Leading causes of not starting on these are a bad ignition switch and a bad starter. Needs electrical diagram and diagnosis.

Try this procedure usually works:
·Check the battery cable connections:
Make sure the negative cable makes a good ground connection at the battery and (preferably) at the engine. Make sure the positive cable, makes a good connection at the battery and at the starter.

·Check the battery the simple way, like this:
Turn on the headlights, then try to start the car.If the headlights do not dim or go out, then the battery is likely ok.

·Check the starter and solenoid:
If the wiring looks ok, then look at the starter solenoid for a good connection, and proper voltage at the starter(10 volts minimum while cranking).
If the starter spins and no crank, the problem is most likely the Solenoid's pinion gear is stuck.
Have someone hit (not too hard) the starter while you try to start the car. This usually works by dislodging a stuck pinion gear.
·Make a simple test of the alternator:
If you can, somehow get the engine running, measure the voltage at the battery. It should be at least 13.6 volts to properly charge the battery.

SOURCE: put in a new starter and car won't start.

Try putting the car in the "on" or "ACC" position for 10 to 15 minutes then turn car off, then turn car on. Doing this some how resets the security on the car. I had this problem today and someone on here told me to do that and it worked.

The security system does not disable the starter, it only disables fuel to the engine. In the fuse block under the hood, locate the STARTER relay. Place your hand on this relay and see if it clicks while someone else turns the key to start...if the relay is ok then the starter itself is faulty. Good luck, i hope this helps.

The PATS security system would prevent the engine from cranking if the system does not "see" the right chip in your key. If the system is working correctly, the light should go off after you turn the key switch on.
You should have power on the small starter wire when the key switch is in the start position.

My Oldsmobile aurora won't start. Battery still


The lights coming on are standard start-up checks.. The most likely issue is corrosion on the battery terminals. Pull them off give them a good clean up and try then. This is the most likely issue failing this it is probably the solenoid on your starter motor.

2003 Aurora, left key on and battery went dead. Recharged battery. Won't start. Turn key to on, security light out and check engine light on. Move key to start and nothing, back to on, one minut


Very interesting site here.. regarding your problem. http://vatspasslockpasskeysecurityhelp.yolasite.com/
Another thought.. even though you charged the battery, it's not at all uncommon for a car battery to be very damaged by fully discharging. Especially if not new-ish. One or more cells in it may be bad causing the overall voltage to be under normal. This alone can cause the problem you have. I would try jumping it with another car or test the battery to see if it's got at least 12.7 to 12.9 volts when sitting doing nothing. Good luck.

1995 Oldsmobile Aurora will start sometimes and other times it won't, I replaced the starter and still the same.


If the engine cranks but won't start, the battery and starter are out of the picture.
When it won't start, someone will need to check fuel pressure and for spark at the plugs to proceed.

I've been having problems trying to start my 96


Is it turning over? If It turns over and starts somedays it may be a extremely easy fix. Just take a wire brush or something similiar and clean off the battery terminals and posts. It will allow clear good connection. :) start with the negative

1995 geo tracker won't start. I've replaced everything except the ignition switch. It used to click when i turn the key, now it won't even click.


DISCONNECT YOUR BATTERY AND RECONNECT, THIS SHOULD RESET THE BRAIN.

ALSO...WHEN YOU TURN THE KEY, LISTEN TO HEAR IF YOU CAN HEAR THE FUEL PUMP COME ON...IF NOT, GUESS WHAT? HOPEFULLY NOT!... BUT,YOU MAY NEED TO REPLACE THE FUEL PUMP, IF YOU CAN'T HEAR IT WHEN YOU TURN THE KEY, AFTER YOU'VE RESET THE BATTERY!

HOPE THIS HELPS!

Hello. My 1997 Chevy Tahoe refuses to start. The problems began with a bad fuel pump. I changed. It worked. The fuel pump died again. I changed it again and it has been working. I parked it for two weeks....


Now you have a good battery & a starter that turns over the motor

Have you cycled the key on & off with a fuel pressure gauge on the
fuel rail?

Do you have a fuel filter that isn't over 3 or 4 years old?

Have you checked for spark while cranking ? Use an old plug on the wires,
if you have ignition wires,don't ground the wire without resistance

If you removed the ducting & MAF Sensor it won't start

Tell us what you checked & exactly how that was done.
