I want to do a quick and dirty imobilise of my car using the feed to the fuel pump to stop the engine from being started.
Will the ecu detect the relay as a fault and bring up a fault on the dash?
Any other quick and easy ways using just a relay that has to be energised vai a hidden switch to imobilise? I want to also have the normal red flashing LED on 1 pole of the relay when the car is imobilised too.
I intend to use a timer relay so its self setting after say 20 secs of ign off, manual switch reset to enable car starting.
