My fuel gage went out last week now my car sometimes starts sometimes doesn't and turns off when i turn my ac on has anyone had this problem i need help Mechanics are expensive ....i have a feeling its my fuel pump

have you tried your fuel sending unit

Turn your key over to ACC and see if u hear your fuel pump kicks on easiest way to check/eliminate that one and then go from there. Do you have anymore information? When you get it to start does it stay running if you don't try and turn your ac on?

How sure are you that the fuel pump is powered when the key is only set to ACC?

Your correct the key needs to be in the "ON" position for the pump to prime my mistake

Ok checked fuel pump and i hear it so thats fine and tacked it down to my battery replacing it this week hopefully is that thx guys

Is a t25 turbo the stock turbo a gst come with.....?? Again i have never had turbo cars i used to be a muscle car guy

your fuel pump wont come on full blast till you crank the car do to a fuel pump relay but it will prime in the on position. if your car is running and quitting check the crank shaft position sensor i had a 2g talon that would do the same thing i replaced that sensor and everything was fine after that..

Interesting. Are you saying that 2G DSMs have something like the two-step fuel-pump voltage set-up of an Evo?

thats pretty much exactly right. i had to by pass my fuel pump relay to get it to kick on when i was draining the tank in my 2g it only primes when the key is in the on position and then kicks on full blast when you crank the car.

After both checking around and asking around, I find no evidence at all that any DSM ever came with anything like the load-dependent fuel-pump voltage of an Evo X. This is probably a good thing, too. The OE relay that controls the higher voltage on early Evo Xs was a piece of junk and cost several people their engine.
