when i turn the key nothing lights up on the dash all dead will not turn over my headlights are bright i have parking lights I put in a new starter The van started right up now dead

Check the fuses.

yes i pulled all the fuses under hood and inside

check your battery connections, sounds like a loose ground. check it where it hooks to the block too. makes sure clean and tight.

check the master fuse, look in your repair manuals electrical dims for location...usually under the hood against firewall, then check the connections on the starter if crossed it will draw power and drain the battery

same problem on my 2007 Express 3500 (Start position of key sees no power to dash cluster, no starter cranking or intermittent cranking)..... replaced starter, ignition switch, and NSS but black wire feeding NSS was down to one strand; fixed wiring and cranks/starts just fine. Wiring appeared to be eaten by a rodent. I understand Honda and Toyota have lots of problems with mice eating soy-based insulation on wiring and wonder if Chevy uses same type wiring?.

2007 chevy Express v-6. turn key on and no cluster lights or gauge function but go to start and it starts for a second and all cluster lights come on after it start but goes out when it dies after a second of running. I have checked all fuses and wires and cable connection on battery need help
