make sure that cylinder has compression first, then if it is ok, make sure coil and injector wiring is ok-no open circuits or shorts to ground or power, if everything checks -
OK replace PCM
To start with I know nothing about cars other than if it has gas and I turn the key it should run. That's why I count on my mechanic and according to the garagethe compression tests were done and everyting is ok. What is a pcm?
