Could possibly be the antitheft system disabling your starter. This is rather common on GM vehicles. The antitheft system can't communicate the "OK" signal from the key, so the it disables the starter or fuel injectors thinking it is being hotwired.

In most GM cars and trucks there is a hidden system that most people are unaware even exists. From the moment you put your key in the ignition, there begins a constant line of communication between your key's security chip or transponder, to the ignition's lock cylinder, and then to the car's TDM (Theft Deterrent Module). These 3 parts are in CONSTANT communication. If the key is in the ignition, then these parts are sending signals to each other. The security light illuminates when that signal gets broken, even just for a second. When the signal breaks, the car misinterprets this as an attempt at theft and goes into antitheft mode. The car thinks its being stolen or hotwired because it is not getting that signal from YOUR specific key. This is why the security light turns on and shuts down your vehicle. This link explains it pretty well.

Back passenger power window stopped working


I can help with a little testing. On the hinge side of rear passenger door, should be a wiring harness. Probably has a protective rubber boot covering, pull the covering back far enough to get at wire colors in the diagram. One wire is voltage the other is ground depending if the window is going up or down. Use a test lite to check. Key on, I would think.Your front passenger window works ok? If the wires check out good for voltage and ground, could be something wrong with window motor?

Car won't start, seems to have power, all lights working. when I turn the key nothing happens. this only happens sometimes


Could be a bad alternator.. It may not be holding charge. Or your starter could have failed.

Though I've had the same problem and it was a dead battery in my vehicle. Had enough power, but to keep the car on..

My 2001 Ford Expedition won't start from the ignition key. We replaced the ignition switch under the dash and it will start from there. You can turn the accessories on from the key, but if you tur


re-check the electrical connections at the switch sometimes during replacement terminals become bent or even pushed back to prevent contact

Turn key wouldnt start


Possible causes, flat battery, faulty alternator, coil or starter motor,though sounds more like power problem, do you have power to lights, radio etc when key is turned on even though nothing happens.

The car is starting 1/10.. Firts i turn ignition key and the light in the dash are lighting up good,i turn the key and nothing happen.I take the off the ignition and it make a tic-tic-tic on the...


We have to assume the battery is usable, if not, anything else doesn't help. A couple of possibilities- First, get a simple, cheap device that uses a 9V battery and the car's cigarette lighter to prevent losing anti-theft codes. Once this is plugged in, remove the negative battery cable first, then the positive. CLEAN the battery connectors and terminals. Try to start the engine. If it still does the same thing, remove the negative battery cable again and follow it to its next connection and clean that point. While it is off, remove the other end of the positive cable which goes to the starter terminal and clean both points.
While under the hood, look for the cable connecting the engine block to the body of the car and clean both ends of that cable.
If the problem is still there, it can be related to one of these; the ignition switch, the starter solenoid or a corroded fuse connection. The starter is not protected by a fuse but the solenoid may be.
Good luck-

Turn key on, everything tur on on panel lights are bright ,tried with power pack does nothing but click


It sounds like a starter. But double check your battery cables are cleaned good. Even though you are getting power to everything else you may not be getting a good connection to the starter.

95 jetta wont start unless you pop start it i changed the starter i have all the power just when i turn the key nothing


check your fuses under the hood and under the dash
check polarity of battery (if you unhooked booth leads)
is the battery any good?
you probly conected the leads to the starter incorectly (recheck them)

(the following asume your tur n key ignition system is functioning properly)
to test your tur n key system simply hook up a test light to the small lead running to the starter cylynoid "while the wire is disconected" and have a friend turn the ignition over. [dont furget to test the test light first lol]

or even got the wrong starter completly (usaly a store problem)
did you " bench test" the new/used starter befor installing it ?
iv goten brand new starters doa

is the ground strap hooked up ? is there corosian on the battery posts or any of the high amperage conections?

is the cylynoid on the starter or somewhere else under the hood?
cautiously try to bypass the cylynoid ie run a hot wire to the small lead on the cylynoid
(this can usaly be done by jumping from the main red wire on the starter to the hot lead of the cylynoid)

notes: when bypassing the ingnition system (jumping the cylynoid)
DO NOT have the ignition in the on postion and it is best to remove the lead from the cylynoid (incase of a short in the wire's some place)

if nothing remove the large red wire on the cylynoid and touch it directly to the starter lead itself (there will be a fair amount of spark when doing this its normal) but make shur you are conecting to the starter lead and not a gound point as this will cause exsesive sparking that isn't good
dose the starter tur n the engine over
back track untill you find the fault be it starter itself,cyclynoid,wiring,blown fuse,corosion,bad battery,

still cant find the problem take it to a shop!
hope i helped yah
