I have a 97 VS Commodore ute, its a 6.
I have had issues with it not starting - sometimes it will, sometimes it won't.
Did the testing on the Coil pack by removing it and testing primary circuit - all 3 were fine and about the same.
Then tested secondary circuits (where spark plug leads plug on).
The LH coil out of the 3 was not getting a spark, so I replaced it and it seemed ok - did the replacement at auto parts joint so if there was a problem I was already there, Started fine. Drove to a petrol station. Fuelled up, then went to their air pump place and checked tyre pressures.Then to supermarket and bought some filet steak and a coopers green long neck for dinner to celebrate.
Hooked up the trailer and went and picked up some stuff - no problems to get home.
So thats more than 6 times in a row it started like a dream.
Then I went to move car and trailer - wouldn't start.
Checked the leads onto the coil - once was not pushed down properly, pushed the bugger down.
It started so I went phew, and went in and cooked up the steaks for the household and ate them with my Coopers.
Too lovely!
Hopped out of bed nice and early, and went to move trailer to unload it and go and do other stuff with it.
You guessed it - engine turns over, won't start.
Battery is fine at about 12.7.
Checked all the leads on plugs and coil - all fine.
Took plug leads off coil pack 2 at a time, and turned the engine over - no spark happening on all three.
Going outside to disconnect trailer lights and check some wiring although everything I have already checked looks fine.
Any suggestions other than getting a flacon or a mechanic to come on a Sunday?
I am not a good mechanic, but not hopeless either. Have a Gregory's service and repair manual. Live in South Perth WA.
