My 97 S10 want start, but if you spray starter fluid in the intake it will for a few seconds

Spray some starter fluid in the intake. If it runs for a few seconds, the problem is probably the fuel pump.

no
you fix the reason why the injectors are not working
could be fuel pump , pressure regulator , injectors , wiring or ECM
have the fault codes read

Kelly, could be a few issues, security lock out, crank sensor, fuel pump fuse/relay, faulty new pump,faulty ignition switch, etc. Attached links may help you diagnose the crank no start issue you are having.
Check the attached links,video,instruction and guides, Good luck

if it starts with starter fluid then its a fuel problem. check the fuel pressure and volume with a gage. these require at least 56lbs pressure to open the injectors and if the pressure is at 52lbs the they will not open. these use the pressure to open the poppet injectors and have a problem with the spider lines cracking and leaking fuel inside the intake. this is probably why it won`t start on its own.

Not a great idea if you haven't done this before. You can start a fire, or even ruin your engine. However, in general, remove the air cleaner and spray starter fluid into carb (or throttle body) about one second (one Mississippi) and try to start. If it starts and continues to run, rock on. If it runs a few seconds and dies, you have ither issue and are not getting fuel delivery. Seek help!

Do you have normal fuel pressure when you first crank it ?

there is a large tube that goes to your throttle body (you do not have a carb), remove it and spray there-be careful, starter fluid is highly explosive, spray 2 or 3 short bursts into the top of the throttle body opening, and install the tube (you don't have to tighten the clamp). You may have to repeat this a few times, if you can only get the car to run for a few seconds 3 or 4 times, and it will not run on it's own, you have a fuel delivery problem, and no amount of starter fluid is going to fix it.

Check for gas or spark problem on the engine. Check that starting fluid does start the car for a few seconds before dying, indicating a fuel delivery problem, like a fuel pump or circuit to it.

If the car won't start with starting fluid sprayed into the intake, then the ignition system may be at fault, or engine timing.

Well, obviously someone didn't tell you the truth because spraying into intake doesn't make the vehicle turn over any better. You have ignition or fuel delivery problem. Start by taking fuel line off at intake and crank engine a couple times catching any gas in a cup or something. If none, then trace fuel line back and under vehicle til you find filter. Should be under driverside midway back on inside of frame. Change this and try test again. If no gas, see if fuel pump is on motor(mechanical pump). Change this and test again. If not on motor then it's in gas tank(electric pump). Most cases the tank has to be lowered to take out pump, careful not to drop, dent or make sparks. Some came with access through the floor so check that first. Normally you can hear an electric pump come on when you turn the key. Good Luck

possibly the fuel pump, just turn the key on and listen for the fuel pump,will hear it forjust a few sec's
