87 lx-i help

[hnda2nv]

i have an 87 accord lx-i that intermitantly dies after it has been running for a few minutes. Sometimes it will run for up to 10 minutes before dying sometimes just a couple minutes. When it dies it is like i turned the key off, usually it starts right back up. i am hoping somebody has experienced this and might know the fix. Also when it dies something in the vacuum control box will click like crazy. please help!

It is the orange vacuum switch in the control box that is clicking. Also I have to cycle the before it will start. I ckecked for spark before cycling the key and there is spark. Fuel? Any help will be greatly appreciated.

What's clicking?

May take a look at the ignition switch, sounds like it might be failing.

[hnda2nv]

I can't really tell what is clicking in the box. I haven't been able to pin point it.

As for the ignition switch....that crossed my mind too. I know my 95 had that problem. But the symptoms weren't 100% the same. Of course neither are the cars.

thanks for help guys!

bump for update

Have you tried replacing the switch yet?

Have you tried replacing the switch yet?

No i haven't. Main reason is I checked to see if any power leaving the switch was pulsating and it wasn't also it looks like it has been recently replaced.

Have you taken the main fuel pump relay out, and inspect the solder on the bottom?

That I have done, I just went ahead and resoldered all of them just to be certain.

Can you take a picture of what is clicking in the vacuum box, or try replacing it. I don't know of anything that is suppose to click. Its possible you have a short in there, or a short going to it. It also sounds like you might have an issue with your fuel pump, but I would eliminate the clicking item first.

also noticed it only does it until it is completely warmed up then it runs just fine

In the shop manual that is the bypass control solenoid. It is part of the intake system that allows for low end TQ by opening and closing butterflies in the manifold. I don't think that is directly the problem tho, the opening and closing is determined by the ecu after receiving a signal from TDC/crank angle sensor. Sound like you may be having a problem with the TDC sensor, but that is just a guess. Download the shop manual and follow the procedures for trouble-shooting the bypass control system.

I definately will do it. Thank you sooo much!

Are you getting a check engine light on the dash?

[hnda2nv]

No check engine light. I have also been battling the typical fluctuating idle. I have found if I pinch vac hose number 21 (to map sensor) it smooths out. Maybe bad map sensor?

I can't make heads or tails of your pic and the issue has me flummoxed anyway. You might try to replace the clicking part with a junkyard replacement to see what happens.
