Running, not reading; what engine option? Cyl count and displacement?
Is the CEL glowing key on, then turns off running> (check engine lamp)?
the engine RPM is too low. ok that is bad.
this is caused by up to 50 reasons. (flooding and misfire huge list )
ill just post the basic physics reasons.
(Classic, good compression, spark and fueling)
no fuses blown?. and 12vdc reaches all EFI parts. (weak battery is no go)
In generic form as there many engines used on corolla world wide.
1: low compression , less than 150psi on all 4. (if not V6)
if engine has cam belt? it slipped.
2; weak spark causing misfire, tune ups never done each 60k miles.
3: bad fueling. (too much is flooding misfire, if too little it starves)
4; EGR stuck open , we clean these ever 60k mile.
if it sticks open, idle will fail. (goes low) for sure.....!
5: the ISC sticks closed, same deal; so it gets cleaned.

The first thing to do is a tuneup per the FSM and operators guide.
the 60k it's called, do that and spark is good and fuel pressure returns.

this post assumes engine has full power at all times.
if not , better explain that, in details.

there are simple tests for all the above, $100 max i tools.

SOURCE: 2002 toyota corolla power windows stop working

Probably a resetting circuit breaker in the system. Some are reset when they cool off, others when keyed off. Must be something drawing too much current, or circuit breaker getting weak. Usual causes of drawing too much current in your case would be power window motors. With that said, there are some things you can try to lessen the load on the circuit such as spraying silicone down sides where felt is for easier window movement. Those areas get dried out and tend to grip glass as it's going up & down causing extra load on motor. I've also had to resort to removing door panels & spraying grease on tracks & guides inside door, to help. try silicone down sides first and see if it helps. Also make note if one window seems to cause it more than another, that gives you a good one to start on.

SOURCE: my toyota corolla 94 window driver side can not scroll up&down

Perhaps a faulty window-motor, or the window switch.
Make sure your battery is good. Usually the problem is the window-switch.

'06 toyota corolla loses power while driving


The power steering works off the engine, so if engine not running, no power steering. It sounds like to me that a good place to start would be the fuel filter. If the fuel filter is plugged, it may allow enough fuel to go through to run the vehicle for a few minutes but not allow enough through to sustain continued operation. The fuel pump is also a consideration.

You need to have the dealer look at this, if you fool around with it you can void your warranty. Toyota looks for any legal excuse to void the warranty.

Possible exhaust restriction.
Could be cat converter.
You can try and unhook the exhaust system and try it.
If the car will run a few minutes try a vacum guage hooked up to engine vacuum.
If you get a very low reading that would be your answer.

1989 toyota corolla will not start


You have soaked all your electrical. All you can do is get an air hose and try to blow everything off as well as you can. Take apart what you can, and blow it out. If it doesn't go, you'll just have to wait.

Overheating engine: termo guage at the middle during idle


The Temp gauge should read in the middle of the gauge at operating temperature. This is normal. The radiator fan should come on after idling (not driving) for 20 minutes. The fan should also come on when you turn on the AC. Are you experiencing overheat problems?
Please reply if you have overheating issues.
