wont start

No, a bad ignition module would not do this. It sounds like you may have 2 problems in that if the fuel pump is defective, it would not cause the dash lights not to work and vice versa. I would definitely check all the fuses, then I would check for power and ground to the fuel pump while the engine is cranking. ( you have to have the engine cranking for the computer to turn on the fuel pump ) Do you have spark while you crank the engine? here are some shops if you need more help: https://repairpal.com/gmc-repair-in-roanoke-virginia
