Where is the starter located in the 2004 scion xb?

That is a mess and points to nothing in particular, perhaps a communication issue with the BCM?

You need an auto electrician with a professional grade $5,000 scan tool computer with access to wiring data and the ability to read wiring diagrams.

I know you are looking to have the remote starter run a third time but I would say you need to look at your Fuel Pressure Regulator on the Scion. Sounds like it is not holding fuel pressure at the fuel rail and that is why it requires a third Crank

You car have security system.first locate the security light and make sure goes OFF after unlocking the car
turn the key and monitor the instrument cluster if all the light stay on
apply parking brake and whit left hand turn to starting position and with right sift from PARK to NEUTRAL
locate the starter and connect test light to small signal wire,other end to ground. let helper start the car. did the light go ON?(replace the starter)
the light stay OFF (electrical problem)
Inspect all the fuses,switch the starter relay with known good one,clean battery terminals,scan with advance scanner for malfunction code,and switch to live data Look for starting signal from computer
good luck

it could be a billion things...might have to specify that is it doing...
if it doesn't start but cranks...then check the starter,battery,and the alternator...
it could also be the fuel pump isn't pumping fuel in to the engine...so you need to check that too...
Good Luck!

There is a black locking ring holding the bulb in. After disconnecting the electrical connector turn the lock ring approx. 45-90 degrees counter clockwise, remove the lock ring then pull out the bulb.

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.

Hi.. Yes i fix my problem by disconecting the neutral suitch and reconecting it ,,they get dirty with time and dont make contact ,Is a good idea to disconect and clean as many contacts as you can and put some special grease on them to prevent other problems ...
