Having problems with your 1993 GMC Sierra K1500 ?
How do u set the timing on a 93 gmc sierra 1500 350 ?
You can set the timing but the ecm, engine control module will reset it back to specs. So it useless to try. Good luck dont forget to rate
You have to unplug set timing wire under hood or dash , ecm acts as an advance , 20 degrees back or forward but timing should be placed at spec , if you check timing with wire still plugged in it will jump around due to constant advance or retardation

Is it possible to change the miles on a 1992 GMC Sierra (1500)? I just switched out the v6 with a new 305 and for personal preference I wouldn't mind setting the miles back to 0. Not selling the truck, I mean I could always write down it's current miles to know how many miles are on the engine but it would be nice to set to 0 since its a new engine.
No if you want one with 0 miles you will have to get a new one ... 1992 GMC Sierra

I have a 2004 GMC Sierra 1500 4WD. It will occasionally switch into auto or other 4 wheel drive setting. This normally occurs when I first start the truck. Sometimes it will not switch out of what ever setting it is in, other times after trying to change the setting all lights on the selector switch will go out and it appears to go into 2HI.

I have a 2002 GMC Sierra and my wife has a 2005 Yukon. Odly enough they have both lost specific fan speeds (mine 1+2 and hers just 5) and some of the radio lights no longer work. I was ''lucky enough'' to be in the Sierra when they quit at the same time. all fuses appear to be fine, would the Blower Motor Resistor do this?
The motor blower resistor would cause the loss of the different speeds but not the lights, thats a different issue the speed resistors are not hard to replace and cost's $20.00 bucks for them butthe lights should not be to hard to remove they use the ... 2002 GMC Sierra 1500
I have not been able to get my 92 GMC Sierra radio to work although it appears to have power and will turn on and off. The radio station will appear but volume and tuning controls wont respond. Recently, I had to replace the battery in the truck and although the time and station changed when the battery was reconnected, it showed a different time (1:00) and the station that was programmed to the second button. However, it still wont work. I dont believe its a fuse since there is power to the uni

Rebuilt my 454 engine, installed distributor with rotor at 0 TDC on #1 cylinder. Engine ran fine but ses light was on. Code was P1345-- disagreement between cam sensor and crank sensor. Scanner showed anywhere from 19 to 25 degrees advanced. Rotated dist. shaft. to ****** timing. Wouldn't run. Tried two teeth positions in either direction from original setting. Ever have a sensor go bad. The crank sensor is new, cam (on distributor) is not.
The ignition timing is not adjusted with a timing light or with the engine running, and to set the ignition timing follow these procedures.There is a mark or notch on the distributor housing that the rotor should be pointing to when the e ... 1998 Chevrolet K2500
