crazy car

Daughter ran car hot.
Ran but no power, lurchy.
Would not re-crank. Unplug MAI sensor and cranks. Idles great, Touch gas, dies. Tried (2) new MAIs. Now won't crank at all, even when MAI is unplugged.
Next day, cranks fine. Its location was terrible, reversed out of bad spot, drove to a better spot. Will not restart. Ran rough, no power, lurchy while it ran as before.
New plugs and wires. No start.
New coil pack and module. Now starts, but very weak idle. Runs about 3 minutes, dies, but restarts. Can't give any gas.
Compression, 120 on 5cyl and 90 on 1. Gas rail pressure good. Sucks air great.
Unhooked exhaust, no change. Got fire,got gas, got air all the way through.
2 relays in fuse panel. Switched them, won't start. Switched them back, starts.
Whats up with this crazy car? :banghead:
Thanks, btw, not a mechanic

1989 Olds 98

3.8 not supercharged
reg 1990, door seal 1989
engine vin code C

Ok, removed harmonic and found twine entangled in fins and crank sensor broken. Replaced sensor.
Now starts, very low idle, rough and sounds like a choo-choo. Give gas, dies with a blow back out the intake. Cranks right back up. Heard a vaccum bleed down after dying. Found a cracked elbow on vaccum line. Fixed that, no change.
It is a 1990, from 8/1989. 98 Regency. 3.8L, no supercharger.
New crank sensor, coil pack and module, plugs and wires, so far. It has gone from not starting to starting, very low rough idle, dies with gas.
