car won't start after stalling or under sun for long time

[BootlegCB7]

I have a 91 accord ex, sometimes it will crank but won't start if it seat under the sun for like couple hours or right after stalling it.

I thought it could have been main relay heating, so I have removed cruise control box and drill holes on the relay box. The relay didn't seem to have crack or burned.

I have replaced plug, wire, cap, rotor, and the coil recently. so I'm guessing it is either the fuel problem or some electrical gremlin hiding somewhere.

Need ideas on where the problem is, I will thank you in advance

drilling holes wont fix the relay

could be the ignitor.

Just to clear somethings up, the car runs fine and it is in running condition. Just that when it seats under the sun or stalls, for like 5 minutes i get only crank no start. <_<

You need to actually FIX the main relay. Drilling holes in it only prevents it from going bad again. Get that thing out and resolder it. You won't be able to see the cracks in the solder unless you use a good magnifying glass.

If you did not resolder it then the relay is still bad. The cracks on the contacts are very hard to see. Resolder or replace with a new one and you should be fine.

lol, you can't just drill holes in the case. Thats like cleaning your engine w/ a rag to get the dust off, when really it needs an oil change.

Just get back in there and take the case OFF the relay. Then what I would do is resolder ALL the points, even if some look good, they may fail really soon in the near future, so its good to do it now before it leaves you stranded or something.

Replace or repair the main relay (as stated above, you need to redo the solder points, and you need magnification to see where they're bad). Replace the igniter. Replace the ignition coil.

Those are the 3 main culprits for a no start or stall in the heat.

the same thing is happening to me just now car won't start i open the hood and check for spark on the wire there was none i have a 92 LX and i have external coil i chek that is working but from ditributor theres none, also the fuel pump is not priming and i went to work this morning just fine car sits under the sun for a while and bang!! wont star.....i dont know what to do!

Main relay, to start with. Fix it or replace it.

^^^ what they said. I've fixed two b4 and I just resoldered all the points in it, just to be sure. They've both worked flawlessly since.
