Question about 2006 Scion xB Wagon
Posted by Anonymous on
Mostly the only things that will stop an engine sensor-wise is the crank and cam sensors. Failure of other sensors will immediately cause the management computer to switch to the get-you-home programme, record the fault and switch on the engine light but will not prevent the engine starting and running.
Your description doesn't mention that you have physically checked the spark.
Another thing that prevents an engine starting is the anti-theft device. A friend happend to leave his keys on the microwave and couldn't start his car until it had been towed to the dealer.
Might be a good idea to check what the handbook says about that...

SOURCE: 2006 scion TC Hard starting
Does it start if you give it gas when turning the key? I had a grand prix that would not want to start unless I gave it gas. It was an easy fix. I changed the air filter, used MAF cleaner to clean the MAF and I also took the throttle body apart and cleaned that. The throttle body had a black build up in it that I cleaned up with throttle body cleaner.

SOURCE: My 2004 Scion xB will not start.
you may want to check the fuel injector. Check by starting the car then pull out spark plug wires one at a time. if you find that the car does no try and stall after removing any of the wires then its the fuel injector

SOURCE: 2004 Scion XB won't fire up!
What happened? Same thing happened to my chevy cavalier and it turned out to be the gasoline pump. It happened after 15 months again. Too bad its my wife's car, otherwise I would have gotten another Scion XB.

Your problem may be one of the following:
First check or just replace the fuel filter. Usually located under the car in front of the rear axle, drivers side.
Next, the fuel pump may be worn out. Usually they just stop working (running).
Next, check the fuel pressure regulator. Usually located on the front fuel rail, drivers side.
Is the vacuum line attached? Not leaking or rotted?
Also, do you smell a strong fuel odor when it won't start? May be one or more stuck-open injectors, or the coil pack is bad.
Checking these in the order listed will more than likely fix your problem.
The clicking noise indicates the battery can no longer run the starter, which also means the fuel pump won't run either.
It could be a fuel issue. How old is the fuel filter? Can you hear the pump run for a few seconds when you turn the key on? Try turning the key to ON without trying to start engine three times waiting for the pump to stop running each time. Then try to start the engine. If it starts, Its a form of Vapor lock caused by the extreme heat we have had lately.
If none of this works, try a new fuel filter first. From there have someone check the fuel pressure regulator and then the pump. If you are in need of a new pump, take my word for it and spend the money to get one from GM, and not from your favorite parts store. Most parts store parts are made in China and they are JUNK.
Have you hooked a scanner to the computer and checked the oxygen sensor(s)? If they are bad they could lean out the engine.
Also, a restricted exhaust system can lower engine performance. If you dont know old the plugs and wires are, replace them. With plug wires, its the age not the miles. How old is the coil pack? It could be "breaking down" at higher rpm
