Hello,

I have 2000 Toyota Sienna LE. It has about 128k miles, but I've always kept on top of all the maintenance. The tire pressure light has been on for the last 3-4 years, and after tons of different procedures, it still stays on. That's not really the issue, though!

When I start my Sienna, I would always hear a whooooooom right before or after ignition (depending on how long I left the engine on before firing). I assume this is the ABS system kicking in. However, today I tried to start up, and it failed. The "check engine" and "ABS" lights came on. I figured it was an anomaly, so I fired again. It did start, but the "check engine" and "ABS" lights remain on. I do *NOT* hear that whoooooom ABS sound.

The van is drivable; I had to move it between parking lots. However - and it could just be paranoia - it seems like it has lost some oomph; usually the gas pedal is really sensitive, but today it was not. Also, it could have been because I didn't drive it around long enough, but the temp gauge never moved from it's dead below-zero point.

Is it safe to drive? Should I pick up a code reader? Take it into the dealer? Since various lights and warnings have always gone off, I'm mainly concerned about a mileage hit or my brakes locking. Any help would be appreciated!

Thanks

The Whoom could be the fuel pump.

Thank you for the reply. The dealer said the noise was the ABS -- but the fuel pump actually makes sense.

The van is actually having a TON of trouble starting. It actually fires and turns over, but as soon as it turns over it either stalls or shuts off immediately. Sometimes it starts until I touch the gas pedal (once it's shifted into gear).

Now, the only way I can start it is to:

1) Get lucky

2) Shift into gear as SOON as it turns over

3) Don't touch the gas pedal; let it drive itself around for awhile

Once it's running, it stays on. The temperature gauge still doesn't work. I hope it is the fuel pump - it's not in-tank so it could be an easy and relatively cheap fix. The symptoms definitely fit.

Thanks for your help; here's to hoping it'll start so I can get it home to work on it!

actually the fuel pump is in the tank:biggrin:
