1999 Toyota Sienna - Answered Questions & Fixed issues

There is a little silver bumper on inside if the T screw is loose the door light will stay on. Go to hardware store and get a T 30×4 and tighten the screws and then the light should go off. Mine comes loose time to time especially in the cold.

start with the code go have it read most auto stores offer service for free instead of blindly throwing parts in --abs can be sensor wiring brakes or hub need to check and test vehicle sounds like in limp mode code and abs repair should reset it

Check you're alternater, and battery to see if they are working properly

the plugs will be fine the gap for electronic ignition can be up to .55" how you pulled the rubber boots from the old plugs determines if you damaged the plug leads as the leads will not stand being pulled on you may need new plugs leads next misfiring , missing is seldom plugs but dirty injectors or low fuel pressure a point here--- plugs fitted to efi or ECM controlled engines will under normal operating conditions outlast the engine as they are not subject to the high current of the older engines

Cheked the fiuse and replace them

Have you performed a fuel pressure test? Does the vehicle even try to start?

This could be normal. You will need a constant power source at the radio to maintain clock and station memory

Check for proper fuel pressure, 44--50 psi. If your going to work on your own vehicles, you need a few basic test instruments, other wise your just spinning your wheels, hoping you get lucky and find the problem. You need a fuel pressure gage with the proper fittings to hook it up, if no Schrader valve. Also, you need an obd2 code reader, a basic tool. Some of them don't cost that much. Check fuel pressure--visually check for spark at all the spark plugs--check for fuel injector pulse. Check valve timing.

Hi Andrew: Many local tow truck operators know how the latches work and use a tool called a slim jim to trip the latch. If you really want to give it a go yourself, I'd remove the interior panel on the drivers door so that I could see exactly how the mechanism worked. Using that knowledge, you'll have to practice using a skinny tool, wire, whatever works, to unlatch the drivers door. Once you've got it figured out, apply the mirror image of that process to the passenger door. When you achieve success, you will be well on the way to becoming a tow truck driver. (or a car thief) Happy Happy!

COULD IT BE THE VOLTAGE REGULATOR?

Check the cambelt is intact. Do not turn the engine over, i.e. crank it until you have some kind of idea what it might be, you could be causing expensive damage GOOD LUCK

The code should not have any effect on if the engine runs or not. Code 500 is for a problem with the speed sensor in the transmission. You'll need to find out if you are loosing fuel or spark when the engine stops.

The cylinders closest to the front are from left to right 2,4,6. So the injectors are in the intake manifold under the fuel rail the connects these three cylinders.
