Fuel pumps are not working fires up if u spray start fluid in carb

Are the injectors firing ? Do you have a security light lit on the instrument cluster ?

NO if it was timing belt it would not start on carb cleaner
check all you fuel connections lines and electrical, its not turning the fuel on

if it was the fuel pump engine should start with starter spray at least for a second or two, so, it sounds like your fuel pump is bad.
turn ignition to run and try hearing the pump run.

Have you checked base fuel pressure with a gauge, and do you have power and a ground signal to the injectors ?

Most likely fuel pump but could be other things try starter fluid if it fires its possible pump problem

could be alot of different things. try disconnecting the fuel line at the motor to see if you have fuel when the key is turned on. (put open end of line in a bottle preferrably clear to inspect for debris or water) If not replace fuel filter. could be a clogged catalytic converter, could be clogged injectors (if when you remove the fuel line at the motor there is fuel coming out when ignition is turned on) could be air filter is clogged. You can get rid of most of these without disconnecting anything by getting a can of choke and carb cleaner. Use it like you would starter fluid. (dont use starter fluid as it may lock up your motor) disconnect air filter and spray about a 2 second full spray into the air filter hose. have someone try to start the car. If it starts then you know its a fuel delivery problem and narrows it down for you.

If you think its fuel, spray some starter fluid inthe throttle body. If it fires up, you have a fuel problem, otherwise, check your spark plug wires, distributor cap and rotor. Also, check your fuses.

If the motor doesn't turn over at all then it's probably a starter/solenoid problem. If it turns over but won't fire up, get some starting fluid from auto parts store and spray some into intake. If it fires there's a fuel delivery problem. So change fuel filter and try again. If that doesn't work, then change fuel pump.

Turn key forward listen for the fuel pump to pressurize if you don't here anything then your fuel pump needs replaced and it's in the tank.

if starter fluid made it chug, I would suspect fuel pump fuse, relay or pump, also fuel filter.
