88 Olds Firenza 2.0 OHC "K"-code (GM of Brazil) engine runs for 10 mins when cold, then stalls and won't restart until it cools down again. Fuel pump, ignition module, pickup coil, O2 sensor, ECM have all been replaced. Has spark and pulses to fuel injector, fuel pump relay is good... actually starts and runs for 2 seconds, then dies. Apparently ECM is not receiving signal that engine is running when warm. Any ideas? Thanks.
