After messing around with it for awhile, he plugged it in to his machine and determined that it may have to do with the crank sensor. We unplugged the crank sensor and it finally turned over. It was still a little difficult to turnover though. I got it home and bought a new sensor at the dealership. I installed the sensor and plugged it back in (it had been off because it was the only way of getting it to start). There was no improvement... I have since unplugged it and am supposed to go see another mechanic. As a sidenote: my VDC, Slip, and Service Engine Soon lights all came on. I reset the ECU with the ignition/gas pedal way and drove it around for a bit, but when I parked it and restarted it, the lights all came back on. You may be thinking "if it starts then just drive it without the sensor plugged in"... The problem with that is that it will not always start, it usually will but not always. I am beginning to wonder if the flywheel has something to do with it. This is driving me completely insane! Please, please provide any insight that you may have. Thanks!

What I'm wondering though, is if they determine the aftermarket flywheel to be the cause; am I responsible for all of labor costs incurred for diagnostics? I'm sure I would be responsible for the labor costs to fix it, but I'm just wondering about the cost of diagnostic.
