I have a 2000 GMC Sierra and all of a sudden it starts and shuts off after about 10 seconds. I've changed the fuel pump, fuel filter, crank shaft sensor, throttle body sensor, and a couple of others

Get the code or codes reed most likely will tell you exactly what is causing your problem. Parts stores like advanced auto or auto zone will read the code or codes at no charge.

Just worked on a 1998 GMC Sierra that was doing the same thing got the codes reed and it was the camshaft sensor not saying that is your problem or you may have replaced the camshaft sensor already. Point is code told me what was wrong and it fixed the problem.

I have a code reader and it is coming with the following codes...U1000, U1016, U1041, U1096 and U1064

Going by all of the codes I am reading you need to take vehicle to dealer to get the Control Module updated. Found a article on line about getting all of those codes at one time. Go to this web site.www.justanswer.com/fm/7bhbz -does-doc-u1016-loss-class- communication-vcm.html#re.v/379/

All of the codes are saying there is a communication problem with your vehicle to the PCM.
