Ok so im driving, my gas gauge was almost to E, and my car almost shuts off on me meaning my rpm drops to like 100 then bumps back up to regular idle(1000), my Hvac(Ac button, Defrost button, etc.) the lights turns really dim for a brief second then comes back bright again. I fill 8 bucks into my tank and drive home without any that stuff happening... Now also sometimes when i start my car it would go up to reg idle at 1000 then drop to like 100 or even turns off and all that happens when i start it in like a second. I think it may be the fuel pump or injectors but idk, what do you guys think?

Hmmm, so you are able to drive it yea? Well. I would go cheap if I were you. Go with fuel filter first. If that doesn't work, you might want to try the fuel pump. That would be guess also. But all these problems are only upon startup?

When i start it up sometimes the rpm drops really low or turns off, when im driving near to E mark on the gas gauge it would almost die on me with the lights dimming and rpm dropping and then in a brief second it would go back to normal and does it again several times till i fill it with some gas then nothing happens. Oh and i forgot to say that yes i also changed the filter but really didnt solve my problem. It may be the fuel pump i believe but i want to consider all things it can possibly be, ya its drivable as long its not near the E mark lol

Hmmm, Well I'm stumped, lol. I'd jsut keep it away from E aha. I'd replace the fuel pump to make sure, its something that will have to be done sooner or later lol.

have you looked at the wire connections to the coil or to the MAF sensor..if the maf plug wiggles from road bumps..it can sometimes cut in and out like that..same with the coil wire connections..just sumpin else to look at if you dont solve this issue with the fuel pump.
