Code P0113

So, I replaced a list of things in this SUV, and I finally got rid of all the codes except I'm down to p0113. Replaced the mass air flow sensor which also contains the IAT. the air filter is brand new. I also replace the wiring harness connector that goes to the MAF. And I still can't leave my parking lot without the wrench light coming on and then maybe I have a minute after that before it does, and I don't know what else to do. Because of this I haven't been able to work for 3 months. The person who had it before me said he took care of it and to him that was parking it in a garage for 5 years with the emissions light on. So needless to say, I've pretty much replaced about thirteen different things in this vehicle I don't know what to do now and I'm exhausted from this and because of it I've about to lose everything it's destroyed me financially. It's gone to a repair shop I paid $700.00 for a massive gas leak and not even 24 hours later it shut off on me twice but everything else has been fixed. I just don't know how to fix this or even where to start to try to fix it. And what do I do about an ABS code c1991? Can't find any information anywhere. Its module calibration failure does that mean I need a new module or I'm going to have to take it in for somebody just to calibrate it?
Oh, and I did a PCM clear by hooking a jumper wire to the battery connectors and I let it set for quite a while and turned it back on. Before that, the fuse kept blowing but after I did the clear the fuse didn't blow anymore but that code still comes up. Oh yeah, and one more thing after replacing everything with the engine on and running my scanner isn't even able to recognize that I have a MAF. For MAF it says zero and for IAT it says -40. Doesn't change no matter what I do and that's with everything new and replaced it still reads as nothing
