At times my car eill start & idle fine then other times it will start then die.There are no codes no warning lights/ I had a turn up, replaced the fuel filter used a good quality fuel injuector & replaced the battery. If I put my one foot on the brake and start the engine pop it into gear it will go if I am fast enough. If it starts 3 or 4 seconds later I can feel it dieing & try pumping more fuel but doesn't matter.
