Default P0191 , car dies shortly afterwards

Hello Gents;

Havenít had issues with my car in a while. Today in short sequence:

-1-Car started stuttering at low speed
-2-light came on code P0191. No other codes
-3-turned car of, went into target, car came on again
-4-on way out of target car lost almost all power and eventually dies at light
-5-Able to restart giving gas after a few tries and car resumed driving normally all the way home. 2 miles

what does this sound like? I did have to replace the fuel rail pressure module in my old X type, very easy, but I am worried this may be a fuel pump.

The car has 66k miles

Any input welcome. Thanks

First thing I would check/change because it's cheap is the fuel filter.

Thanks, I just changed it this morning....Car ran well for a while, but eventually stuttered, but no codes today. Stuttered into the gas station and put some gas (it had 1/4 tank, filled it to 3/4) and car performed well after that.

In my original post, I forgot to mention that yesterday the temperature reached 92. It was hot . First hot day of the year here. Failing pumps do not like heat.

Based on my past experience this has to be the fuel pump. This is my daily driver and I occasionally have my grandmother riding in this car. I can not have it break down randomly.

Is replacing the pump a job any mechanic can do, or are there any X type eccentricities that would warrant me paying more for a ďspecialistĒ? I will not be cutting holes under the seat unless the labor is 10 hours. But if itís a matter of a mechanic lowering the gas tank like in any other car, then I will go that route.

Kindly let let me know what to watch out for when having the tank lowered and pump replaced...

Thanks for the videos.

I see that that it is in fact a 10 hour job to drop the tank. I was prepared to pay, but not that much. Also, I hate the fact that rear suspension and exhaust parts have to be removed.

If the car is still running tomorrow, I will go to a body shop and ask if they can cut the hole according to the specifications on the video. I donít want to get in and make a mess, I would like a clean cut, plus I donít have the tools necessary nor the patience to make perfect cuts.

Spike, I have a very comprehensive thread on replacing my fuel pump by cutting an access hole with really good contributions by other members. It has instructions, pictures, tool used, measurements. Doing it yourself is really not too hard. I went this route because dropping the tank is so expensive. The LOL, is I just had to pay to do just that to replace the rubber hose on the gas tank to fix an Evap Leak, smfh! The snag originally was taking off the fuel pump ring. You really do need to have the removal tool that makes it slick. And the first lose of my ordering the gasket was a hiccup. If I had all that in place before starting the project, Iīd say it's a 3 hour job.

In my thread there is also member's post to buy just the actual cylinder pump and be able to replace it in the existing assembly. If mine goes again, I'll go that route, but mine had more wrong with it than just the pump (sensor, float).
