R33 GTST no start

A friend of mine has a R33 GTST SERIES 2 with a Haltech platinum pro ecu.

The back story and whats been done.

The car doesnt get driven much so often had to be jump started as the battery was flat. One day they went to jump start it and no go. The motor cranked but didnt fire. 

After some testing we found there was no spark, signal to fuel injectors or fuel pump.

The ecu was sent back to haltech for testing. They upgraded the power supply and a few other things but found bo problems. When we got the ecu back we plugged it in and hoped for the best but still no go. 

It has an aftermarket immobilizer which im thinking is probably the next thing to look at unless anyone has some other suggestions

Thanks

I would also be looking at the immobiliser. You could also check out the ignition fuse and relay. Google will help you for the location of those.

All fuses have been checked and relays like the ignition and fuel pump have been bridged with no success

Immobiliser it is then. I recently had an issue with mine. An internal relay inside was jammed. I found the box and tapped it with a screwdriver and it came back to life.
