Does the blue-driver have a live data setting? If it does, check to see if there is an RPM signal being generated by the crankshaft position sensor. The PCM uses crankshaft position reference to determine injector sequence, ignition timing, and the presence of misfire. Once the PCM determines the crankshaft position, it begins energizing the injectors in sequence. Something could be failing there. The only thing that confuses me is the idea that it has spark.
When the key is in the ON position and the engine is not running (zero rpm), the Auto Shutdown (ASD) and fuel pump relays de-energize after approximately 1 second. Therefore, battery voltage is not supplied to the fuel pump, ignition coil, fuel injectors, and heated oxygen sensors. So, if you have spark, the sensors should be working. That leaves a wiring problem or a PCM problem.
If you can check for an RPM signal, let me know. If not, we need to start at the injectors and work backward. I would really like to know if all the injectors are doing the same thing. That could help eliminate possibilities.
I attached the wiring schematic below for the entire powertrain management system. I need you to locate the brown wire with a white tracer at each injector. There is a wire splice near the breakout for injectors 5 and 6. Inspect that splice for corrosion or damage.
If it is good, we need to work back to another wire splice which is large. See the schematic. I circled both splices to check. Make sure the same thing is there, no corrosion, and in good condition.
Let me know what you find.
Let me know.
See pics below. Note: I had to cut each page of the schematic in half to make them readable for you. I did overlap them so you can follow from one to the next. I highlighted and wiring involved. Note that the splice sends power to several different components (S112) which is near the IPD module under the hood.
