Malibu won't start

I have a 2001 Malibu with a V-6. Yesterday my wife went to the video store to return a video. When she came out and tried to start the car, all it would is crank over as if you had no spark so she had it towed home. I checked and it seamed to have fuel pressure in the fuel rail. About 8 hours later I got a chance to look at it. I cranked it over and it started up just like nothing happened then I remembered something the prior owner had mentioned. He said that they had a problem one time that the car wouldn’t start so he replaced the fuel pump and some other things before he found out that it had something to with the security system or something along that line and all he had to do was to try to start the car or to remove the key “X” amount of times (I can’t remember exactly what he said) So my question is has anyone heard of this problem and know the procedure to start it if it happens again?
Now I’m kind of afraid to have her drive the car and get stuck somewhere.

If I were you I call a dealer they would be able to tell you if it is a factory security system. If call who ever made/installed it.

Yes it's the factory system that all GM cars come with nowdays and I called the Dealer and all they want to do is connect it to the computer to ckeck the codes for $200.

If it is the Passlock system giving issues, the engine will crank, fire and run for about 1.5 seconds, then shut off. The theft light on the instrument cluster will then begin to flash. You may have to go through a "re-learn" to solve your issue. Turn the key to the on position, and look to see if the Theft light is flashing. If so, leave the vehicle for about 20 minutes, (key on) and it should re-learn the security. Sometimes this takes a few attempts. Also, chec to see if the lock cylinder feels "loose" in the housing, if it is, the air gap at the Passlock sensor may be intermittently too large, ad not allowing the signal to be read.

Turn OFF the ignition, and wait 5 seconds .
Repeat steps 1 through 4 two more times for a total of 3 cycles/30 minutes (the vehicle is now ready to relearn the Passlock Sensor Data Code and/or passwords on the next ignition switch transition from OFF to CRANK). IMPORTANT: The vehicle learns the Passlock Sensor Data Code and/or password on the next ignition switch transition from OFF to CRANK. You must turn the ignition OFF before attempting to start the vehicle.
Start the engine (the vehicle has now learned the Passlock Sensor Data Code and/or password).
With a scan tool, clear any DTCs if needed (history DTCs will self clear after 100 ignition cycles).


If the engine does not fire at all, I'd definitely take it to a reputable shop to have it checked. The days of the rule of thumb are over, and diagnosis requires a scan tool. $200 for a simple code read is ludicrous, I'd look at a different dealer.

The wife said it just cranked like she was out of gas and when I got there I tried to start it and it just cranked & cranked. I didn't notice anything flashing on the dash. I guess I'll have to wait and if it ever happens again (hope it never does) I'll have to look closely at the instrument panel.

Don't think it's vaper lock as the first thing I did when I got there (after cranking it over) was to check the fuel pressure by releasing the shrader valve and a lot of fuel shot out. I didn't have any kind of pressure gauge with me but it seamed like a lot of pressure. I realize it probaby takes 20 lbs or so to activate the injectors so it's possably that it could be vaper lock, but vaper isn't so common nowdays. Also I didn't get a chance to see if I had any spark which is another possibility.

KOEO pressure is 52-58 psi, so 20 wouldn't even fire. I would try to recreate the scenario, and have a fuel injection pressure guage on the schrader to see if the pressure begins to fall off, as well as a scan tool hooked up to look at the fuel trim values.

That's most likely what I'll do. These code scanners that they sell in Kragen & Autozone for about $100 on sale, do you think they scan that type of codes or are they only for emissions codes?
