Right peeps am really could do with help and ideas to fix this issue,
I will start at the beginning.....
Have done forged na-t conversion and car was running fine but has noise from alternator as if something inside loose, so got new alternator and during fitting I didn’t notice trickle charger wires were touching battery and the alternator power cable touched body work and caused short in loom as had little bit smoke.
Checked original loom and was damaged so decided to buy new tweaked loom from USA.
Fitted new loom and car wasn’t turning over but everything else working fine so Inazone turned up and checked all fuses and relays and have 12volts where should and all earths are good, came to conclusion that could be ecu so fitted new link G4+ ecu and installed a base map.
Now when try to start car get clicking noise from the injectors but engine still not turning over,
We bridged the starter relay in fuse box and engine turned over like it should.
But still getting nothing when turn key to start car.....
My next idea is too remove dash and remove immobiliser from loom and check any damage to wires behind dash and try again, my thinking is as now know original ecu is damaged as was not getting any noise or anything from that when tried to start car, maybe the short has damaged immobiliser aswell as ecu.
Also used the link software on laptop and am getting zero fault codes.
So any ideas of what problem could be causing car not to turn over would be massive help please?
