How to change fuel pump on a 2008 toyota sienna

Yes there are two fuse blocks on the van. One in the engine compartment and the other under lower dash panel fronting driver. Use a circuit light tester to probe the power terminal on the washer pump first to determine if you have power coming there when you turn on rear washer pump switch. You will need another person to help. Rear pumps fail often because of the lack of usage

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

Sounds like either the fuel filter is plugged or the fuel pump has malfunctioned.

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?

sorry no quick fix ,fault with electrics ,encrypted software dealer only

not the pump.... unless you plan on keeping it for ever ....

If the "evap not ready" readiness monitor never clears and you keep getting P0440,P0441,P0446 type codes, then you have a problem with the evap system. You have already tried the gas cap (good start) but there are about 6 other things it can be from electrical VSV air valves (there are 3 of them, 2 under the hood, 1 near the charcoal cannister (behind fuel tank) to 2 air operated valves on the front of the same cannister. There is also an air line that goes to one of the electric VSV valves on the air cleaner under the hood. Several oil change places have been guilty of pullling these off and not reconnecting them.

check the alternator and see if the battery light is on on the dash. if the light is on then the alternator is faulty. or there might be a ground somewhere...

a local auto parts store will have every thing you need including manuals

I would replace the battery, purchase and install an oil filled battery warmenr, and purchase and isntall an engine block heater.
