The power door light stays on in my 1999 Sienna

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.

Replacement spark plugs

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

99 Toyota Sienna 3.0 won't start. Replaced fuel pump. Plenty of fuel but very weak spark.

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

99 sienna, fuel pump changed out & can hear pump humming wen key turned on but it won't start..it almost starts but nothing..dnt have diagnostic tester

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.

Front Passenger door lock stuck

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!
