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.

Do you
have the same problem?

There is a link on our home page for reading the counts to figure out the codes from the flasbing check engine light.
