So, I’ve been having this issue where my vehicle shuts off randomly on the road and it’s to the point where I’m having to get pulled home. I’ve replaced the MAF, crank sensor, and cam sensor. I’ve also done a tune up recently as well. It idles rough when stopped. It cranks on every time but dies again idk what to do now. Any answers would be helpful. Appreciate it.

It is common for these cars for the fuel pump to go out, when the engine stops running turn the key off, then back on again without cranking the engine over you should hear the pump running in the tank for about 5 seconds if not, the pump is bad. Here is how you can change it out in the images below. Please let us know what you find. We are interested to see what it is.
