Car turns over but won’t start. Battery light and check engine light is on.

What is your question?

My car turns over fine but won’t start. Last time this happened it was corrosion on the distributor rotor. I didn’t change the rotor then so this time I changed the rotor and cap and it started and ran perfectly. Then after sitting in my garage for a weekend it wouldn’t start again just the same as before. I double checked to see if a coil wire was loose and nothing is. Nothing else has changed since starting my van fine on friday. The check engine light and battery light is on, could this possibly mean the battery has enough juice to turn over but not spark? (The spark plugs were recently changed too)

How long has your 2001 Chevrolet Astro had this problem?

Since I discovered it on monday morning (2/11)
