So i was on a long drive back from up north.. when i hit traffic right before my exit... of course the car stalls, i noticed it wasnt running right when the rpms suddenly dropped and would rise back up again.. so i got to the shoulder waited 15 minutes and it eventually started... ALthough i did try many times to start it it would turn but no gas getting through.. since then the car has been doin it consistantly im pretty sure it has something to do with the fuel pump but man is it annoying anyone have any issues like this? thanks for any help

I would go with the fuel filter before I would waste time and money on the pump.
Not putting out any codes are you.

First thing before deep diving into the diagnostic,check for a possible loose terminal at the Underhood Bussed Electrical Center (Fuse box) for the fuel pump power supply. There have been reports that this terminal for circuit 120 (Gry) has been loose at the UBEC.

Yeah you can check the fuel filter. You may also want to clean the TB as alot of people have had this same problem and after cleaning the TB it goes away. There is a thread here about it https://www.cobaltss.net/forums/2-0l-lsj-performance-tech-47/idle-problem-cure-finally-116051/ you can check out.

alright so ive cleaned the tb ive checked the fuel filter i had an entire new fuel pump system installed and still the rpms drop and the car stalls anyone have any other ideas.. the cars been in the shop for a good 2 weeks im so rattled

Plugs? Otherwise I'd guess it's solely an electrical problem...check the engine fuse box.

Are you getting any cels if so which ones.

you're positive there's no gas getting to the motor?

I am pretty sure the car runs, it just stalls when he comes to stops.

Is there any way you can get the car logged? That may help to find the problem.

grigs

no it stalls when im moving at any speed in gear.. and power steering and breaks still remain

rnjmur

Yeah, I would see about trying ot get it logged. The should hopefully tell you something about what is going on, whether it is leaning out or what is happening.

could be a loose battery terminal as well.
