Expert:  BOBBYSS replied 7 years ago.
Okay. Does the vehicle crank over just fine? Is the security light on while cranking the engine? Did the vehicle just not start one day?
Customer: replied 7 years ago.
There is no security light on while cranking over and it does turn over fine and sounds normal and it hasnt been ran in like two weeks then went to start it and would turn over but wont start
Expert:  BOBBYSS replied 7 years ago.
Okay. You need to start by adding fuel directly into the engine. This will let you know if the injectors are firing. If the engine then attempts to start then the problem is fuel related. If it still does not then you may have a timing issue which can be caused by the crank sensor.
