    we have a 99 sl2,one day we got gas and it stalled less then a block from the station, had it towed home. Now it runs 15 minutes and just shuts down like someone turns off the key, then if we wait 30-45 minutes it will start again, run another 15 minutes. and so on and so on. We have changed the fuel pump and the fuel filter but it still does the same thing. I'm at the end of my rope, the only code that comes up is p1599 but can not find any anwers. Please help!

    Have you checked the fuel pressure when it quits, do that, then if pressure is ok check for spark at the plugs.

How do I disable the security system to allow the car to start?

A lot of GM cars can be overridden by leaving the ignition turned on for about 10-30 minutes. Be sure to connect a battery charger while doing this so that you do not run the battery down and defeat the purpose. If it does not work after leaving the key on (where the dash lights are on) for 10 minutes, disconnect the battery for a minute and try again for a full 30 minutes (or more). This normally works on the older GM vehicles like yours. Any battery interruptions after this will require you to do it again in the future. Email me if this works for your

My 1999 Hyundai Accent stalls. After few minutes of driving, the car stops and after 15 minutes it re-starts. What is the problem?

When your driving say about 20 or 30 minutes, the car, no matter what, just dies. If the engine cools down, it will start and run just fine, for about another 20 or so minutes, and same thing? Change the coil. its bad, it over heats, and pow. when it cools, works great. Had that happen to me. hope this is the problem

Car sometimes won't start

this is a pass key problem, try this.

1) Put the key in the ignition and turn to the "ON" position. Leave it that way for 10 minutes. After 10 minutes turn the key and take it out. Repeat this process (2) more times (3 times, 30 minutes total) This should reset the passlock system to recognize your key

I'd suggest the ignition control module, however I'd have a certified mechanic check it out just in case...
