If all injectors are failing did you check for a blown fuse?

yes all fuses are good and relays also.

I just had this issue. I thought it was the fuel pump at first. Come to find out my gas gauge wasn't working properly and I didn't have enough gas.

I wish the gas gauge issue would be figured out already. Not even the Infiniti in my area knows what to do except to replace my entire cluster. Eff that.

I wish it would be just that but that thing is filled up to the top

I'd take off the lower back seat and see if the fuel pump is even engaging. The fuel pump is pretty cheap to replace and shouldn't take you more than 2 hours to replace...

yea its kicking on

I would recheck how the hoses and vacuum lines are put back to make sure they go in the right place/order. Good luck!

Did you check the fuel pump pressure with a pressure gauge?
