2007 GMC Canyon won't start sometimes, I wait about 10 minutes and it starts. I think its the passlock system. How do I fix this problem?

Sounds to me like the security system failed. I had this happen to my chevy. Check out this page it tells all about it.. You can even install it yourself.. Just look it over I think it could be helpful

Tell the dealer to try a new

The late-90's GM Passlock system (e.g. 1997 Malibu, Regal, Impala, etc.) has a part around the ignition tumbler that goes bad and no longer reliably detects the valid key. In that situation, the "Theft System" light will slowly flash and the carburetor is cut off so the engine won't start. The time-out on the system is 10 minutes - you don't have to do anything, you don't have to disconnect the battery, the key can be out of the ignition -- it's just a time delay. After 10 minutes, the light goes out and you can try again (but if the key is again not detected, the light will start flashing again and you have to wait another 10 minutes)
Someone else, who had this problem, told me to remove all other keys from my keyring. The weight of the other keys pulls on the ignition key causing the key to be unreadable. It has been 7 weeks since I have been doing this and have not had a problem

This car is equipped with Passlock antitheft security by GM. You dont have a chip, but there is a transponder in the key head. This system is known to fail. The fact that the security light is on proves the failure of the Passlock and why it wont run. The hard part is finding out which part of the passlock system has failed. Read this link for info and DO IT YOURSELF solutions to the problem.

Hello:Try this procedure: turn key on, turn to start, let key come back to on wait ten minutes, turn key off wait 10 seconds turn key back on wait 10 minutes. turn key off wait 10 seconds turn key back on wait 10 minutes turn key off wait 10 seconds NOW try and start. In addition you might try tapping on switch assembly while trying to start. There is not any way to disable passlock. You might try having the engine control system codes read

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/

check security system have you used different key or are you trying to use a old key that hasn't been used for long 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.

sell the truck and get one that does not have the security system that locks out the engine starting. I wish I could but I can't for a year or so.
