Check all ground wires and make sure they are tight. Start at the battery, starter, solenoid switch.
SOURCE: 2005 xb won't start ... New battery and new
poss need new ECU onboard computer poss get second hand this has fixed same problem on vauxhall cavalier
SOURCE: i get power everyware,but starter won't turn
Check the owners manual for the fuse / relay center under the hood. they have a description of all the circuits controlled and a diagram as well. Check the starter itself for the small wire on the solenoid for power, this is the wire from the ignition switch. Sometimes theres another fuse pannel by the foot pannel near the floor. The neutral switch is usually at the transmission manual lever where the cable attaches for shifting, not on the gas pedal. You will need two people to test the starter, one to turn the key and another to test for power at the solenoid. If there is power but it does'nt crank, replace the starter. If it has a clutch pedal / starter switch, you can bypass it by jumpering the terminals with a paper clip. My Ranger has one at the top of the pedal and pushes a slide contact to let the starter engauge.
Hope this helps, Craig
SOURCE: i have an intermitent problem. 06 xb, will start
check ground ******** top of trans to body remove bolt in trans holding ground wire clean with wire brush and reinstall had same prob at dealership took me 2 days to figure out wasnt dirty however it was repair please let me know and please rate this
Testimonial: "didn't fix the problem, but was an inexpensive place to start. i appreciated the suggestion. will go next to starter relay, then to ignition switch."
SOURCE: why do the fuses on my scion xb keep blowing?
Did you check to make sure the fuses are the right rating to begin with. Fuses are rated by amperage and disconnect the circuit or "blow" if there if the circuit is shorted out (+ touches - or vice versa) or a device or circuit draws more amperage than the fuse is rated. Did you buy the vehicle new? If not then there may have been modifications. Does is have the stock radio? Does it have an amp or subwoofer? Driving lights? There is also a fuse block with relays and fusable links under the hood. Refer to the owners manual and verifiy all the components in both fuse blocks are of the correct type and rating. Physically remove and inspect every related fuse and make sure no one has "jumped" a fuse by wrapping it in foil or ataching a solid wire across the connection. If all that works out ok, have the voltage reguator checked as it is regulates a constact rate of power to the car. If is is allowing momentary surges, it is possible that it could exceed the cirucit ratings especiallly on the 10 and 15 amp circuits that most of your accessorys and lighting use; Good Luck.
