"revised" read at bottim

Hello jeepers...
I've owned jeeps now for 33 yrs from old Willie's to brand new.

My now 01 jeep grand cherokee 4.7 is experiencing some coughing. Had my other one not been run over by a semi, my wife's jeep stolen now down to this and disabled for 3 weeks and running out of time.

I've replaced all sensors (all of them twice). It fires then runs friggen new for 1 min after each replacement. Then back to coughing. If I drive it it will die in motion I was just rear-ended last week from this so I'm not about to try. I can hear it's running about half normal, yet if you Rev it up it stays rough but throaty and Dosnt limit out or hesitate while doing so. Exhaust is clear smells fine. All connectors to sensors r stable. I have noticed 3amos to all connectors instead of 5 and the 4 pin connector on throttle body has 0zero. The holes r so. Small not sure my reader probes r reaching metal.

In my wrecked scooped up 400hp 99 I have alot of new parts like fuel pump but what a headache like the crank sensor is when it's 25 degrees outside. So when it dies it will fie back up after a few hrs and sometime when it won't start I listen for fuel pump and I off and on it 3 or 4 times and fires. My common sense says it's that. My common sense also says that this has been happening for months it's bits tiny bit until suddenly the stalling....
I though fuel pumps either work or don't work? I've never really had a pump problem in the past, what a huge job only to find like everything else it's not that. I'm about to dynamite it I'm so frustrated and now Beyond​​ my ability to trouble shoot.

I have an expensive 1and 2 reader and throwing no codes. Says nothing. Present in computer. It used to say heater and transmission (fixed)... Then and since zero codes..

I just need this to run long enough so we can buy a more reliable vehicle since we're down to one and we're all about to get hungry not being able to shop. Lmao true story...


Well that's all I can think of presently.
Thank u very much I appreciate the threads here as Uve read them. All.. Long b4 posting and waisting anymore of all you nice folks. I'm stumped
Any thoughts.

(new thought after above post)
Until now I was able to erase codes and would run fine until I shut it off then wouldn't restart. Now since no codes it running rough and stall instead kinda of a switch.. Confusing as hell


Revised:

Tps has 12v with key on and zero with key off
