The fuel injectors are not working as the should. Run some premium fuel and fuel injector cleaner to try and make problem go away. It problem persists the injector computer circuit voltages require checking. Possible injector controller or injector replacement could be solution.

Hi Darrell, I'm glad to help! Darrell, anytime you have an Injector Circuit issue, its either the Injector and most technicians will start right where you did, they will change the Injector first, so you did good there is just another problem. When the Injector doesn't fix the problem then you move on to the wiring and connector. You need to do a continuity check on the wires with an ohm meter while wiggling wires and see if you lose a connection. Also check the connector wire at the terminal to see if it may be broken inside the connector OR if the terminal is pushed down inside the connector and not making contact, also make sure the terminal is not spread so its not making contact with the injector pins. Check it the same way at the Engine Controller and if everything checks good then you know its a Injector Driver inside the Controller that's bad. Hope this helps and have an awesome day Darrell.

My 2003 CTS would not start on the first, second or third try after filling the gas tank. Finally after several months of this occuring every two weeks a check engine light came on. It was the evac purge valve. Tom
