Gentlemen,
A friend of mine has a geo with the suzuki engine in it. I am unsure of the year model. He is having problems with the engine not starting while hot. When the engine is cold it will start and run ok. He has an extra junked car so he starte swapping out sensors. He has swapped out all sensors on the engine and the ecu, with no luck. In hot start the engine appears to be getting fire to plugs. So injectors must not be getting pulse. If you give the engine a slight shot of eather in this condition it will fire and run or if you remove the temp. sensor and manually cool it a start condition will occur.Ther are no codes present. Any Ideas ?
