vs v6 wont start

[jj81wa]

hi guys and girls sorry first post is trouble shooting and not an intro
anyways

the vs will turn over has fuel and spark tryed different ecu tb tps did the water thing on the cas but wont fire into life all the time
if it does fire (not often) you have to run the starter for ages then it is really rough and struggles to go and sucks heaps of air, then if the accelerater is even slightly touch it wants to stall

any ideas please need it running asap

thaks for your help

ps code says its all good

you may think you have spark but the dfi board might be shot, go check for error codes as well, might give you somewhere to start. Checking error codes VR/VS (Revised)

Sounds like the coil pack,my car did the same thing i checked everything but it still was rough,then finally changed the coil pack now it goes perfect

error codes say its ok my mate that owns the car says he tryed a few different coil packs. is there a way of testing them with a multi meter?
