Asked on May 5, 2012

Will an OBD2 scanner work on a 1994 bonneville which is probably OBD1

My bonne will not start. Check engine light on. connected OBD2 scanner but it did not read out codes. I have 42 lbs fuel pressure, but bonne acts as if it is not getting fuel. Checked fuel injector harness, have power but no pulse. Before I start disconnecting sensors, I thought it best to check the codes again.
