Electrical problem
1999 Chevy Astro 6 cyl Two Wheel Drive Automatic 122000 miles

started missing about 6 months ago. Changed out wires rotor and cap didnt get better. Went and changed out the plugs. Was better for a little while the the same. Then driving home it died. Started up again went a mile then died. Replaced the fuel filter still wont start. Replaced the coil and the module. Still no fire.

Quick throwing parts at it do below

Lets do below for a start to determine if its fuel or spark related issue and get back with some results

Get a helper disconnect a sparkplug wire or 2 and ground it to the engine atleast 3/16 away from ground-have helper crank engine over-do you have a snapping blue spark? If so-you have a fuel related problem, check the fuel pressure to rule out the fuel filter/fuel pump/pressure regulator and listen to the injector/s are they pulsing or hook up a noid light. No snapping blue spark continue to troubleshoot the ignition system-power input to the coil/coil packs, coil's resistances, distributor pick-up coil, ignition control module, cam and crank sensors and computer Note: If it doesn't apply disregard it
