I have a 96 Z28 5.7 LT1, My son was driving it, going about 20 MPH and it stalled and would not restart. Put the OBD 2 scanner on it and read Throttle Position Sensor low voltage and Bank 2 Sensor 1 faults. Installed new TPS sensor and still cranks but will not start, Fuel pressure is good and has spark. I have not installed the new O2 sensor yet, Will the o2 sensor cause it not to start? I dont think so, if anyone has a clue please reply, Thanks.
