Check the internal resistance of the injector..compared to the others. Give me engine code..and i ll tell you exactly how much ohm there should be, and the power that needs to get to the injector. Also you could swap injector to rule out posibility of being the injector or the cable connector.

this is error

Hi,
Does the engine ecu has been opened? If it has been opened then problems in ecu.

after 10-15 min ??? could be the power output transistors inside ecu. Oopen Ecu and see if they get really hot, also buy a spray that cools electronics, it is a cold spray that you spray over the hot components and if the car starts running again then you know where the problem is.

Also check all the cables from injectors to ECU

hi
i try with hot air and cold spray but i think problem not in temperature

if cooling down the transistros(mosfet) or other hot components inside the ECU, makes the engine run well, Then it is a ECu problem.
