any ideas would be appreciated.

Not an obvious source. Have you checked your oil? Last oil change? Oil weight used?

 

the Atkinson cycle motor makes a ticking type sound when it runs.almost sonds like lifter noise.thats the 3.5 engine in the Tacoma's they do that.

 

Sounds like your high pressure fuel pump. I think there was a TSB for some of them chirping

 

Sounds like your fuel pump. They’re high pressure pumps, i think from what I’ve researched that it’s normal. Mine does it too, almost like a bird chirping noise.

 

The chirping like that is not normal. You might hear the pump a little with the hood open. but it shouldn’t be high pitched chirping the sound in the video

 

Yeah... it's your HPFP, but if it sounds like crickets, Toyota should replace it. Many say it will come back though. If
you buy the same brand of gas all of the time, you might consider switching for a while to see if that helps.

 

Fuel injector cleaning. Normal.

The injectors only clean on a hot cycle at idle after a computed amount of time/cycles

Also on a normal pump it doesn’t have that kind of pitch

 

Hmm, I might bring this up to my dealer next time I’m in for service then.

 

oil change around 30000 with mobil1 extended performance 0w20. also replaced the oil drain nut with a fumoto drain valve. not sure if the chatter is coming from that.

 

i don't religiously check this forum. care to explain?

 

It's your HPFP (high pressure fuel pump) like others have said. Clicking is completely normal mechanical sound. Chirping is not. If it's chirping take it to a dealer to have the tech preform and diagnose for the TSB repair. Mine was replaced and no more chirping. Chirping, not clicking. It is that specific.

 

Both of my tacos i ve had had this tick Normal.
