Jun 28, 2010 - Car starts and after warmed up.. it dies! ... but if i let it sits for awhile till the engine is cool down it starts right up but after its warmed up.. it dies.
Replace the temperature sending unit/sensor. This sensor tells the computer to put the engine into cold start mode and it then sets idle a bit higher and puts a bit more fuel into the engine to keep it running without having to touch the throttle. Once it's warm, sensor tells computer to go to normal run mode and it's done. No problem.
Ok, time for car school. The vehicle is operated by the computer, every electrical concept that is. When the engine is cold, it starts fine because the computer has placed it in "cold start mode", putting more fuel into the engine than normally would until Once the engine is warmed up, a temperature sending unit or temp sensor tells the computer to change to normal run mode. IF said temp sensor is faulty and is not telling the computer to make said change, it stays in cold start mode, still dumping excess fuel in the engine that is now not required, cause it's warmed up. Like keeping the choke closed on older vehicles. Now I think you can answer your own question, when this no start action is happening after warm up and it always starts fine when cold, what's the first thing you check ? Right, the unsuspected temp sensor. Change that and no more start problem. Have a wonderful day. Glad I could be of service.
