Checked relays. And fuses, replaced fuel pump and filter, new coil pack, new crank sensor. Plugs and wires ak. Cylinder 3&4 is grounded before the key is turned on, something grounding out inside the pcm before the key is turned on(pcm is hot even when not on) engine won't start lup, how do you get code readings, did try removing sensors and replacing one at a time(only time we got a code reading)

Hi there,

Thank you for the donation,

When you say the ECU (PCM) is hot, do you mean hot to touch? If so you will have a short and this will have to be looked into, you can get the ECU bench tested my a specialist workshop, I would start with checking earths for back voltage and getting the ECU tested.
