Hello, first of all I want to say sorry for being the new guy that posts a new thread right away.
But after reading multiple threads of similar problems I can not find what im looking for.
Earlier this year I was given a K11 micra 1.3 -1999 the car was going to scrap.
The previous owner said that the car was running fine and then suddenly stalled and had to be towed.
After some troubleshooting with my friend we found out that the trigger wheel sensor that sits inside the distrubutor housing was bad. After replacing the sensor it started right up. But when it reaches operating temperature it stalls. It can however be restarted but then it runs rough and than stalls again. After the second restart it wont start anymore untill it has cooled down. Then it runs like a dream again. I have read that often times the cold start valve is bad and needs to be calibrated. This is not the case here. When I floor it when turning the ignition key it wont run.
I have come to the conclusion that something electronical fails when the engine is warm.
I get ignition, fuel preassure and compression.
I Replaced sparkplugs, ignition cables, coil, distrubutor, distrubutor cap, water temperature sensor, fuelpump, and timing sensor inside distrubutor housing.
I also did the throtle housing resolder without any differance.
I took apart all 5 blue relays to the left of stering wheel. No signs of wear. Took apart the engine control unit again looks like its factory new. No signs of moisture or bad solders.
I cleaned engine grouning points and even added an extra jumper cable from engine to body with no improvements.
Could it possible be a faulty engine control unit or an faulty immobilizer or possibly something related to ecu ir immo?
Sorry for my novel / Max
