Do you mean interior light comes on , if so one of the door switches are not being depressed to shut of light this may include rear hatch door switch also , open one door at a time and depress switch with finger if light goes out try next door , also if light has been on you may have flat battery check charge first.

SOURCE: I have a VERY intermitent/passlock - no start

Common for the ignition lock switch it self has gone bad and will need to be replaced. This is more common if you have lots of keys on your your key chain, the extra weigh wear out the electrical sleeves in the cylinder walls making the passlock not to read the proper resistor reading on your ignition keys and needs to be reset all the time. My In-Laws had the same problem with there Grans Am and was at the deal once a year for it. Once the warranty ended I got the passlock 2 by pass for around $70.00. The factor alarm still works but the ignition immobilize was disabled so they would not get stranded out in the cold. Here is the link and good luck, keep me posted and it's just a plug and play so there is not wire cutting and splicing. Keep me posted and don't forget the rate. http://www.gmpasslock.com/

Passlock is the anti theft that is built into your car from GM. If the car is not stalling while driving or having starting issues, it is probably not a problem. It might just be an informative light. If it ends up making your car die or not start, it is a passlock failure which can be expensive.

Truck wont crank each time

It sounds to me like that you have several different issues with you vech and on the pass lock system will not cause all the problems listed how ever it will cause the no crank and after five min or 30 min start it is most likely the pass lock sensor unless your truck has a pk3 system (the key will have a + or pk3 stamped on it)If it is a pk3 system then it may be the theft detturent module if ton a pk3 system then most likely a pass lock sensor . Take the vech to some one that can ck for codes and find out all the codes set in the vech. This will tell a whole lot about what is going on with the vech .Im not very good on drivabilty problems. The evap leak and the mis fire will not be related to the pass lock problem.

i had the same problem on my 98 sonoma. for some reason your passlock system did not recognise your key and went into security. you have to take it to a dealer or a shop with a computer and have them reset your passlock. if you have a buddy or know someone with a scan tool they may be able to do it to. i think the shop here charged $35. but there is no other way to fix it.

sounds like your passlock sensor on the ignition barrel is faulty. you will have to go to the dealer to have it replaced because of the programming after replacement.

1994 gmc safari

Sounds like your Passlock security system went into the tamper mode. If your dashboard security light blinks when the ignition is turned on, your Passlock security system is disabling the injector module, preventing the car from start. Try this:
1- turn the ignition on and just touch the starter, without getting the motor to fire, then leave the ignition in the "on" position. The security light will blink for about 10 minutes. When the light stops blinking, turn the ignition off and leave off for 3 minutes.
2-repeat the step #1, 3 or 4 times. You will know that is fixed when you turn the ignition on and the security light does not blink, then the car will start. Make sure to stay inside the car when you're doing this, as opening the doors will trip the security tamper mode on again. Once the tamper mode is off, the car starts and opening the doors will not trip the Passlock tamper mode.
