I had technician check that and everything checked out. Anything that has to do with fuel has been changed and is brand new. It is a new engine had local motor company put it in I have a lot of money tied up in the car and it still dont. I had several technicians look at it together they have over 100 years experience in this feild and not one could fix it

Its suppose to work that way but at times they'll be a problem within the engine management system that the computer failed to lock-in and pop the CEL. Scan the computer again might give you something
