Will it run with the MAF disconnected? Does the MAF sensor have +5v reference at the connector?

Yes I tested the Maf sensor good voltage and also tried to disconnect but same issue, I also changed the plugs and fuel filter i think its better to do the fuel pump as well as its been standing for about 5 mhonts... but not sure about the results
