My mates got a 1999 uk and it appears the sigma alarm is switched off BUT it wont start on the key. If we bypass the relays and wire the pump direct it works. No EML on, no clicking in the dash.

We've tried new relays, no joy so assume its the crappy sigma which he wants to remove/bypass. Funds are low so he cant afford to pay someone to remove/replace it. For the time being we've bypassed the wiring and run direct from the boot to pump via the sidelights.
