    Engine Dies

    Thanks for the help. The mech. that checked the car used his scan tool and all pressures and temperatures checked OK. You would think that the problem would arise shortly after the car is shut down as things heat up a little before they start cooling off. But the problem occurs after the engines has cooled down for 20 minutes. If the engine acts up after the 20 minute interval then it takes another 15 to 20 minutes before it will start. Turns over fine, just will not start. Once the engine starts, it runs like there are no problems at all. I think you could drive the car cross-country as long as you did not turn it off for the for these short periods of time?

    Mick24, Edited the original post and added some stuff. Also changed the igniter today, as in the post, the engine started fine and ran good, really smooth. Let it warm up good then shut it off. Restarted it about 15 minutes later. It started OK the the engine started surging speeding up to around 1500 to 1800 RPM, finally it settled down then started stumbling then it die. I was 15 minutes before it finally started again. The guy that checked everything when this first started happening is a Toyota mech. he used a scan tool and no codes were present the only thing was that fuel injector pressure was high because they were dirty, the system sensed the engine was running lean so it increased fuel. He cleaned the injectors and the fuel pressure went back to normal. You can drive the car on the highway and everything seems great? Thanks for your help (I am lost)

    We have a 1996 Toyota Camry 4 Cylinder. After the car is driven and the engine warms up, when you stop and turn off the engine, for like running into the store for just a couple of minutes everything seems to work. If you shut the engine off and wait 15 to 20 minutes then try to start the engine, it may start or the engine will turn over but will not start, or it will start then stumble and quit. From that point if you wait about 20 minutes, then the engine will start. The ignition system is firing, there is spark at the plugs, it seems like there is no fuel, but sometimes you can smell fuel? Also as the engine is warming up, it may speed up to about 1500 to 1800 RPM, the engine will run at this speed for a couple of minutes then slow back down to an idle. This also happens when idling at a stop light etc. Some times the engine will stumble, if this happens and the engine dies, it will not restart for about 20 minutes. If the car is at an intersection, parking lot etc. you are stuck till it decides it is time to start. . We have had the ECM scanned, no codes show. The only thing the scanner showed was dirty injectors, we had the injectors cleaned by a Toyota mechanic, he also suggested we do a secondary ignition tune-up, so we replaced the plug wires, spark plugs, distributor cap and rotor. The engine runs better and does not seem to be any problem as far as highway driving goes. The problem only occurs at idle or after the engines has been shut down for a little while. The car has 90,000 miles on it. A friend said to try changing the Distributor, Igniter, ECM in that order, lots of money any way you look at it. I changed the igniter today, the engine ran smooth as glass, warmed it up good, then turned the engine off and restarted it about 15 minutes later. It started ok but then the engine started revving up then back down by it self, then it stumbled and quit. Would not start for 15 minutes. Any IDEAS, Thanks
