Vl kicks but wont start and if it does its missing

[DAVO84]

I JUST BOUGHT A VL COMMODORE AND IT WONT START

I HAVE TRIED

WATER IN THE DIZZY NOTHING THERE
AIR FLOW NOTHING THERE
O2 CENSER NOTHING THERE
SPARK PLUG LEADS ARE FINE

i cleaned the spark plugs with sand paper and it started first go but then started missing and stopped i pulled them out and i think there were 2 that were black not from oil i think its from fuel it wasn't wet

i cant see changing the spark plugs would make a difference

would it be a fuel problem injectors maybe

its also not the fuel pump thats working fine

im racking my brains trying to figure it out any ideas???

Air flow meter or crank angle sensor. Do a search there is so much info on here regarding vls not starting.
Try this unplug the air flow meter and try start your car. If it starts and idles fine your afm is failing. If your not getting spark it's most likely the cas or coil

haha yeh man i used to scream at all my VL's n VLTs no starting ..
Basically all i done for "mine" no sayin everyone elses but the arc points inside the dizzy cap
i just sandpapered the corosion on them and started for me ..

like said check the site for every possibility .. there a pretty easy motor to diagnose and work on

ok i have read through the forum and there is quite alot of threads i didn't know about

i replaced the in tank fuel pump
spark plugs and leads
CAS
ignition coil
coolant temp sensor
unplugged the air flow meter still wont start
i cleaned all the contacts with contact cleaner
i cleaned out the throttle body

its also back firing out the exhaust and airbox

anyone got any ideas of what i could do im out of ideas??

if its backfired like u have said. it would have popped your airflow meter hot wire... as its thinner than hair.

pull back the rubber boot on the CAS plug and check the wires are all still connected and not corroded off. this is common.

when u did the CAS did u remove the dizzy?

try another afm from a mate or wrecker.. just test it before u buy one from a wrecker.
inspect the thin wire in the afm... but im gonna roll with the AFM.

and u trying to start it with your foot pumping throttle is not going to do anything as its an injected engine not carby..
this is how u backfire it and damage afm's

checked the codes ? pretty easy to do.. Ive had them when the TPS isnt reading they get dicky after they been sitting a while

i had another play around with it yesterday and got it going turned the dizzy around 180 degrees it was firing on the exhaust stroke thats why it was backfiring out the exhaust the airflow metre is fine only problem now is its missing but that shouldnt be too bad to figure out thanks

 

[detox_nath83]

Very good. Hehe the next thing I would have said if u took the dizzy
Out was gonna be didn't put it 180 out.

ok i have it started it will idle fine but it dies when you accelerate though. i unplugged the airflow censer and it died just cut out shouldn't it still run with it out?
