The motor start only with carb cleaner shot in air

Disconnect the fuel line from the intake and place it into a bucket or some sort of container and then switch on the ignition and see if fuel is being pumped into the container. If no fuel is being pumped find and check the fuel pump fuse. If fuel is being pumped into the container check the line going into the intake manifold for any blockage. You should be able to narrow down where the problem is, be very careful when performing these checks.

What year is it?
4 cyc or V6?

I will assume you has a fresh tank of gas.
Here's a lot of to do / to check list.

clean air filter
clear air passage intake tube
clean mass air sensor MAS with electronic part cleaner
clean carb. or throttle body with carb. cleaner.
check or replace spark plug/wires/cap/rotor
check timing
change coolant (it's over due)
oil change (it's over due)
fuel filter (it's over due)

Give it a little TLC and it me know
