I would check the grounds battery and battery to body and body to headlamp actuator. hope it helps

Security light lit on the insturment cluster ?

No, it has to be programmed by a locksmith to make it work in your vehicle. Call a locksmith and get it cared for so you can drive your toy. About $100 is what I last paid for this service, and I can fix anything. May as well do it ya know.

The key has a security chip in it that has to sync with the computer. dealer can do it or some locksmiths.

Test points for what ? Power and grounds.

You can't do that on your vehicle ! What problem are you having ? Security light lit on the dash ? Lost key ? Probably need ignition lock cylinder , when you stick the key into the lock cylinder there are contacts inside that read the resistor on the side of the key > These contacts wear out , wires break . You can buy a new lock cylinder , if that is the problem or buy a resistor of same value at radio shack an solder it into wire harness . There are videos on youtube on how to do it.

Fuse for transmission pump ? no such thing.

There is no programming or relearn for that vehicle. Unlike some of the newer passlock and passkey systems, your VATS system is not something that can be reset. It either works... or not. You may have a bad key, ignition, or theft deterrent module. You will need to find the failed part or bypass the system entirely. http://www.diy-gm-security.com/ Do It Yourself GM Security bypass

Reves by it's self , that's the PCM/ECM - engine computer controlling the IAC - idle air control valve . Try some injector cleaner ,fuel system cleaner !

there's a gray cable that's gets power from the relay(+) and a blk wire that supply ground!

There is no wire you can cut ,doing this will make your vehicle never start . The Personal Automotive Security System (PASS-Key II?®) is standard equipment on the vehicle. The system is designed to prevent vehicle theft by disabling the engine unless an ignition key with a specific electrical resistance is used in the ignition cylinder. The PASS-Key II?® system and the universal theft deterrent operate separately. The universal theft deterrent system is optional. The PASS-Key II?® system includes the following components: ?€¢ The ignition key

?€¢ The ignition cylinder

?€¢ The body control module (BCM)

?€¢ The starter relay

?€¢ The powertrain control module (PCM)

have to be more specific in your description. Turning over and crank are the same thing....

coil pack module,underneath the coil packs,or you did not replace the ecm with the new motor,you need the computer that goes to that motor

I could be an exhaust leak or it could be the sound of the fuel pump.

Sounds as if you may have burnt out a fusible link. They are usually located in the + side of circuits near the battery or near the starter motor. You can test them with a voltmeter.

Grab it firmly from the bottom and pull up really hard and wrench it side to side. It should start to pop out. Work around the edges until its free. To install work it into place and use a mallet to tap it in.

Double check all your fuses and and wires in connection with your power windows. Unfortunately though pontiacs are notorious for the power window motor regulators to go out, my buddy had 99 firebird and both windows had the same problem, and I previously owned a 98 sunfire and both window motors went out within the same week.

Is the car parked or are you driving it? While its running, what does the battery gauge show? It the meter above or below the midway mark? Its either a bad alternator (or one with bad connection to the battery) or something in the car electrically is causing the battery to drain, like the radio is on even though it may not show itself being on. Good alternator test (although some don't recommend doing it this way) is to start the car and as its running disconnect the battery's ground connection. If the car stalls, you have an alternator problem. Connection or it is bad and needs replacing.

Possible issue with you security module. I think it is linked to your BCM, but I could be wrong. I had the same issue some time ago. After 10 minutes, the car would start. Try getting another key at the dealership. It could be that the chip in your key is starting to go bad.
