need some advice and/or direction please. I’ve got a 99 express w/5.7 130,000 original miles. Everything was working fine till “BAM” last Thursday when I get in to go to lunch. Turn key on and nothing!!!! Want crank & I’ve got no DRL, no fuel pump kicking on, no blinkers or instrument panel lights or gauges. Checked all fuses… GOOD, starter/fuel pump relays are good. Battery has 12.9V & terminals/connections are good & clean. Only thing I’m aware of where all those different problems have in common is the ignition switch or computer maybe??? Any good ideas/help would be greatly appreciated!!!

Do not post duplicates please.

I suggested 3 days ago to check your ignition switch.

You'll need a wiring diagram and a multimeter or test lamp.

ok I replaced ignition switch and still have nothing, same as before no crank no start? Any other avenues I can try?

Do you have a "wiring diagram and a multimeter or test lamp"?

Don’t have the diagram but have a multimeter.

Having a multimeter but no wiring diagram is like having a compass but no map. You need the diagram.

That's a great video on following a diagram.
