Greetings All, My name is Sam I own a 1999 Tahoe LS 4x4 with the 5.7L. My goal is to restore my truck to a super nice condition, and I feel I have a long way to go. My current situation with it i'm having a real pain in the ass ignition problem!!!! I have searched and search the net but found nothing on any forum that fits my problem so here goes..... When I turn the key to the first position I have all my Transmission gear indicator lights on and can move the shifter through each one.....Once I turn the key the next click to start the gear indicator lights go out and I get no crank. I have replaced the following...Neutral safety switch, Ignition Cylinder and housing with new keys, Ignition wiring harness (in the collum) And of course I checked all the fuses and relays. I'm sure I'm going to hear something about the passlock security, my security light is not on, it comes one with all the other lights when I turn the key but goes out as it should. It did this last year but after it sat for a week, the gear indicator came on and it started. I drove it for a while until it did it again, now its stuck like this.....PLEASE HELP!!!!!

You need to read the trouble codes. The Tech 2 is/was the factory code reader. There are also after market clones available.

The Tech-2 was the dealer level scan tool your vehicle was designed to be worked on with. That and a copy of the shop manual's trouble shooting guide and you can get after this quickly and accurately without throwing parts at it and wasting precious time.

Welcome to the Forum from NH.
Lots of knowledgeable folks here who freely share their knowledge, experiences, and perspectives. Knowledge is power.
I hope that you will become a participating member in the Forum's discussions.
Pics of the truck, please.
The folks above are talking about acquiring or borrowing a quality bi-directional scanner. They recommend that you get yourself a quality bi-directional scanner to add to your tool box. Then, you will be able to read ALL trouble codes, along with a brief explanation/pointer to the source of your issue. You will also be able to reset/delete trouble codes, after taking corrective action. You will literally save thousands of dollars in diagnostic and repair costs over the life of your truck, and you will most likely recoup the cost of the scanner within 1 year.
It sounds to me like you will need help from a quality bi-directional scanner to get you over the hump in your troubleshooting. The cost will be ~$350 - $500, depending on which scanner you get.
