Exactly as the title states, my 2000 auto 2.7 will fire up normally when it is cold, but after reaching operating temperature if you turn off the car it wont turn on again., it will crank and turn over but no start, It was doing this prior to cleaning the throttle body and maf. (btw that fixed the erratic idle) but once it hits operating temp it wont start after shutting the engine off. any ideas? My search has led me to single out the ecu or coolant temp sensor but maybe one of you guys have had experience with this issue before. please help. miami weather is too beautiful right now for me to be driving my boring nissan frontier! :(
