Hey Guys, been a while since i last posted, (probably a good thing haha).
bit of backstory for those who love reading.
I"ve had my 2005 VZ acclaim wagon LE0 for a few years now, bought it cheap at $600 with a supposed snapped timing chain, well it was just a snapped valve spring so easy fix. all was well for about 12 months then the timing chain started the dreaded rattle, so i replaced them with the old eBay special kit for $180 and that got me out trouble for about 18 months so i cant complain.
now i was on the way home from work one day, traveling uphill, auto downshifted and then clunk and the engine died and wouldnt restart. i assumed the timing chains let go so on the car trailer it goes, took it home and was ready to take it to scrap. my old man wanted it so i gave it to him to do whatever he wanted.
he proceeded to strip the front of the engine and inspect. what he found was the timing chains in tact and tight as they should be. what he also found was the timing gear had actually sheared the dowel pin on the crank and in turn has bent majority of the valves.
purchased a second hand engine, swapped heads over, replaced timing chains and gears again (he anal on changing things while its already stripped) and replaced dowel pin on crank and cleaned everything up in the process.
put it all together finally got it off the hoist started backed it out ready to take it to work the following day, it ran fine, it actually ran better than it did for me. move on to the next day started and moved about 5 meters and it just cut out. i done some digging and found that the fuel pump only primed every now and then (between 10-15 key cycles) and there is no injector pulse. so i assumed the immobiliser has kicked in and cutting fuel. i"ve done a heck of a lot of reading on this issue and cant for the life of me figure this out. what i have added to my collective knowledge is that the ecu dieing is a far more common thing than it should be, and that the whole linking ecu bim and pcm is a hell of process to navigate for the backyard fixerupperer that likes to do things on the cheap.
what i have tried so far.
-Bridge fuel pump relay, fuel pump runs
-removed fuel rail and cranked while fuel pump relay is bridged, no injectors are firing
-got my hands on a complete set of ecu, bim, pim and fob, installed this afternoon but problem still perisists.
-starts on aerostart so it has spark and timing.
I am absolutely stumped at what do next as my original plan on taking it to scrap is looking pretty bloody good right now.
appreciate any input you guys can provide as you are all a very knowlageble bunch.
sorry for the essay but i always see you lot asking for more information so the more i add here the less likely ill p*ss you lot off
2005 VZ Wagon Acclaim LE0 Alloytec auto
TL;DR
alloytec died stopped running, now have no injector pulse or fuel pump.
