No Spark at coil, VT senator

[nitrowarrior]

VT 1997 Senator, ISS system has suppossedly been disabled.....anyway long story short, had to replace engine wiring harness, now vehicle will turn over but wont start. no spark at coilpack.....I am testing coil and ingniton control module tomorrow, any other ideas on what it might be....I was thinking ISS is the problem, anyone know if engine will turn over on starter motor if ISS is active??? Could this be my lack of Spark issue, ISS active and in intrusion/immobilezer mode?? any help would be appreciated....cheers

Refer to the info below on ISS. Have you tried using the black tag to disable the ISS (or has everything been removed). Not sure whether ISS will allow cranking on a VT. On my VS Calais (and Clubsport) if ISS is not disabled you get nothing, no cranking, no start. The info below is not very specific on what happens for a VT.

GENERAL
The new HSV Integrated Security System (ISS) is fitted as standard equipment to all HSV VT and VS models. The ISS is a micro-processor controlled immobiliser which automatically isolates essential electrical circuits when the ISS is armed and accessory or ignition ‘ON’ is detected. The immobiliser is disarmed using a valid ignition key code and uniquely coded black tags which contain a small chip incorporating specific codes. The HSV ISS has been improved for the VT range of vehicles. The vehicle no longer requires use of the black ISS tag each time the vehicle is started. The ISS records the ignition key code and will disarm when a valid vehicle ignition key is detected at the key slip ring. Up to seven vehicle ignition keys and seven ISS black tags can be assigned to the vehicle if required.
NOTE:
IF THE KEY-HEAD BECOMES UNSERVICEABLE AND FAILS TO DISARM THE ISS, THE ISS MAY BE DISARMED USING THE BLACK TAG UNTIL A REPLACEMENT KEY IS INTRODUCED.
INTRODUCING NEW KEYS
A red MASTER TAG is also supplied with each ISS. This tag is used to place the ISS into `Learn’ mode: touching the red tag to the status monitor (located in the glove box) will cause the LED flash rate to increase which indicates that learn mode is operative. In this mode, codes for lost tags/keys may be overwritten and new keys/tags may be introduced as follows:
With the ISS in learn mode, insert ignition key and turn ignition switch to ‘IGN ON’ position. The status monitor will change to indicate ignition key code has been successfully stored (LED goes off). ISS will return to normal mode. Retouch red tag if more ignition keys are to be introduced.
With ISS in learn mode, touch new black tag to receptacle for approximately 2 secs. Status monitor LED will change to indicate key code has been successfully stored (LED on). ISS will return to normal mode. Retouch the red tag if more black tags are to be introduced.
NOTE:
THE ISS WILL RECOGNISE SEVEN KEY AND TAG CODES. IF A TAG OR KEY IS LOST, THE REMAINING/NEW CODES MUST BE ENTERED SEVEN TIMES TO ENSURE THAT THE CODE FOR THE LOST KEY OR TAG HAS BEEN OVERWRITTEN AND CANNOT DISARM THE ISS.
NOTE:
RED TAGS MUST BE STORED IN A SECURE LOCATION REMOTE FROM THE VEHICLE. DO NOT STORE RED TAG IN VEHICLE. LOSS OF A RED TAG WILL REQUIRE REPLACEMENT OF THE ISS SYSTEM IF KEYS ARE LOST OR DAMAGED

SERVICE OPERATIONS
If an ignition key has been damaged and does not transfer a valid code, the ISS may be disarmed by touching a valid black tag to the status monitor: this will transmit code to the BCM and enable vehicle start No periodic servicing of the ISS is required and no additional information is provided or available on the system. HSV dealers are not authorised to carry out any servicing operations on the ISS system. All requests for information and/or assistance are to be forwarded directly to the Service Manager at HSV. Before making this request and at any time that correct operation of the ISS is suspected, the following functional check should be performed:
Check ISS status monitor (located in glovebox) to ensure ISS is in armed mode—i.e. slow flash
Place a piece of tape over the ignition key slip ring contact to break the electrical circuit between ignition key and ignition barrel slip ring,
Turn key to start position—vehicle should not start.

Not ISS......I have fully Disabled ISS......Give me time and I will post a How to....But ISS is gone not the problem......
Still no spark at coil pack.........I am have trouble getting the Ignition Module tested.....Coil is cracked, so will get a new one.......Will post further once i finish diagnostics, going to take the Ignition Module and Coil off my Running Clubby, and put it onto the Senator, see if we get life.......If i get life, new Module and coil.............any other ideas on what could be the fault??? All fuses and fusable links have been checked cant think of any other eason why no spark at coil.
