Question about 2008 Toyota Sienna
Van stopped in the middle of the street with no warning. Seems like a fuel pump but no pressure test port on the engine. How do I, with some amount of certainty, determine that it is the fuel pump. Should this pump make noise when the key is turned? Most of the in tank pumps make some amount of noise.
No solution here, but wondering what your next step was...I think the same thing happened to me, but wanted to check the fuse at least before I have my van towed to some mechanic in Italy. Did you locate the fuse? Which box and was it labeled something other than fuel pump?

Hi There. Have the exact same problem on my 95mod petrol with the sub fuel tank not emptying. think it may be the relay but cant find it. The earlier models have the relay in the rear wheel well, but ours are set up differently. had the whole car to pieces but still cant find it. Was wondering if you had any luck with yours and could enlighten me. Thanks firstname.lastname@example.org

A friend of mine had the same problem and found a relay on top of the reserve tank that was filthy and gummed up. We gave it a clean etc refitted it and he hasn't had a problem since. I hope this helps.

The Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.
