Odd no start issue
This is not your typical no start thread, i belive the issue is with the lock cylinder or the anti-theft / ignition module
Sometimes the the cylinder wont turn with the key.. and when it does every once in a while it starts like normal, other times when I put the key in the run position... the check engine light will be on faintly (if i press the brake pedal it gets brighter) and as well the fuel gauge will not read the amount of fuel in the tank it sits on empty and the low fuel light is on, when the dash displays like this when I move the key to the start position it does not start, and the dash goes blank once releasing from the start postion the lights return to the dash however they will get brighter then dimmer the brighter then dimmer even after repeated attempts it can stay like this for a bit, other times it will start like normal
I got new keys made at the dealership from the vin, but that made no difference
any help would be appericated
Thanks in advance06 Z71 Silverado Military Style!!!

You may have 2 problems in the same area.
Problem #1 is a worn locking mechanism. You need a new locking cylinder. You can purchase a new cylinder from a dealer and them take it to a locksmith to have the pins changed to match your key. Your truck uses one of the GM PASLOCK systems, I don't recall which one, therefore, you may also receive a new key with the cylinder. The new key (if one comes with the cylinder) can be cut to match the cuts on the old key. If a new key blank comes with the cylinder, using the old keys may trip the security system.
Problem #2, may be a worn ignition switch. The switch is not part of the ignition key cylinder assembly, it is connected to the cylinder with a rod and it is mounted lower on the steering column. The switch may not need to be replaced, all of the wear may be in the cylinder/rod assembly.Ray

From what I gather from your post is that the issue could be with the cylinder where the key itself goes in, and/or the rod that connects the cylinder to the ignition switch.
Is there any further diagnoises steps that could help narrow down the fault
does any one have access to mitchell with the procedures on replacing these components

you may have ignition switch linkage problems as well . If the locksmith looks at this issue he maybe able to fix it or instruct you as to why its messed up if his work will not correct the voltage/crank issues with starter ..
I would have the battery load tested and the connections cleaned .
I would be surprised if the lock cylinder was worn out unless your key got chewed up and you continued to use the worn beat up key. perhaps a theft damage ?
