1993 Honda accord will not start when warm. It will only start when its cold.

1993 honda accord 4 door sedan after starting and running until normal temp I can shut off 1 or 3 times until it won't start again. I have to wait until 45 minutes to an hour until it will restart then has same symptoms after it gets warm.
I have tried:
coil, module, cap, rotor, wires, plugs, fuel filter, fuel pump relay,
oms-ed out injector interrupter came out at 6.3 on all lines, checked all fuses, check battery and cables.
It is getting fire and fuel but still won’t start until its cooled down again.

 

If it is getting spark and fuel then make sure its getting air and also check for compression. First try to spray starting fluid in the throttle body if it starts then it isnt getting fuel.

 

i had the same problem a while back. i will just use starting fluid to get it started on hot days. found out the problem later. it was the fuel pump relay. hope this help out.

 

First determine what's missing from the equation: Spark, Fuel, Compression. If you're not getting fire look into your ICM (ignition control module) or the Ignition Coil. If you're not getting fuel turn the ignition switch to the "on" position and make sure you hear 2 clicks from the main relay. 1 click as soon as you turn the switch on and 2nd click 2 seconds after the switch is turned on. This indicates that the fuel pump is being enegized to pressurize the fuel rail in preperation for starting the vehicle. Let me know if you need any more info about these instructions.

 

sounds like a main relay. I don't know if that's what you mean by fuel pump relay. I had the same problem too just rest replaced my main relay. I have found out that the cheapest place to get them is O'Reilly Auto Parts. I hope that helps

 

^^ x2!

 

i had an accord back in the day that you would have to turn the key a few times to "prime" the system. found out that the fuel strainer was like a brick. changed that and it ran like a demon.


also, had a friend with a del-sol. it would start when cold only to shut off after getting to normal opperating temps. it was the (dont know what to call it) black box inside the distributor...... it had a hairline crack and would expand just enough when it started to get hot

Again, determine what's missing. It's easy to start guessing what parts to throw at it. If you know what's missing (spark, fuel, compression) then you will save time and money. Sure there are common pattern failures on these cars, but try and diagnose properly. That's what distinguishes the good techs from the lazy. @bzmotoninja1983: I believe you're thinking of the ignition coil. He says he replaced the coil. I would look deeper into either the ICM or Main Relay. I can give you detailed ways to check either of them.

 

Justinsbg, I don't think it was the coil. But, who am I to say what's what in a Honda? I'm just a redneck with a 4x4....lol. @OP, I agree with Justin, tossing part at it then freaking out because you have checked "everywhere" just means you missed one small detail. Good luck
