weird MAF problem

Recently my car has developed a stalling issue. So in an attempt to narrow down the causes I dumped the computer codes. One of the codes I recieved was code 66 MAF below minimum test voltage.

I did a quick test and disconnected the MAF harness. Nothing happened. I took this to mean the MAF was in fact dead. I went on to other chores (cleaning the IAC and resetting the idle and TPS). Later I came back to test the MAF with a voltmeter. To my suprise I got a reading of about 12-13 volts on pins A and B and a reading of about 1 volt on C and D at idle. So I decided to disconnect the MAF again to see what happened. The engine stumbled and started to run like crap.

Could this on and off again failure of the MAF be a sign that it is getting ready to die? Should I go about replacing it anyway? Also could this be the cause of my stalling issue? Also the car seemed to run fine when I took her on a test run. She usually stalled atleast once if left to idle for to long or taken on long trips. Don't know if this is an indication that the problem is solved however. I am afraid to go on long test drives.

I'm clearing the codes and I will see what comes up again if the problem resurfaces.

yeah I just need to get some tamper proof torx bits. PITA lol.

Well I figured out that its not the MAF at least. The car is refusing to start again. Checked the codes and I got a 63, 87 and a 96. The fuel pump codes are what are bothering me. Seems I have found the problem. Any ideas on where to start looking. Could this be a pump failure (I can hear the pump prime) or is this more likely to be a failure in the wiring?

The TPS code is odd since I have reset it three times and I keep getting that code. I checked it again and I had .98 volts.
