hoping this was going to be a regular thing with these HFs or cx's or whatever they are. I just cleaned the cap and rotor, threw some new NGKs in it, and the thing runs really nice. Its only got 35,000miles, those are original miles and is a 1990 civic.

What happens, is it takes a little bit longer than it should to start, turns over fine, but takes an extra second or so. Well, Today, we shut off the car went into a store, came back out 5minutes later, and it cranked but would not start first try, second try it fired and stumbled for a second than caught and ran fine. Same thing happened once more, I got home, shut it off, and started it again with that problem. It is intermittent however, but always takes a little longer than it should to start.

I have an idea of what it could be, but I want to see everyones opinions first. This is my fiance's car, and she is gonna kick my *** if I don't fix it today.

 

maybe its the main relay? electronics are more prone to failure due to time and the elements and not the # of miles on a car...

 

Another place to look would be the ECT sensor. When it starts to fail, it will send bogus signals to the ECU. Causing it to flood the engine on warm/hot starts. Might try un-plugging it the next time you try a hot start. If it starts up OK, that could be a sign it's failing and needs replaced.

 

Yeah, ok, you guys are on the same page I am than. On my old si, I had... now this may be the same thing your talking about with the main relay, but I had the fuel cutoff switch go... I think, but that was years ago now and I can't remember if it was the same problem. Tell me about this main relay.

 

BTW: 88_SC_CRX_SI the motor is not flooding (thanks for the idea though). I think the engine is not getting enough fuel on start up.

 

sounds like the main relay to me if it isn't getting enough fuel. do a spark test when the no start problem occurs.

 

cool, my link for the online crx manual doesn't work anymore.. and I lent my haynes to my fiances bro. You know where to find a wiring diagram online?

I think, we are talking about the same thing, is it behind the dash and a bitch to get to? Cause thats the thing I'm talking about. Thanks man.

 

yup i think we are on the same page here. try this link:

Thats sweet man, thanks much, I am sure thats the problem now.

 

I had a pleasant experience with the main relay/fuel pump just a few days ago.

When you have the key in the ignition in 'on' position you should hear the fuel pump start up while the check engine light is on for a couple seconds. You can also hold the main relay in your hand while turning the ignition to on and you will feel/hear it click to engage. Here is a more methodical way to inspect it:
