How did he clean them? I hope he didn't use a blowtorch

As per pm, check the alarm install. If he tapped into the wiring at the ecu and has used power from the injector power wires or similar it can cause this

yer plug must have fouled up wen he turned the car on and off for the alarm but all good now and he did a top job i love the new alarm and he was a top bloke made sure everything was 100% before he left
