Do you need the low pressure or high pressure pump replaced? You get 2 on these

Like @luigisho said, we need to first know which pump you are referring to, and then we need to understand WHY you are looking to replace it. If you are having problems with the stock one, 9/10 times a stock replacement will be fine unless you are wanting to output more power.
typically the stock LPFP (in-tank) can outflow the stock HPFP, but the upgraded HPFP options outflow the LPFP, but you don't NEED to upgrade the LPFP until you are pushing E50 fueling.

Reason being that the Sho with no prior symptoms coming home after filling the tank , sputtered twice n just died on me , tried to restart several times but it would just turn over with no start . While waiting for an hour for transport I tried to restart and it did, drove off ran fine for about ten seconds and it died again . Mechanic stated it sounds like fuel pump, pulled the codes for mass/map sensor fault.

While I'm here what is the widest tire size u can install on stock rim,
That sounds like the module in the trunk going bad.

Name and location of module just for future reference,
So my fuel pump module died
Woke up this AM, remote started the car as usual and let it warm up. Heard it start and idle. 5 mins later I check and car is off. I hit the remote start again and it just cranks. Great. I had a feeling on what it was, and not hearing any fuel pump prime was a big clue. So, I drive to...

Hey guys contacted my local mechanic on Sho repairs and minor progress, he pulled codes P0106,P0234,P0642, replaced both MAP sensors, before I take it to the dreaded dealership what are you guys thoughts . Thanks

Are you running a tune? was the MAP replaced with an incorrect sensor (like 3bar vs 2bar)?
Is there 5v to all the circuit connections? THere are only a few spots in circuit below.
Were the old codes erased after the new stuff was put in? You don't want to chase old codes that may have been resolved.
Use the decision tree in 1st code to determine the next place to check/action to take.
If there are no correlating codes then go to next code.

P0106 MAP SENSOR
Let me backtrack a couple of days. Went in for state safety inspection and failed emissions...................."System not ready for testing" I figures like last year it was related to the LMS tune. Here is what I have done so far...... 1. Removed 4 bar MAP sensor and R/R with OEM sensor 2...

Turbo Over boost Condition
I was driving my car ('13 sho pp, k&n intake, livernois 93 octane tune, and corsa catback) and I floored it at 70mph, rpms stayed at around 5k and barely accelerated. Tune showed code p0234 (turbo overboost condition). Took the tune out and same thing. Intake is tight and I even took it to the...

The Fuel Pump Drive Module is a common failure point as said above. It is easily found for ~$40 online or at local auto parts stores. Dorman makes a "heavy duty" version. Being a 12-13 year old part that has had a recall on some models, replacing this is a good shot. At $40 it is less than the labor charge to get your car in the bay or a stealership. It often fails when hot (after running for a little while). Next thing I would look at (and your mechanic should have) is the fuel pressure from the LPFP and the HPFP. There are 2 very different pumps with very different costs. One is in the tank and one is on the motor..

Replaced pump module, car starts and runs fine at idle, rev the engine a few times and it falls dead,

Use a scan tool to look at your fuel pressures at idle and off idle. When my LPFP went bad, it would lose pressure off idle.

When should u hear the fuel pump priming, I hear no sound coming from it.

For just info is there any recommendations besides the dealership for A PCM replacement .
When you open the door. After the car has been sitting for ~10 min or more.
What does it take for it to restart?

Have you looked at the fuel pressures on a scan tool? It will help you figure out which one is losing pressure and allow you to go from there.
