Question about 2008 Toyota Sienna

1 Answer

2008 sienna, How do you check a fuel pump with no test port for fuel pressure check on the vehicle.

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?

SOURCE: Toyota Land Cruiser fuel tank warning light on

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

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.

Hi i got a toyota tarago 96 model that wont start my wife was driving and she heard a bang then the car stopped in the middle of the street so i changed filters n spark plugs n pumps still no start

There are videos on you tube for diagnosing vehicle no start problems ! Rather then just replacing parts . Testing for spark and fuel pressure and engine compression . Timing chain problems etc... My advice to you would be take your vehicle to a qualified repair shop . Save yourself some money . You spent how much already ? i changed filters n spark plugs n pumps still no start !!!!!!!

The engine will crank but will not start why?

Do you have any codes or an engine light on, in your dash board ? Have you checked for spark at your plugs ? There are many things that could cause a vehicle to not start. Bad camshaft/crankshaft sensors. Poor ground wiring. Defective spark plugs or wires/coils.

How to change fuel pump on a 2008 toyota sienna

The fuel pump is inside of the fuel tank. You will need to drop the tank and remove all of the attached hardware like fuel inlet hose, pressure and return lines, and electrical connectors to access the fuel sending unit. It would be a good idea to trouble shoot your issue before assuming it is an expensive part that is not easy to change. I would verify that there is a low fuel pressure condition at the fuel rail first.

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 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.

My ford fiesta van needs hand priming after 4 hours so van can start - why is this?

Could be bad diaphragm in fuel pressure regulator, leak in gas line or a check valve somewhere. Your problem continues to the fuel pump because the pump should quickly restore pressure in seconds and it is not doing it.

So both problems can be due to 1 part, but it can be 2 separate problems, losing pressure and then failing to restore pressure.

A fuel pressure gauge can be attached to the test port on the fuel rail. The term used is "bleed down" test. It can help diagnose what is going on.

My 2004 sienna hit bumpy corner express road at 45mph, seconds later the whole van shakes like I'm driving on 4 flat tires then vsc and check engine light comes on. The van refuse to move as if I


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.

My van just started to have a problem, i was driving home and it started to potter. almost home it was getting worst then just stop. left alone for hour it started up my husband change the gas filter,...

Hi, your fuel pump may be failing. You can check the pump by removing the clamp from where the fuel line attaches to the fuel rail. Pull the hose off to see if there is fuel pressure there. If no pressure, check to see if you can hear the pump coming on when you turn the key on. If the pump is coming on, it's probably bad, but you may want to try cahanging the filter before getting a new pump. If the pump is not coming on, try checking the pump fuse first, then try swapping the fuel pump relay to see if it will come on. Please get back to me if you have any questions, and thanks for using FixYa.

1999 Chevy Astro Cargo Van.Where is the fuel pump and how do I test it.Van won't start.Please help.

Hello eleazzrismo; my name is Roger and I will help: The fuel pump is located inside of fuel tank. The fuel pressure test port is on top of the engine.Just to the right of the throttle body. You should find a port with a schradder valve in the fuel line. Could have a metal cover like a tire cap over it. The fuel pressure should be 60-66 psi. Any less and you will have poor to no start. I have attached a picture to help identify the fuel port. Should you need further help please just ask. Please rate the answer. Thank You for using and trusting Fix Ya. Rogerrogerf1_10.jpg

Continues cranking. Wont turn over. what s my next step?

You mean it cranks but wont start (cranking and turning over are the same thing) When cranking, rap on the fuel tank, if it then runs, the pump is bad and will need to be replaced.
