My adhd is fighting me on reading those wiring diagrams,?
I would suggest you do this..it will help now and in future

grab a piece of paper and pencil, and DRAW the relevant circuit only. Write down the color of each wire in a table

Yes, it takes a few minutes, but ultimately, it is the only real way around the problem you state

Most people have (a similar) issue to you when it comes to circuit diagrams

If you do what I say, your mind will be clear. It is what I often have to do, working with auto electrics does require some skill, practice and learning

So I did the thing this weekend.

i was preparing to start peeling the harness apart to find the splice between ASD and FPR but figured i would swap the pcm first. To my surprise there was no hesitation after the swap. Immediate fuel prime as it should. I actually swapped the dirty pcm back just to re-confirm the issue. Dirty pcm back in and we are back to delayed prime - i suppose that's enough for me!


I may venture into splitting the now old pcm to look for visible damage? Otherwise I'm putting this one behind me
