If there is fuel and spark,it can be one of two thing,s,timing is off,or the ECM is bad,


I had the timing checked. It's okay. I even bought and tried another ECM. Is there something I need to due in order for the new ECM to work?


You may need to program the ECM to your car. Or if your car has a anti theft system it may need to be reset.
