Canged The Alternator And Fix The Ground Cable. Now It Looks Like Every Cold Spell The Comes By My Truck Will Sit There And Crank But Never Start. Then It Will Start Like If Nothing Has Happen. I Do Not Know What Is Going On But I Need To Fix My Truck And Do Not Have A Clue Where To Start From... The Battery Is Good, Fuses Are Good, Removed The Power For The E- Fans And Still Does The Same Thing...

Please Help If You Could Give Me Some Tips On What To Look For... I What To Use The Gm Shop For The Last Resort... I Located In The Gaveston Area Right Now If You Know Of Any Good Shop The Could Help With The Problem...

Sounds like a loose wire or fuse connection. Go back through everything you messed with and look at the connections, then look at your fuses to make sure the connections didn't overheat causing the prongs to come loose with movement. This happened to me with my fuel relay so I put one ecxternal to the main fuse block. Just some thoughts.

That May Be Right Because I Did Get One Fuse Out The Was In Pertty Bad Shape. I Will Take A Good Look At The Connections And Fuse Connections. I Did Have A Sleve Over The Fuse So I Might Have Made It To Big Now The I Do Not Have The Sleve On There. Thanks I Need To Get My Truck Running, Now That I Have More Day Light When I Get Off Of Work...

Good luck!

I Have Not Had Time To Take A Good Look A The Truck But I Sure Hope The Problem Stay Simple... I Can Not Contine Doing Any More Mods Until I Solve This Problem... This Bring My Truck From A Dependable Truck To A Undependable One... Well I Got To Get Off One Day Just Detail All The Wiring And Fuses That I Messed With...

Thanks...

I Found The Problem With My Truck... The Ign. Key Is Going Out... I Do Not Know How Much Longer It Will Last But When The Key Is In The Start Position I Start To Release The Key And It Will Fire Up Every Time... I Looks To Be Getting Worse Because It Was On Acting Up In Cold Weater But Now It Looks Like Every Morning... I Guess I Will Have To Take It To The Gm Shop To Change Out The Ign. Key... I Have One Question Before I Do That... I'm Truck Has 120,500 Miles + Or - But The Dash Gages That I Replaced It With Show 70,500 Miles... Will I Get Burned For This Or Should I Go To A Local Shop.

Did you just say you changed the dash cluster?

Did the problems start soon after that?

Check everywhere for bad grounds. They will play havoc with an electrical syst. All your starting goes through the PCM and BCM so look at body grounds also.

There is a sensor in/near the ignition lock cyl that could be going bad or just need to be programmed, I think that when you change out the cluster you have to reprogram the theft syst.

I don't see where anyone would be concerned about the mileage difference at this point. You're not under warranty.? If you sell the truck then yes you must disclose the correct total mileage. If you worried about the mileage then ask if the tech can correct it if they have to reprogram the BCM or IPC. I know they can do that to a new cluster.
