Help ranger wont start

The other day truck was running fine made one stop, started up drove about 30 yards it dies. I have spark, fuel, fuel pump works, pressure up to the injectors. Don't know what to do now. Some say its the injectors but how can I test them if I can't even start the truck. Just at a stand still any suggestions would be helpful thank you

Crank engine then pull out a spark plug, if it is wet with fuel then injectors are working, if it is dry then they are not working.

Put some gas into the intake, or get a spray can of starting fluid(ether) and spray some into the intake.
Try to start, if it starts then dies, fuel is the issue
If it doesn't start then spark is the issue

On 2.3l engines only the exhaust side spark plugs work when cranking engine, both sides fire above 500RPMs(so after start up), just FYI.

The CKP(crank position) sensor behind the main pulley is the only "sensor" that can cause a no start, when you crank the engine the CKP sensor sends a Pulse to the ICM(ignition control module, located IN the Computer on a '97), this pulse tells computer to start spark and fuel injectors, so if CKP sensor fails(or wires to it do) then computer doesn't know you are trying to start engine, so no spark and no fuel.

If you have spark(or fuel) then CKP sensor is working.
