Hello and welcome. My name is ***** ***** you for visiting the site, I am reviewing your question and will reply shortly, thanks.
Do you hear the fuel pump come on for 2 seconds when the key is first turned on?
Do you know what the fuel pressure is?
How did you reset the passkey system?
I see, thanks. Did the security light go off after the 10 minutes?
It will if it goes very close to dead. Can you read the trouble codes to see if there are any VTD system codes?
I see, you may want to keep a charger on it while doing the Passkey relearn on it. Let me post a link to the factory instructions, thanks
Did that work?
That shouldn't matter with the Passkey sensor, it doesn't need a key fob in order to work. Let me see if I have any tests for the VTD system.
I do have the test for, "Security Indicator Always On Or Flashing" which does require a scan tool.
Actually a good scanner that is comparable to the Tech 2 used by GM is very expensive and it doesn't pay to buy on unless you are in the business. Just for the sake of software and application hangups, did you try taking the negative battery cable off for about 10 minutes of so to maybe clear out any problems?
