When is the fuel pump relay turned on?
The fuel pump relay is activated whenever the ignition is turned on. A fuel pump relay functions primarily to maintain a consistent voltage supply to the fuel pump. The ignition or powertrain control module (PCM) usually controls the fuel pump relay.
Is the fuel pump relay controlled by the PCM?
Consequently, the fuel pump relay is usually controlled by, the ignition or powertrain control module (PCM). As a result, when switched on, the fuel pump relay; will provide current to the fuel pump, so that it may function. Therefore, any faults with it, can cause fuel pump issues.
Pins 21 & 22 at the PCM connector go to the crank sensor. With the multimeter set to AC voltage I verified that the crank sensor produced an ac voltage signal between .4 and 2.0 volts when the engine was being cranked (per other threads).
How to test a fuel pump relay on a 94 Ford Ranger?

Can a manual PCM work in a manual truck?
If you put the auto PCM in a manual truck, the computer still sends the signals but there are no wires in the connector running to an auto trans to receive them so the signals are ignored. An automatic truck with a manual pcm will be looking for signals from the pcm that it never gets, so it will not do well.
Fuel pump turns on at KOEO but does not turn off after 1-2 seconds like normal. Appears to have no spark or injector pulse. The Check Engine light does NOT come on at any point when trying to start. SPARK: Looked for spark with inline spark test light and also old fashioned method – plug in wire held against good ground.
Can a faulty PCM cause low fuel mileage?
Since the fuel pressure regulator is given specific air/fuel mixture directions from the PCM, it should always maintain the proper mixture. A faulty fuel pressure regulator can also be to blame for a sudden decrease in fuel mileage. These symptoms can also occur with a plugged fuel filter, failing fuel pump, or faulty PCM.
