sounds like weak battery

Does the security light stay on or come on for a buld check and then go off?
Check start fuze and relay and neutral saftey switch and for start signal from ign switch.
Any remote start or anti theft stuff?

No remote start... Turn key to start position lights go out and radio digits go out. If I jump at starter vehicle will run and stay running until I turn off ignition key. If I try to start from key again it will not start.

About a month or so ago we purchased a spare key from Home Depot could this be the problem possibly with the theft system>

Update on my wife's 2004 Chevy Malibu Classic there is no power to starter. Mechanic friend thinks it could be short to starter from ignition and/or ignition switch is bad. Any advice?

I have a '99 malibu and I've been using a spare key that was made at an Ace Hardware store for the last couple of years. There were a couple of times that the Theft light came on and I couldn't start the car. After waiting 15 minutes, I was able to get it started. Also, there were times that when I would be driving and the light would come on by itself. After getting to where I needed to go, I would turn the engine off then restart with no problem, and the light was gone. A few weeks ago, this would happen more and more frequently until I couldn't start the car at all. I let the car sit for a while then decided to try one of my original keys. The car started up every time until I went to use the duplicate key from Ace. For the last 2 weeks, I haven't had a problem with starting or having the light come on when driving.

I had a problem similar to you except I did not use a new key. The theft light came on and the car would not start. After trying to reset the system with key on and waiting for light to go off I sprayed WD40 in ignition cylinder and so far have not had another instance of this happening

If you have the resistor pellet in the key system.
You can test the pellet with a volt/ohm meter for the correct restiance.
The ohm resistance of duplacte key should match unused or a new origional that has not been used much.
It is always best to have the dealer make a duplicate key with his matching machine.

Also carrying the key in your pocket can wear off the pellet and lower the pellet resistance.

I have a 02 Malibu,

If I use the PLJX from here "http://www.passlock2.com/", can I by pass the theft system without cutting any wires?

I tried to download a manual for PLJX, but can't figure out how to install it

Thanks advance for your suggestions!

I have a 98 Isuzu Hombre, that will not start. Turns over but doesn't crank. Could this be the problem? It has new fuel pump and new ignition coil packs, everything seems good but will not crank.

Does the security light come on key on and then go off?

I bought the truck used, guy said he went to start it and it wouldn't crank. He thought it was timing belt. I tore it down found it was timing chain not belt and in time. I went ahead and put new timing chain tensioner and gears while it was apart. Tried to crank it before putting everything back on turned over for along time with me resting the starter and finally cranked. Put it back together and hasn't cranked since, about 18 months. But I noticed the security light stays on. I mostly work on older cars so didn't mean alot to me. Started searching after trying everything else mechanics told me try, I have a ton of new parts on it now, maybe this was all it was all along.

Security light comes on then goes off, when you try to crank it, it comes back on and stays on.

Light should come on for a bulb and go out when key is turned on.
Does it start and run a couple seconds then dye or just not start at all?

Have you tryed the auto learn procedure by turning key on and bump starter and then leave key on 10 minutes untill light goes out and then off and on for another 10 minutes untill light goes out.
Repeat 3 times and see if it will start?
Post back results.
