Have a 2001 GT with the series2 3800 that has manifested a weird problem. I replaced the power steering rack, and after re-assembling everything the car will not start, and the electrical system acts very weird. The security Light, driver information center, and dash lights, flash very quickly in synch with the bell. Started fine before, and have looked all over to see if I pinched any wires, and can find nothing. Only other thing I have done is to install a new mass airflow sensor. Any Ideas?
