guys just changed the knock sensor on my ek9 when i reconnected the battery the arlam went off as it always does to pushed the lock/unlock key to stop alarm. then went into the car and went to start the engine all lights on dash came on as per and fuel pump primed. when i turned the key... Zip and all the power died it never even tried to kick the starter. so turned the key back and locked unlocked the car to try again and nothing. checked the fueses and all seem good and getting power. i have a clifford g5 alarm in the car could it be the imobiliser ? i push the unlock button on the fob and get zilch no even getting central locking
 
Could be mate. You still getting dash lights? Check your battery connections and earths.
 
Done that just now there fuse is fine. I don't even have paperwork or any codes for the alarm hope the receiver for the fob hasn't fried that's all I have for the alarm. It's a g5 concept 650 mk2 if anyone knows anything about them
 
That's ****, I was gona say ignition switch mate , but havin no hazards is strange? Seems battery fuse is fudged?
 
Check your battery earth, had the exact same problem and the battery wasn't earthed properly!
 
Ok guys came home connected the battery the alarm went off to silenced alarm with fob and car started first shot. Next problem is I had just replaced the knock sensor and I'm still getting cel code 23
 
Check wire for knock sensor at ecu ,and make sure it's not shortin out .
 
Check wire for knock sensor from loom I'm earthing off battery and test light isn't lightning up when I touch the knock sensor plug. Is this my problem
 
I would check the wire differently mate. Disconnect ecu and find pin for knock sensor input, disconnect knock sensor plug and test for continuity. If it's there take a not of resistance. If it's not there check connections on the connector plug that joins the engine loom near the battery.
 
I'm hopeless with electronics mate will try my best though desperate to get back out in the car
