Hello, thank you for helping me figuring out this problem.
I measured the resistance in the injectors in my Aveo and all of them show zero resistance. I am having very hard start (car cranks normally but wont start) when car is cold and gas consumption has increased. When car has warmed up it starts just fine.
I replaced spark plugs, ignition wires, checked the fuel pump and it maintains pressure at 56 PSI, no pressure drop noticeable after car is off. Battery is good, checked the intake air sensor and seems to be working fine. Coil seems to be giving spark (although it look a little yellowish to me) also checked for vacuum leaks and it seems fine.
I listened for the injectors and they sound click, click as if they would be working fine, but the resistance measured with a multimeter shows zero in all of them. Is that normal?
I try to look for fuel pressure regulator but was unable to fine.
I find strange that all of the injectors show zero resistance. Can they all go bad at the same time, yet the car runs fine after it starts?
have the same problem?
