2003 Saturn L200 2.2L No Start, Cuts out, erratic guage readin VIN: 1G8JU54F43
Reprogamming the BCM using a Tech II fixed the problem. Adam's response made the most sense. I also noticed the BCM wasn't reading the complete 4 digits of the SDM. All's well with the vehicle. I drove approx. 20 miles and, at different times, left car idling.... Trouble codes: U1000 (Class II serial data link malfunction), U1088 (Lost Com. with SDM), U1016 (Lost Com. with ECM), P1631 (Theft deterent fuel enable signal not correct), P1599 (Engine stall detected).
