OK so had the engine out to fit the turbo kit. Everything is back together but its not cranking over. Here's what I have tried so far.

 

Fully charge battery

Check constant 12v to starter

Jump relay to checker starter and it cranks

Checked plugs into ecu and fuse box are secure

Checked fuses in drivers fusebox ST and IGN all good.

Checked grounding to starter

Checked 12v when ignition is turned at starter wire at starter motor and I'm not getting 12v... so I assume this will help solve it..

Tried to check the relay but I'm.not 100 percent sure on that one. But I did swap the fog relay into the starter and that seemed to fit but car still didn't crank 

Any ideas as I have run out!!

 

One other thing is the previous owner installed a Rightclick immobiliser, but I think this just cuts the fuel as if I opened the car without deactivating the immobiliser it would just crank but nor start.

OK so after spending the day with a multimeter and checking connections I had plugged one of the engine harness plugs into the wrong socket. Grey into white.... idiot. Still starts up now!

Must have looked at it about 10 times!
