SOURCE: no pulse at injectors
The normal way that injectors are controlled is via the permanent application (ignition on obviously) to one side of the coil that operates the enclosed piston, and the precisely timed application of ground (negative) to the other side of the coil.
The transistors that control this switching under the command of the engine computer are typically contained within the computer itself.
Measuring the voltage at the injectors is not productive since the common multimeter is incapable of detecting the very short pulses that activate the coil. Some kind of visual means would be needed to observe this pulse such as an oscilloscope or an engine analyzer equipped with a 'scope.
It's unlikely that all of the switching transistors (or the injectors) have failed simultaneously so either the computer has a problem or there is no fuel being delivered to the fuel rail that feeds the injectors. You should find a pressure regulator that sits between the fuel line coming from the tank that controls the fuel pressure for the injectors. This device seem to be a sore point in many vehicles and can make it appear that the injectors are not working. Many fuel rails have a fitting similar to a tire valve to allow the testing of the pressure being delivered. I would recommend you check this before assuming that the injectors are at fault.

the injectors are fired thru the engine cotrol module but it gets its signal to fire from the pick-up located inside the distributor if you are loosing injector pulse only the ignition module is bad if you are also loosing spark when you loose injector pulse your pick up is causing the problem if you replace the pick-up i recomend you change the ignition module when doing so because they work together and you have to remove the distributor to change the pick-up

SOURCE: Crank Sensor in 94 Isuzu Rodeo
it's on the bottom of the motor, towards the back on the passenger side. It has a small clip of wires and one screw holding it on. You may want to pull it up on ramps- if it'll run- otherwise, get under the Rodeo, it's up a little higher than the oil pan, and to the passenger side. (it's right on top of the two lines that run to the bottom of the radiator.) You will need a 10mm socket to remove it. I have added a few pics showing the location (i just completed this task myself)

Hi there, Joel here 20 year master mechanic. For the faulting to the injector pulse and power, the control mod in the distributor controls fuel and spark. You're going to have to replace the control mod. I believe AutoZone carries these at 26.99 p/n DR126. Hope this helps.
