How loud can they be? Is it a sign of failure? My #3 injector gets fairly loud if it is indeed the noise I am hearing, more so once it warms up to operating temp. The car takes a fraction longer to start on cold mornings which makes me think injector issue.
When I first heard it I expected "the tick" but after using a heater hose to listen for the sound. I think it is coming from the injector. I can clearly hear every injector's pulse with the hose, but #3 is way more pronounced.
