2002 Sienna - Lost all Power

Hello All, I have a 2003 Sienna which has failed to start a couple of times now. When it fails, it turns over, but does not start. If I wait a half hour or so, it starts and runs fine. I'm thinking the fuel filter needs to be changed, but I can't find it on the vehicle. I have crawled all over underneath and looked under the hood, but I can't find it. I've asked a couple of parts houses where it could be located, but to no avail. The Internet has not been much help either. If anyone knows where the fuel filter can be found on this vehicle, the info would be greatly appreciated. Matt I have a 2002 Toyota Sienna, yesterday I lost all power - none of the gauges in the dashboard work, A/C does not turn on, Power locks and Power door do not work, I suspect I have lost the ABS too. The car starts and I can drive around. I am trying to figure out what would be the problem, the technician at Tire Kingdom told me that the computer is gone and I need to take it to TOYOTA, anybody has any input on this?

When I start my car and I turn on the radio all my stored radio station is erased and this is starting to happen all the time I start the car. Please advise what's going on with my car... Thanks!

Check your fuses. The radio needs residual power to keep the memory alive. When you shut the vehicle off it isn't getting that power so the memory gets lost.

2003 Sienna - where is the fuel filter?


To my knowledge after 2001/2, Toyota no longer uses an external fuel filter on their Sienna models, all the fuel filters are incorporated with the fuel pump inside the tank. Should your model still have an external fuel filter it would be underneath the air filter assembly. You could verify by following the the fuel line/hose.

Additionally, you may want to have your car's computer codes scanned/read, there may be indicators/errors. Depending on the errors/code displayed, they may be causing your intermittent starting which could be anywhere from the O2 sensors to the two A/F sensors or entirely something else.

Hope this be of initial help/idea. Pls post back how things turned up or should you need additional information.

Good luck and kind regards.

Thank you for using FixYa.
