Alright, swapped rebuilt ALH from 99.5 mk4 into a rabbit
fresh motor after rebuild
checked timing a number of times
fuel is at the injectors
motor is cranking but will not catch
running no intake boot (straight to manifold) obvious cranking wooshing can be heard
injection pump has been adjusted all the way advanced and retarded.
tried with and without preheating the glow plugs (it's ~75 at night here)
only error code i've got is 17970 - Quantity Adjuster Upper Limit Attained - this number is reading 0 no matter what I do in vag-com, i'm unsure if this is because the motor is not running or because it has an issue. I'm going to check the wiring between the ECM & the injector pump but beyond that I can't find much on the quantity adjuster stopping cars from running but my VW tech friend's say it will.
Can I clean it? can I order a new one? is this really my problem? what else am I missing/need to check? is my pump dead? is my ecm dead? any code blocks I should be reading to diagnose this and what should I be seeing in them? i'm open to any and all suggestions!
