That sounds like the starter is engaging. Dunno if starter motors have changed but I haven't learned anything new since I learned about them 17 years ago: AFAIK they're series-wound, so if they run with no load, they will keep going faster and faster (drawing more and more) until a fuse blows or they break. It'll just be a whizzzzzz, and the "dip" in your noise sounds like it's engaging.

Pressing the pedal will do nothing in ACC or ON with the car not cranking or started. This is a fuel-injected engine, so the computer determines how much fuel to add after determining airflow. Unlike my carbureted Hilux, where pressing the gas pedal dumps a little spritz of fuel to help with starting.

EDIT: Lol I've been screwing up answering of late. If you're cranking (and you have compression), then what else you need: air, fuel, spark. Should be easy to check those out.

Good to hear. The noise seemed to be a bit too fast to me than I was expecting.

I was expecting noise like I get when doing compression test but maybe this is how to sounds like then one is inside the car

I have never been inside the car when trying to fix car issues, but today I am alone and lost on how to go about it

I am not sure about this: on my 99 Camry, it often fails to run and I have to feather the pedal a bit to persuade it a bit. If I do nothing, it will die. There is an Intake hose leak on that one. New Intake hose on the way.

So what should I be doing next?

 

Did you ever figure this out? Can't search if you posted a new thread.

It's turning over quite fast as if it doesn't have compression. Check timing belt?

 

I did not figure this out. Had a mechanic friend come over and the car was rough on start so he quickly pumped the pedal like crazy and it started right up.

Has been running perfect ever since (although recently it sounds like it's taking 3 seconds for the starter to start the engine)

 

That is not the normal sound of that motor (assuming its the 4 cylinder). Starter is turning too fast and sounds like poor compression on some cylinders.

Possibly due to dry rings from oil drain off or timing tensioner loosing prime.

My 98 Corolla did the exact same thing for a few years if it sat for more than 3 days. It also would eventually start, run bad, and tap loudly until given gas. It would eventually smooth out and the car was back to normal until the next time it sat. I eventually traded it in and a few months later I heard the engine locked up on the new owner. I don't know if the issues were related to its death or not.

Uh oh!

Will take some sound samples next weekend. ISB hates my sound samples though. >

The Camry has been running perfect since then and I also did a TB job on it, but there is a delay (3s) in the start during which my heart jumps a little :surprise:

 

Can you post a video or audio of the start up delay now that it's running again?
