There is a possibility that your temperature sending unit for the computer is not working correctly. ( not the sending unit for the gage, there are two). If the computer never knows that the engine warms up, it will keep "choking" and over fueling. Thus, the black spark plugs.

My 1999 GMC Sierra wont start. It has the 5.3l V8


Sounds like a security problem that is preventing starting. It will run for a few seconds and then die.

1999 GMC will crank but will not start.


Check for spark at the coil, if no spark replace it. Also you didn't give size of engine.

I dont understand why you would need that unless you took off all the wires and took out all the plugs and forgot how the wires were.I have the same truck and I always do the plugs and wires one at time to make sure I make a mistake.If this is your ploblem let me know because i might be able to walk you though it.
