My Discovery is having a problem. First the key would not turn to the removal position unless the power was cut, we installed a switch to enable that this worked for about a year then the ignition would not always start the vehicle, sometimes it would start fine then other times nothing, not a click or anything unless wiggling the key numerous times. We have now replaced the entire ignition module (1000.00 part later) and it is still doing the same thing. Any thoughts? We have checked it is in park etc. pulling out our hair a wee bit love my truck just want it to start reliably. Otherwise everything else is great!
