Hello Im new here, I hadn't realized you all had migrated over from Trailvoy. I posted this over there but It seemed like it was getting stale so if its ok, I've copied and pasted it here.
My 2006 Trailblazer 4.2 L won't crank/start. The car is driven regularly. Some unusual symptoms:
1. Cannot crank the starter with key....Battery directly to the solenoid will crank (but not start) the engine.
2. Cannot establish a link with the PCM using my my code reader, after scanning for some time it says NO LINK or something to that effect. The code reader worked just the other day however.
3. With the key in RUN position, (or any position for that matter), the horizontal indicator line under P-R-N-D-2-1 dash display is not illuminated at all (i.e. the transmission can be shifted to any gear, but there is no indicator line beneath the display to show what gear it is in).
4. With the key in RUN the reverse lights do NOT illuminate in any transmission position. HOWEVER..The reverse lights DO turn on when the key FOB button is pushed (as it normally does for providing illumination while unloading).
5. In the engine compartment fuse block, I can verify correct operation of the Starter relay [47], and the adjacent Powertrain relay [57]. (to clarify, I pulled them out and checked that they function correctly...not connected to vehicle) I also checked most of the fuses. Also, Checked most of the fuses in the rear underseat fuse block.
The battery is not in excellent shape but it had no problem cranking the engine when I jumped directly to the starter solenoid. Ive had it on 2Amp charge all day to make sure I could run thru all the tests without running it down.
I Replaced the ignition switch in the hope that it would fix the problem after reading thru Trailvoy comments, but the problem is unchanged. I assume I set the teeth correctly....The key moves thru ACCY, RUN, and bounces back from the START position.
After hooking up the battery after changing the ignition switch, I went through the extended PASSLOCK relearn procedure, as descibed somewhere in this forum. It did not do anything. (The first time I tried it, I accidently left the lights on during the procedure and ran the battery down. Its been on 2 amp charge since then)
I looked at the transmission position indicator switch, it does not appear to be damaged, I might remove it to inspect it more closely.
Yesterday we had an electrical storm, and there was a real loud strike from the direction of the driveway where the vehicle was parked. However, I have found no physical evidence whatsoever of a ground strike near the vehicle.
This is my wife's vehicle, and she needs it for work tomorrow!
UPDATE. Since I wrote the above, I realize the lightning strike did cause damage to a 16-inch Oak which is about 75 ft away from where the truck was parked. Blew off a strip of bark from near the crown all the way to ground, the followed a root, blowing the soil out of the ground. However, its pretty far from the vehicle, and the root it followed along the ground went away from the vehicle.
