I rebuilt a 2002 and it fired right up...no ignition timing needed, but im no mechanic...that same truck is forgetting the key occasionally and I have to train the key to the truck for ten minutes before it knows it not being stolen and will allow it to run. After u attempt to start the truck leave the key in the on position and if the diagnostic screen on the dash flashes the security light at u then back to the battery light leave it on for ten minutes until the security light is no longer flashing then turn off and retry...sometimes it has taken two to three times of doing that then all the sudden it will fire right up and no problems untill that sob forgets again...have no idea what keeps cusing this to mine... good luck maybe this will help u

#749 of 769 Fix for Silverado Electrical "Gremlin" by dbvz

Feb 08, 2013 (9:58 am)

Has anyone resolved the electrical "Gremlin" as described in post #556? I have experienced this and it is quite frightening while driving. Called my local dealership and he said he had never heard of anything like that happening. Don't want to waste a bunch of money there if they have no idea what is going on. Seriously considering a trip to my local Ford dealership for a trade. What a shame, I really like my Silverado.

There was a guy on here that documented similar problems on youtube and it was scary. He apparently got some deal from GM and the youtube video was erased. MY GM truck lost brakes early in life due to brake lines that rotted out in less than 4 years. Endless warranty issues and I was nearly always greeted with the "deer in the headlights" look at my dealer, but at least they fixed at 1-3 warranty items at nearly every oil change ( several repeats in 3 years) . I know of many accounts of the early failing brakes, and in fact it was investigated by NHTSA, only to see the case suddenly closed. GM Customer Service kindly contacted me on this board, only to tell me, 'sorry, we know nothing about those brake line that burst early in life' (many accounts on the internet though). After 35 years, I bought a Ford. You will be glad you did. Had a warranty issue, no deer in the headlights look, they just fixed it.

I had the same issue with my "07 Silverado 1500 as well a couple months ago. It reminded me of a cold start on an old pickup. I had to attempt to turn the engine 3 times for it to start. I knew it was not a battery/alternator issue because I had power, but it just did not want to turn over. I told my husband about it and he did not seem concerned as it has never happened before or since, but there are many other issues with this truck that I have experienced and have read about on this forum. It almost seems worth it to look into trading it in before it goes kaput on me.

Sarah,
 
Can you please assist me, as well? I am having the same issues with the ABS and Parking Brake lights on my 2000 Silverado 1500, 5.3L V-8 Z71. It has 181,000 miles on it. I can email you the VIN. Thanks so much!

#753 of 769 minor electrical/transmission issue by sarahc7

Feb 13, 2013 (2:32 pm)

I have read in the forum about other owners having the shifting issue and the bump after braking. Has anyone found or recieved a resolution to those? My shifting issue has come up very recently and it is during upshift instead of down shift. It is not really a slip, but more of it putting itself in neutral. The bump does not bother me, but it concerns me if is something that needs to be replaced as mentioned before about a selanoid or some time of slip yoke(?).
Also, I have experienced an issue with my interior electrical system that coincides with the weather. I have been told to check the fuses, but honestly I have yet to do so as I cannot locate the fuse box in the new vehicles ( I am used to the old fords). Anyway, the speakers fade in and out during good weather and will alternate between front and back. However, if it is below 65 degrees or raining, only one speaker works. I have tried adjusting the settings on the radio, turning off bass, raising/lowering treble, going between F/B and L/R, etc. Those appear to have no affect on whether or not they will work. On a good weather day, they work fine. This is minor and trivial, however it does affect the turn signal sound. I have checked to make sure they work, and they do. So, at this point I am stumped. I luckily have not had any problems with my indicator lights, tachometer, speedometer, locks, or any of the other ghost electrical problems, but am curious to know whether the poster that had the ground issue under the seat had anything similar going on before he resolved his ghost problems. Oddly enough, I had a 2008 Cobalt that had the same interior electrical issue as this truck. I was never able to have it looked at or resolved, as it was totalled in 2011. I had previously wondered if it was a issue with condensation getting in the wiring harness or connections. If anyone has any ideas or input, I would love to speak with you.

If you haven't already, send your information over and we can take a look. However, given the age and mileage of the vehicle, I cannot guarantee we'll be able to assist.

Thanks Sarah. I am going to try adding some fluid to transmission it was a bit low. I want to see if that will help the slipping, but I don't know about anything else. I will let you know though if we do. Thanks again.

#757 of 769 2001 GMC Sierra 1500 Climate Control by chevyatic

Feb 20, 2013 (11:05 am)

If I am driving with the heater on I can't adjust the temperature it stays hot, if I switch it over to A/C it won't change unless I kill the truck and restart then 90% of the time it will go to A/C, but it won't go back to heat unless I do the same of killing the truck and then restarting? Where do I begin my search for a cure?
