check for volts at the wires on the starter while someone is turning the key to start, go from there. And check for volts at the relay while someone is turning the key to start, go from there.

He has verified voltage at the starter solenoid and has tried jumping the small to big terminal. This eliminates everything before the starter in the starting system.
The only thing not conclusive here is ground to the starter, which is pretty rare since it's bolted to the block, just like the negative terminal from the battery.
Before condemning the starter. It may be the big starter wire. If it's corroded or has broken strands in it. There will be 12 volts, enough to make a multi meter read 12v or a brighten up a test light, but not enough current to engage a solenoid and spin the armature.
Or ya, the starter is bad.

I just went thru this myself. from your descrip (what you jumped/amount of sparks) the starter IS bad.

East to test.Test light to ground.Should have power all the time to large lug.Move to small terminal.Use key if test litgh lights power is there.Should crank.You can also make sure terminals are tight.Then tap starter with a hammer and many times they will start.Oh yeah just because the ends on cables look clean that cable itself can be bad inside.Ive seen many that were corroded inside.That and make sure battery has good voltage.Ive seen batterys that will spark but say with lights on and cranking they dont have enough juice.Rocky

Is the bendix engaging when you turn the key? Does it engage when you jump across the posts on the starter relay? Any click-click sound? If no sound of the bendix engaging it could be the bendix is shot, the starter relay is shot (bypass it to find out) or no juice getting to it, to engage the starter teeth to the ring gear. If it is engaging the bendix then the contacts in the bendix that feed juice to the windings to energize the stator and spin the starter motor could be corroded/pitted/worn out, the brushes could be used up/chewed up and / or there's a short due to brush dust accumulated. Starters are DC motors and pretty simple to tear into. I've polished the stator contacts, washed the brush dust out of a few and cleaned/sanded/filed the bendix contacts on more than one to it going. They can be bench tested by clamping it into a bench vise, and hooking jumper cables to it. Positive to the + on the battery and the stud the heavy red wire bolts to. Negative to the - on the battery and to a mounting ear on the case. A bump switch, used to bump a motor over when setting valve lash, between the wire posts on the starter, or even a screwdriver...
