Well I got the 86 going and did a little light test drive it was doing OK with old gas and the like and had been resurrected after many years of sitting. I was doing about 20mph just driving around my neighborhood taking it easy on it when it suddenly sputtered and died. I walked to a friends house we came back and jumped it cause I had a weak battery in it and it didn't fire at all not even a pop.

Kept trying to start it and then the motor started turning fast like it had no plugs in it at all while trying to start it. Like just then it lost all compression. I pulled it back home and parked it.

Any ideas? Broken timing belt? Clogged fuel filter? Loose plugs? Any idea why it would suddenly start turning over very fast under starter power like it had no compression? Blown head? Weird! Doesn't make sense that all the rings could go bad at once. If the timing belt broke would it spin fast under the starter load? I had oil pressure and it was running at the correct temp.

Any help would be greatly appreciated. Thanks
