84k miles. The starter is turning over, I can hear the fuel pump turning on, I've checked the coils for spark, and all the fuses appeared to be good. The battery is fine, also. Any ideas on what to check next?

 

If you're getting spark, then try to start w/ starter fluid into air intake duct. Try about 5 sec spray.

If no start persists, then spark may be missing, too weak or extremely bad plugs.

If it starts briefly, then fuel is not being delivered. Check fuel pressure.

good luck
