Please can I have the power and ground input to the ECU. The ECU fuse keeps blowing each time I cycle the key to ACC position. I need the ECU diagram for power and ground which are responsible for powering the ECU.

I have seen a shorted ignition coil; fuel injector or oxygen sensor cause this problem FYI. Here is a guide to help you check the wiring and I have included the PCM and engine wiring diagrams so you can run the test and see how the system works.

Check out the images (below). Let us know what happens and please upload pictures or videos of the problem so we can see what's going on.

Thank you, my friend. I disconnected all the injectors connectors, ignition coil connectors, airflow etc., and now the short circuit which keeps blowing off the ECU fuse 15amps, has been fixed, but I still notice that my ECU is not powered on, no check engine on dash. After my check comes in, I will then move to identify which part was blowing of the ECU fuse. Please if any help more I will appreciate.

Actually, if I had just directly the ground and power diagram input of the ECU, it’s easy for me to work my way around.

That’s a good question you have asked, I will reply once I begin to plug each part I disconnected. When I get to the part which was shorted, I will expect the fuse to blow up. But I pull out all the connectors of the injectors, ignition coils, 02 sensors. I need just the ground and power input to the ECU.

My friend Ken, please check well and see if it’s diagram for the ecu I am referring to. Let me send you an image of the ECU and its connectors. I have taken a good look and the exam diagram, not very sure it is for my PCM.

Yep, those are the correct wiring diagrams I double checked. I do see a tiny bit of corrosion on a couple of the terminals on the PCM though which can cause the issue. Can you double check the power and grounds? Also, I would check the sensor wires to see if one is melted to ground.
