I changed the battery in my 1998 mustang srs and now I get no fuel to the injecters. Will start if I use staring fluid and then when the vapors run out the car stops runing. I cant'figure it out did I do something wrong when I changed the battery?

Question edited for clarity, spelling and duplication.
Question moved to model category.

Check the fuel pump relay first, and then check fuel pump pressure.

In the drivers side trunk there is a red button it's the fuel pump shut off switch when you changed the battery something mite have triggered the switch to trip if not could be the mass air flow sensor or fuel pump shorted out some how to check that turn the key to on position and see if you hear it come on it will about 3 to 5 seconds you should hear it if not check that switch and fuse what you describe sounds like a fuel issue

The computer controls the injection of the fuel. If you look at the wiring diagram you will note the bottom 4 pins that are the negative and positive to the left and right injection. Atleast on my 1991 it is .Could be the ecm or computer is sending a false signal or not sending one at all. A sign of this is the fuel pump in the gas tank can be heard and will continue to run as if pressure in the fuel system is not building. Tthe truck want crank as if no fuel. When starter fluid is injected into the Throttle body the egine will start and run untill fluid is used up. It will keep running as long as fluid is added.

To promote easy starting, all gasolines contain volatile constituents that under some conditions, such as high ambient temperature, tend to produce more vapor than the fuel-system vents can handle. The action of an engine-mounted fuel pump, in decreasing the pressure at its inlet, tends to vaporize the fuel. If the vapor forms faster than the pump can draw it from the fuel line, the flow of fuel to a carburetor is effectively stopped and the engine stalls. Vapor lock is much less likely on a fuel-injected engine with an electric pump in the fuel tank. However, an engine with port fuel injection may experience vapor lock if the injector or fuel overheats, or if the Reid vapor pressure of the fuel is too high.

Thats usally a bad battery or bad battery cable connections. If the battery is garunteed to be good and charged, then start looking for a loose terminal or heavily corroded terminals.

Running out of gas on a fuel injected vehicle, is very bad. Mostly, due to the fuel lines get pumped up with compressed fuel vapor. The pump can quit from running dry, & need replaced. See if youcan find the shrader valve on the fuel line, easily found on most GM's, usually none on Fords. I sometimes crack the rear fuel line (steel) on end of fuel rail. Crank a few times with the ECM fuse out so it cannot accidentally fire, if fuel comes out. Another alternative, until the fuel pump get fuel to the fuel rail.....is spray a few short shots of "starting fluid" on the air filter. (about a 4 second count). SpraY; 1 ONE THOUSAND, 2 ONE THOUSAND,3 ONE THOUSAND, 4. No more than that, then put the filter back in, close the box quickly,without snapping in & crank. DOes it run then, if it sputters & spurts, proably needs a fuel pump. On fuel injected vehicles, they are usually in the tank.

Try some staring fluid or a few tablespoons of fuel in the intake manifold at the throttle body.
If the car starts and runs for a few seconds, the fuel delivery has a problem ( like a fuel pump or clogged fuel injector).

If it doesn't start up immediately, then it's a possible spark delivery problem.

That should narrow things down a bit.

I suspect the fuel injection is poor. Try to check the fuel pump, there maybe no much pressure from the pump.

have a mechanic scan for computer codes this will put you in a better direction than just changing parts although it wont tell you the exact problem

Actually vapor lock refers to a condition in the intake manifold on a carbureted engine. You don't have vapor lock. What you may have is a filter inside the tank, its nicknamed a sock. Its a fine mesh screen and may be plugging up. When you pull the fuel line the fuel flows back and unblocks a small section , until it starts too **** again and re plugs. You may also have fuel pump that starts to lose power when its gets hot. Lee
