yeah, generally somewhere around the throttle cable... when you pull the cable wide open there will be a part of that linkage that will hit a switch. Check to see if this bad boy is opening (test continuity)

they are low resistance devices you want to have acurate readings check the inductance....
I have 3 diplomas in Electronics and computers I know my stuff. they have an inductance not a resistance.
inductance works by creating a magnetic field around the wires this field then provides the resistance tot he electron flow. trust me it's this you want to measure.

and yes you are the most correct, its an electro magnet which causes the inductance which is the basis of a solenoid

anyways according to the diagram you posted injectors are inductors and should have inductance measured...
anyways,
if you want help trouble shooting the fuel stuff let me know it's not hard for me to measure stuff it's juts hard to say how to measure stuff....

ok first step check continuity from each wire at the injector to clip C173
if those are find then check from Connector C313 (other side of C173) to connector C415 (A connector to the ECU) once you've checked those conntinuity I will go into details later of checking pulse width of the injector pulses and stuff
remember you do this check with the car off...
basically you want to make sure each wire is connected.. so one end of the multimeter on one wire on the injector and the other probe on the other end of that same wire on connector C173 and it shoudl read a very very low resistance

continuity between ecu and injectors just no signal from ecu to injectors

Well you can't see injector signals with a multimeter .... they are on duty cycles (on off over and over again fast) this results in no reading on the multimeter...
to get a reading you have to use an oscilliscope

yes but it goes quick enough that you won't see it ... your multimeter (and the rest of the multimeters around) are 2 slow to measure the change in voltage..... get a fluke meter (retail is like 2000 bucks) or get a used osciliscope (around 900 bucks) and you'll be able to see the pulse train signal to the injectors.
an osciliscope is what you need now.

see if carquest or canadian tire has one, they are inexpensive.
