On Saturday I bought a 2001 Malibu to have as a work car. The guy I bought it from had the car for 14 years. He had all repair records and even had the Carfax. While looking at the car and test driving it, I probably started it 3 or 4 times. always started right up. I drove it home and it sat in the driveway until this morning when I was going to get the title and plates. Went out and it won't start. It turns over but won't start. Did some research and read about the common problem of the anti theft system. As I had started the car with both keys I thought this could potentially be the problem. All the posts about it talk about the "theft system" light blinking. Mine is not blinking it is on solid with the key in the on position and goes out when trying to start. Still, I went through all the reset procedures with no luck. Could my luck be so bad that right when I parked it in my driveway the fuel pump went out or something else major? please help!

All "crank, no start" conditions are approached in the same way. Every engine requires certain functions to be able to run. Some of these functions rely on specific components to work and some components are part of more than one function so it is important to see the whole picture to be able to conclude anything about what may have failed. Also, these functions can ONLY be tested during the failure. Any other time and they will simply test good because the problem isn't present at the moment.
If you approach this in any other way, you are merely guessing and that only serves to replace unnecessary parts and wastes money.
Every engine requires spark, fuel and compression to run. That's what we have to look for.
These are the basics that need to be tested and will give us the info required to isolate a cause.
1) Test for spark at the plug end of the wire using a spark tester. If none found, check for power supply on the + terminal of the coil with the key on.
2) Test for injector pulse using a small bulb called a noid light. If none found, check for power supply at one side of the injector with the key on.
3) Use a fuel pressure gauge to test for correct fuel pressure, also noticing if the pressure holds when key is shut off.
4) If all of these things check good, then you would need to do a complete compression test.
Once you have determined which of these functions has dropped out,
you will know which system is having the problem.
