You must ensure that you place the correct measurement belt Check belt tensioner I think the water pump failure does not match the noise

1) go to a gas station with an air pump. Unless u have an inflator/compressor at home with the tireattachment 2) lower all 5 air pressures including the spare in the trunk to maybe about 28 PSI 3) now reset the TPMS (on the 07 there is a button to "calibrate" the TPMS and it is located under the dash. I presume it is the same on the 08.) 4) now bring the pressue back up to 30/32 or whatever it says on the door area If this doesn't work, it is possible u have a defective TPMS but my bet right now would be that someone "calibrated" the TPMS to the current tire pressure so the light is constantly on. It happened to me before when my daughter was messing around and hit that button.

It seems to me you may need to replace the low pressure sensor located inside the rim.

You must remove the coils that cover and go over the spark plugs.

Usually not. Most vehicles I've worked on have had the brake lights and 3rd operate on 2 different systems, likely as a safety measure.

Sounds like the new system you installed is piggy backed off of the main brake circuit and popped the fuse.

sounds like a timing belt issue. Toyotas will run forever if you change the timing belt every 100,000 km, or 65,000 miles

Idler bearings are very common, they can also reduce the timing advance, reduce power in the engine

You can find it in less than thirty seconds using my method. Instead of wasting time searching for the exact location, why not just remove each fuse 1 by 1, and keep putting them back (if good) as you go so you don't mix them up. If you have any blown fuses, you will find it! If you don't know the difference between a good vs blown fuse, ill post a picture to help you identify.

The problem is more than likely a dead cell in the battery, Each cell in a battery is normally 2.3 volts, they will go over but when rested will return to 2.3 volts, with 6 cells it is 13.8 volts, car starts. 5 good cell is 11.5 volts, almost enough to start, any less not a chance, the starter will just click, cold weather is worse. A new battery will solve the problem

Was the battery disconnected by chance or replaced?

You need special tools and training to check the function of the system. The dealer is really the only choice here.

I believe you've hopefully managed to get into your car by now... In any case, you can use the key from your fob to get into the car (( Yes, the old fashioned way!! ))...First up, you need to take the key out of the Fob (( obviously )).. In the driver/passenger side of the car, on the handle, to the right corner (( beyond the part which comes out when you pull the handle )) that Silver part on the door handle actually comes off!! Dont worry, you can pop it back in, you will not damage it... To get that small silver part open/pop-out, you can insert the key from UNDER the handle, to the right corner again... there is a small hole big enough for the key from the fob to go in, use that slot to pop out the small silver part, and voila! You get to see the normal key hole, where you use the same key and turn it to open the door!!With the battery dead, I do not think you can open the trunk (( dont think there are any secret entry points in the trunk, i've not found any :) )), but you can get access from the back seat... (( Keep the jump start cables near the back seat :) ))Hope this helps...

Check you owners manual it is in there.
