Okay, I'm new here and need help. I have a 2002 gmc sierra 1500 with a 4.8l vortec. The other day my truck suddenly wasnt getting fuel and wouldnt start. Stopped and thought bout it and 5 minutes later it started. Drove it home 2 hours and then no more start. I changed the fuel pump with one out of a parts truck and nothing. SO. There is no power to my fuel pump relay under the hood. However i noticed that my 20amp primer fuse next to it was blown. Changed that and tried the truck. Blew the 20 amp fuse again. The truck will turn over with starter fluid (I know its not good for it), so i know it has to be the fuel issue. I thought about changing my entire ignition however I dont really want too. So i Could really use some help, im sure this has happened to someone...

Ive also reset my Computer, and the truck is throwing no codes
