Q: Why does this Toyota not start sometimes when it's warm. on 1994 Toyota Corolla

Rookie cbe0621eac06868b3efe0d8d1d3611e23c60d3114864ea2ec19a68cfbd3eebab
It cranks but won't start sometimes. I have checked the timing and it's fine. I replaced the distributor and a weak relay. All components are functioning as they should, and when the car is cold it starts fine but when it gets warmed up SOMETIMES it won't start. After it sits and cools off it will start again. It runs fine when it does start.

No it has no spark to the plugs when it won't start and no to the engine light being on.
yes, complete new distributor. I've been trying to locate this problem on this baby for a couple of weeks now.
Heat is breaking down an electrical componet somewhere but that is a no brainer. Usually the distributor will fix this problem! Hard to cure an intermittent!!!!
I aint hit a lick today PG! We are a little slow right now anyway, always have been this time of year and when hunting season starts. I just work about 20 hrs a week to help an old pal out. Got some young bucks working for him and you know how that can be! They good wrench turners just dont have the natural talent and dont want it either! Cant teach this stuff, got to have it in the blood!! I really do believe that!

Can you direct me to where the open circuit relay is located on the 1994 Toyota Corolla??
Thanks, I shall check it out tomorrow. Finally found the open circuit relay located directly under the center of the dash/heater levers, behind/under the console. I was guaranteed from another mechanic that had to chase down the same problem that...replacing this relay would solve the random no start problem, hope he was correct.

Thanks for your help and Happy New Year.
Check that you have voltage coming from the Coil.
I just had a similar issue, where it would start but as soon as the engine warmed up it would cut out, and then not start again until it cooled down
this was due to a worn out coil.
