How do you check Injectors?

[S13Sil40]

So, i understand that with these cars the injectors are in series meaning if one goes out they all do...er, thats what i was told.

How do you individually check fuel injectors being that theyre over a hundred a piece, and changing them all isnt an option for me.

It cranks and cranks and cranks but will not start. New plugs, wire, fuel filter. Pump works (had to deal with a leak when changing fuel filter). Spark plugs are wet after cranking. Battery is charged.
weird thing is...before i changed the fuel filter, it would start but die in 5 seconds. Now it wont even start. coincidence? prob.

could it be anything:
fuel injectors?
crank position sensor?
cam position sensor?
ICM?
fuel pressure regulator?

i think that i remember seeing the SES light come on when the car still ran (a while ago), but i never got around to scanning it. Now that it doesnt drive i cannot get it to autozone to check.
Is there a way to check codes without that computer thingy? Is it possible to rent one?
Is there any place that might rent out a fuel pressure gauge? Autozone doesnt.

thanks

The best test device to check your fuel injectors for the 12v pulse is a NOID light. The other thing you could do is check the fuel injector coil resistance with an ohmmeter. I don't have the values for your GP model but you can check the resistance of each and compare all 6 of them.

If your plugs are wet I doubt you have a problem with the fuel injectors. This seems like a problem with the Crank position sensor or the security system. I would check to see if you are actually getting spark because this sounds more like an ignition problem than a fuel system problem to me.
