Tip & How-To about Chevrolet Malibu

Car trys to start but won't Car acks like it wants to start but won't

This problem can be from a problem with the security system. To test this theory on most cars turn the ignition to on and see if the security light continues flashing. If so this may be the problem. Most owners guides will tell you how to reset the system so the car will start. If not, one thing to try is leave the ignition on for a long time (10 minutes or so). When the security light stops flashing the car should start. This problem seems to be from the car ageing and the key not working as when the car was new.

We have used compressed air in the ignition and then put wd40 on the key and run it in and out. This seems to help with the recurring problem but doesn't make it go away.

I don't know the permanant fix. I suspect a new ignition switch which is not a cheap fix.

How do i reset the alarm on my 2003 Chevy Trailblazer...I can't stay my truck.


Hello Narisol,


Excerpt from the 2003 Owners Manual.


Passlock

Your vehicle is equipped with the Passlock theft-deterrent
system. Passlock is a passive theft-deterrent system.
Passlock enables fuel if the ignition lock cylinder is turned with a valid key. If a correct key is not used or the ignition lock cylinder
is tampered with, the fuel system is disabled and the vehicle
will not start. During normal operation, he SECURITY light
will turn off approximately five seconds after the key is turned to
RUN. If the engine stalls and the SECURITY light flashes,
wait about 10 minutes until the light stops flashing before trying
to restart the engine. Remember to release the key from START as
soon as the engine starts. If the engine does not start after
three tries, the vehicle needs service. If the engine is running and the
SECURITY light comes on, you will be able to restart the engine
if you turn the engine off. However, your Passlock system is not
working properly and must be serviced by your dealer. Your vehicle is not protected by Passlock at this time. You may also want to
check the fuse. See Fuses and Circuit Breakers on page 5-85.
See your dealer for service. In an emergency, call the M
Roadside Assistance Center. See Roadside Assistance Program on
page 7-5.


Excerpt from the 2003 Owners Manual.

Testing the Alarm The alarm can be tested by following these steps:
1.
From inside the vehicle, Iower the driver's window and open
the driver's door.
2.
Activate the system by locking the doors with the power door
lock switch while the door is open, or with the remote keyless entry transmitter.
3.
Get out of the vehicle, close the door and wait for the SECURITY light to go out.
4.
Then reach in through the window, unlock the door with the manual
door lock and open the door. This should set off the alarm. When
the alarm is set the power door unlock switch is not operational.
If the alarm does not sound when it should but the headlamps flash, check to see if the horn works. The horn fuse may be blown. To
replace the fuse, see Fuses and Circuit Breakers on page 5-85.
If the alarm does not sound or the headlamps do not flash, the
vehicle should be serviced by your dealer.

i have a new battery and alltinator but my car still wont start


Have the starter tested! Check the cables to see if they are in good condition. Check the cable that goes to the starter. They all need tight connections.Don`t know the year,make and model. but older cars have a solenoid switch that is not on the starter.

We bought the car today from a private seller. We test drove the car and shut it off several times in our 30 min test drive. We shut it off at the store and now it will not start. We tried jumping the battery and everything else we could think of. It is a 97 aurora. The lights and radio still come on but it will not crank over... I do not know what to do but my hubby is not happy...Please give us some advice. thanks Sara


It could be corrosion on the battery terminals. Otherwise, you sometimes can't get a car with a dead cell in the batty to jump start at all. I would call the seller and politely ask their advice.
Treat them with respect, and they will probably be very helpful. Don't start accusing them of things. That just never ever helps.

Sounds like your Passlock security system went into the tamper mode. If your dashboard security light blinks when the ignition is turned on, your Passlock security system is disabling the injector module, preventing the car from start. Try this:
1- turn the ignition on and just touch the starter, without getting the motor to fire, then leave the ignition in the "on" position. The security light will blink for about 10 minutes. When the light stops blinking, turn the ignition off and leave off for 3 minutes.
2-repeat the step #1, 3 or 4 times. You will know that is fixed when you turn the ignition on and the security light does not blink, then the car will start. Make sure to stay inside the car when you're doing this, as opening the doors will trip the security tamper mode on again. Once the tamper mode is off, the car starts and opening the doors will not trip the Passlock tamper mode.
