Icon5 02 edge p0113 code

I have an 02 4.0 edge.It is acting up,I recently changed the fuel pump and it worked fine for weeks,now it barely runs throwing code p0113.I changed the maf sensor,I checked the voltage today at 40 degrees or so it is at 3.5 volts.Can anyone tell me what else to check?Thanks for your help.

Unplug the MAF to put it into open loop mode and see if it clears up (the running not the code)

Verify that you have 5 volts into the IAT and that your signal return wire has low resistance by checking it from the IAT to the PCM. not sure if that truck uses the MAF or if it has a seperate IAT sensor. I think it has a seperate sensor in the intake tube. Not sure
