Question. I want to boroscope my pistons in Sienna 2008 2GR-FE, extracted sparks and see that the needed piston is in upper position. I would need to rotate engine crancshaft to move pistons. A good idea to use ignition and rotate crancshaft by trying to start the car, but to prevent engine from actually starting (most likely one side will have 3 sparks and another side will be 3 out). So, would it be a good idea to remove fuel pump relay and rotate the engine by ignition key, or should it be EFR relay?
Good evening, if you would excuse me, I have a 2014 Accent car and there is a problem with the air conditioner. If I turn on the air conditioner, it starts and turns off all the time, meaning it does not sit for 20 seconds and turns off. What is the cause of the problem?
