When trying to start the starter spins but engine won't start this is why.

[Ralph Blake]

Around seven years ago i tried to start my 4Runner, starter was spinning but engine would not start, what the reason i found out.

The reason is when battery voltage falls to around ten volts, the engine control computer will not allow the fuel pump work, you put in a new battery and the engine then will starts

Seven years ago this had me shaking my head, today it again happened i quicklychecked the battery voltage and it was ten volts, went out bought a new battery and again engine started.

Undervoltage can cause some strange symptoms. My favorite is when all of the locks and relays start chattering!

Here is a picture on my 08 4Runner's Odometer as of today 09/16/2022 (9063).
I keep trying to drive it more but fear someone cutting it's cats off, have enough problems with jerks keying it.

On my 2008 T4R......when the battery starts to go......the first indicator is that the rear window wiper will cycle a couple of times.

Never had an engine start problem, other than a slowing cranking function.
