test your coils, If OK, then the DFI unit underneath the coils may be gone......

thanks for reply here

what resistance should be on coils and if its dfi how much are they ?

 

[futronix]

to test the coil block (V6) :

1) remove each coil one at a time....
2) turn upside down and check resistance between (primary) two terminals
3) should read between 0.3 - 1.5ohms (When Coil is cold!!)
4) measure the resistance between the two terminals on top of the coil (secondary)
5) should read betwwen 5000-10000ohms (when coil is cold!!)

not exactly sure on prices for a new DFI I thought it was around $200.00 from Holden and if im right comes with new coil packs...

or if u want to make sure it is the DFI... do what i did and swap one around from another VS to test..... you could even swap the whole DFI and coil pack still attached to make it easier.
