Did you replace the engine coolant temp sensor and harness?that will set a p0341,p0340 code and cause hard.no start as it misreads and dumps too much gas,,,,,the sensor is plastic and sits inside the head and crakcs and leaks into the harness and corrods,,,,,,you need a new updated brass sensor and harness,you must do the harness,its a pigtail you wire in,,,,,do not buy autozone junk they misread you need the saturn sensor and connector,like $70 for parts,,,,,,,that will fix it,,,also do not run platinum spark plugs that will set the light as well
