Failing injectors!!!!

[briank213]

I have a question I got a call from the mechanic saying that all 4 injectors failed on my car is that even possible?Let me know if this ever happened to your car.

Thanks have a great day everyone

All 4 does sound odd  - have they checked the wiring?
Sounds more likely to be an electrical issue stopping the injectors from firing

Utter BS!!

No they have not they took the injectors out of the car and bench tested them that's what the mechanic told me cause he quoted me
$900 for 4 new injectors.

That's exactly what I thought cause I never heard of all 4 failing at the time. I am going to go to the shop tomorrow and he must show me how did these injectors failed. His reason for all of them failing was because I had Apr stage 1 tune on my car.

They very rarely fail completely, and NEVER all 4 at the same time.  They just get lazy/blocked at lower duty cycles (i.e. idle and part throttle) but clear up again with some revs and increased fuel pressure.

Sounds like he can't be bothered to properly diagnose the issue and wants to just fire the parts cannon at it, at your expense.
