Does it try to start if you spray starting fluid into the throttle body ?
Are you getting power and ground pulse to the injectors ?

year/make/model/engine size??? Do a fuel pressure test to see what the pressure is. Low/no pressure= poor spray

You would put on a new crank sensor because the ignition system won't work, it gives no spark. So now do you have spark at a spark plug wire end? A blue consistent spark? Probably good ignition system, as long as all spark plugs get a spark.

One thing you always want to check with no start is the fuel pressure. Turning the key to on should turn the fuel pump on and put pressure in the fuel rail at the engine. Autozone and maybe others rent or loan fuel pressure gauges. Multi-port injection systems have high pressure specifications, around 40 psi normally. That is what the injectors require to spray out fuel when they pulse and open the nozzles.

With the injector circuit, the first thing to check is if each injector has power to it with the key in ON. One power wire and one ground wire goes to each injector. The power wire is from a fuse that is powered with key on or key in start, and then it is spliced to all of the injectors. The injector grounds all run into the engine computer, where the circuit can be internally grounded for a split second and cause the injector to pulse. But anytime the key is on, the injectors have steady voltage available to them.

Spark at plugs? Fuel filter? Pressure on injector delivery line? Pressure relief valve? You may be able to measure fuel pressure at the pressure relief valve location. and return line. If you have spark, I'd say it's a fuel supply problem

Are you not getting fuel to the throttle body? Or are you not getting any injector pulse? BIG DIFFERENCE!

If you have lost injector pulse and spark at the same time, the most likely cause would be a failed distributor module.

Pull off one injector connector and use a test light or voltmeter to see if one wire has power with key on.
Power to the injectors is fed through the ignition switch, so with key on, you should have power there. The injector ground is inside the ECM. If you have power, you'll have to diagnose the circuit for why computer doesn't ground the circuit when it should.

You should replace the fuel filter and check for vaccum leaks. Also you should check the compression of your vehicle this might solve your problem.

Check the fuel injector ground circuit from the ECM
