No pulse on for fuel ingectors, no pusle on for ignition coils

Not if ignition module . Electronic componets when heated up will act just like that . When it dies check spark, fuel pressure right away an find out what quit . Test don't guess . Videos on youtube on testing GM ignition system. Which engine does yours have ? Had option of two different ones . 3.4 an 3.8L . Ignition module or cranhshaft position sensor could be the cause .
Three dual tower ignition coils are mounted to the ICM, and are serviced individually. The ICM performs the following functions:
• The ICM supplies a power and low reference circuit to the CMP and CKP sensors.
• The ICM determines the correct direction of the crankshaft rotation, and cuts spark and fuel delivery to prevent damage from backfiring if reverse rotation is detected.
• The ICM determines the correct coil triggering sequence, based on how many 18 X ON-OFF pulses occur during a sync pulse. This coil sequencing occurs at start-up, and is remembered by the ICM. After the engine is running, the ICM will continue to trigger the coils without the CKP sync pulse.
• The ICM inputs 18 X and 3 X reference signals to the PCM.
• The 3 X reference signal is also known as the low resolution engine speed signal. This signal is generated by the ICM using an internal divide-by-six circuit. This circuit divides the 18 X signal pulses by 6. This divider circuit will not begin operation without a sync pulse present at start-up, and without 18 X and 3 X reference signals no fuel injection will occur.

Pull plug wires off same coil when it dies , crank the engine , is there spark ? Ignition Control Modules ICM by Wells featuring Sgt Tech

If it has an ignition module and fuel injectors than absolutely.

Normally it is either missing spark but has injector pulse, this would typically be a bad ignition module or coil.

If it is missing both spark and injector pulse it is more likely a pickup coil in the distributor.

Could need the injectors cleaned. Call around, not all shops do this.

1987 rangers use a device called a TFI module to control ign. timing , this merely triggers a std. coil to fire the center port of distributor cap , this device only controls the coil to fire but does send a pulse for timing back to ecu this sets the base pulse for fuel injection , but its also affected by manifold Air flow and exhaust O2 amounts (closed loop) , but engine should run in base mode (open loop) fuel timing (but not well) , fuel pump relay is enabled to run via ECU output , Now your year ranger had a tech bulletin out on fuel pumps , seems they had a problem getting them to work after a fuel filter was replaced , something about a false backpressure , no if you have no/low fuel pressure then id look at fuel pump power 1st then fuel pump itself assuming you've already tried a new filter of course

It sounds like a mechanical problem to me , 225 psi compression seams a bit high, normally 150 to 180 . Couldn't be coils , cylinders 1 and 4, and 2 and 3. are companion cylinders share same coil. ! Do you have a fuel pressure gauge ? Do a fuel injector balance test.You don't have plug wires , you have the ignition control module an coils in what GM calls a ignition cassette , sits on top of valve cover ? plugs in center of head ?Check out some of this guys videos . ask him questions , he's a automotive repair tech. plus teacher ! he has a lot of different video on misfire detection .
How to test fuel pressure injector pulse and spark with basic tools

If the injectors show a pusle with the tester you must have no fuel pressure at the injector or it is defective.

check for injector pulse if no pulse cam sensor is bad

The ECM or electronic control module does fire the injectors, however, the injector pulse that the control module uses to fire the injectors is generated from the igniton module inside of the distributor and then the injector pulse is processed through the control module.

Most likely the ignition module that is inside of the distributor is faulty, or there is a damaged or grounded wire between the control module and the control unit. If there is no problem to be found with the ignition module inside of the distributor or with the wiring between the control module and the ignition module inside of the distributor, then the problem will be with the electronic control module itself. Also, check all of the fuses to the ECM.

Let me know if you require any further assistance.

check your coil wire and your module sensor on the distributer make sure its connected also the fuel filter could be clogged and stopping the fuel from getting to the fuel ingectors

Check out your oil sending unit, fuel pump and relay, check for power (might be a fuse), the ignition control module (which if you remove it, can be tested for free at AUTO-ZONE), any related wiring, pick-up coil (inside the distributor), and possibly the ignition switch. If I can be any more help just as away.
