99 Suzuki Esteem DTC reading

Hello two car pros. I have recently purchased an 1999 Suzuki Esteem 1.6L. When I first drove the vehicle I had to hold my foot on the gas pedal all the way down before accerleration. Then the vehicle would start/crank over with a low idle and NOT accelerate nor give out any RPM. And now the vehicle just doesn't start whatsoever, although it cranks but doesn't start.

I have replaced the plugs and one coil pack, and an MAF, before the car stopped starting. However I have a DTC Scan but it says that no codes are stored on the computer? But my Live Date gives me:
Fuel Sys: OL
ECT (F): 62
MAP (inHg): 29.2
Eng RPM: 0
IAT(F): 64
TPS (%): 9.0
O2S B1 Si (v): 0
O2S B1 S2: 1.275
STFT: 0

Yet. How can I figure out what these codes are telling me? It has been exremely difficult to locate any manual on this vehicle!

BTW: I did use another scan that gave me the code of P0301: Cylinder #1 misfire as well as this starting point.
