Alastair12 Posted May 23, 2005 Share Posted May 23, 2005 Problem with starting my Caterham. I have got a Superlight R with the 1800 K series in it.Was at Brands yesterday, had a spin and then the car would not start again. When you push the starter button there is a click at the ECU but nothing else. I have checked all visible wires and connections and nothing seems obvious. Battery is fine. Any thoughts or ideas is the long and short of it? Thanks in advance Alastair. Link to comment Share on other sites More sharing options...
Dickie Normuss Posted May 23, 2005 Share Posted May 23, 2005 Maybe the inertial cut off switch 🤔 I seem to recall others saying there is a "reset" type button om the ECU Could be talking trash, someone with a brain will be along momentarily Seek forgiveness, not permission. Rules are for the interpretation of wise men and the obedience of fools. Link to comment Share on other sites More sharing options...
Paulo Posted May 23, 2005 Share Posted May 23, 2005 Does it start when cold ? If so your starter motor doesn't like being hot and it's Brise time. Link to comment Share on other sites More sharing options...
Alastair12 Posted May 23, 2005 Author Share Posted May 23, 2005 No it is not starting at all whether hot or cold. Link to comment Share on other sites More sharing options...
oilyhands Posted May 23, 2005 Share Posted May 23, 2005 Sounds like the inertia switch to me, it should be mounted on the bulkhead near or above the ECU, it is small (3" x 2" x 2") and has a rubber plunger/cover on the top. Dave Link to comment Share on other sites More sharing options...

F355GTS Posted May 23, 2005 Share Posted May 23, 2005 Worth checking the ECU fuse, if it's a 20amp change it to a 30amp Mark Link to comment Share on other sites More sharing options...
mav Posted May 23, 2005 Share Posted May 23, 2005 also make sure that the connector on the bottom of the inertia switch is located correctly. If it is at all loose, it will cause the car to not start... Link to comment Share on other sites More sharing options...
Grim Reaper Posted May 23, 2005 Share Posted May 23, 2005 Can you hear the fuel pump prime when the ignition is turned on (before turning to start)? The pump should be heard to prime, then stop. It will start running again once the ECU has determined the engine is rotating. No priming=no electrical supply to pump. Look for connectors off, inertia switches tripped, fuses blown etc etc. Link to comment Share on other sites More sharing options...
John Vine Posted May 24, 2005 Share Posted May 24, 2005 Alastair, Sorry I wasn't able to offer more help! I think we confirmed the ECU fuse was OK, the fuel pump was priming OK, and that there were no obvious loose or unconnected wires. We didn't check the inertia switch or its connections, but I think Merrick did check the reset button when we ran the car down to his garage. So, my prime suspect is the immobiliser circuit, especially as the indicator light was behaving so oddly, with the inertia switch connection a close second. Hope you get it fixed, and do let me know what Redline say. JV Link to comment Share on other sites More sharing options...
