Mileage? Since you replaced many parts but not the starter I'm assuming here that you mean the starter cranks the engine but it doesn't try to start up. (If the starter isn't working that's a different issue.)

You need compression, spark, and fuel for the engine to run. First I would do a compression test to verify that the engine is OK internally. Then assuming that checks out you can narrow the problem down to spark or fuel delivery by spraying some starting fluid into the intake and try to start the engine. If it fires up briefly you have spark but if it does not fire up you have an ignition problem. Once you isolate what type of problem you are dealing with you can do more troubleshooting to isolate the defective part(s).

The parts cannon approach is generally not very productive but given the age of the vehicle it's a good bet that at least some of the items you replaced were needed or would be soon.
