AC belt sliced the oil cooler line. I pulled over when I saw the pressure drop but may have been too late. I bought a new cooler line and had it running in the garage. I drove out to go around the block and it died. I can't get it to crank. Tried a jump and tried to make sure vaccuum lines were back in place (at least one was pulled apart near the oil filter when I was dismantling the old cooler line).

I've got it on the street tonight and will start calling around tomorrow for help, but I'm sure it's pretty bad. Body is fairly good and all electronics work amazingly well, but I can't sink thousands into this vehicle. I suppose I need confirmation, but assuming the worst, any ideas about what I should do?

Greasecar kit is installed and working (it died on vegetable oil, which is maybe the way it wanted to go). Thanks to forum members for all the help in determining the other problems I've fixed in the car (new alternator and neutral safety switch).
