Scully Posted January 22, 2015 Share Posted January 22, 2015 (edited) So details first Fully serviced with 62k miles 2007 HR fault codes P0000 nil What happened: went to tesco, came out and would Not turn over - starter gave one dieing groan for a second and stopped. What I did: suspected battery although it was showing 12v, jumped off another car - no difference Bought a new battery no difference Recovered back to my drive Next: starter off and tested, tested OK Tested continuity in the cable from the battery+ to starter, all good (very minor surface corrosion) Checked ignition fuse next to the battery, still intact At this point I'd like to say: All my keys still unlock and lock the car remotely and extinguish the immobiliser led Fuel pump can be heard to prime Upon key to start, nothing at all from the starter Now I'm suspecting maybe continuity in the cable from the ignition system? Blown relay? Not sure how likely that is Another fuse I'm unaware of? Any suggestions are welcome Edited January 22, 2015 by Scully Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted January 22, 2015 Share Posted January 22, 2015 did you test the earth strap on the battery for continuity ? is everything else ok, lights etc etc ? Quote Link to comment Share on other sites More sharing options...
Scully Posted January 22, 2015 Author Share Posted January 22, 2015 Yeah earth is fine, and all lights work ok Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted January 22, 2015 Share Posted January 22, 2015 does the engine turn over easily by hand ? push start Quote Link to comment Share on other sites More sharing options...
AliveBoy Posted January 22, 2015 Share Posted January 22, 2015 Have you had any oil lights recently? If the engine seized, everything would prime, but no response? Quote Link to comment Share on other sites More sharing options...
Scully Posted January 22, 2015 Author Share Posted January 22, 2015 I don't think the engine has seized but I'll try and turn it over by hand, I guess it's just a case of getting a wrench on the crack? No warning lights of any kind On the electrical side the 40A fuse infront of the battery and the 15A behind are fine, just need to find a diagram to show which relay is ignition.

AliveBoy Posted January 22, 2015 Share Posted January 22, 2015 have you tried bump starting it? Just make sure you turn off the traction control first. If it's an intermittent issue with the starter motor, bump starting will bypass that Quote Link to comment Share on other sites More sharing options...

Scully Posted January 22, 2015 Author Share Posted January 22, 2015 Yeah tried bumping it in tesco car park, although I didn't have traction switched off, would that have made much of a difference at 3mph though? Quote Link to comment Share on other sites More sharing options...
AliveBoy Posted January 22, 2015 Share Posted January 22, 2015 when the engine cuts in, the wheels will kick a bit as you'll be full throttle in 1st and the traction could try and kill it. I don't know for sure, but I'd expect it to. Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted January 22, 2015 Share Posted January 22, 2015 Yeah tried bumping it in tesco car park, although I didn't have traction switched off, would that have made much of a difference at 3mph though? just put it in 3rd gear and rock the car backwards and forwards, you should see the engine turning/moving 1 Quote Link to comment Share on other sites More sharing options...
Scully Posted January 22, 2015 Author Share Posted January 22, 2015 I've got it on stands atm so just stuck a bar on the crank, and it's turns fine... I honestly think it's something to do with the ignition system. Just got my sister to try and start it whilst I was measuring voltage For reference the battery measured at 12.47v As mentioned earlier the starter worked when tested with another 12V battery, as the main feed and acting as the feed from the ignition. When measuring just now the starter was only receiving 3.36v through the ignition feed. I'm no expert my I'm sure that is meant to be 12v. I don't think 3.36v is enough to activate the circuit in the starter to allow the main battery feed through Quote Link to comment Share on other sites More sharing options...
SkylineV35 Posted January 22, 2015 Share Posted January 22, 2015 I know this sounds stupid and I dont mean to be, but is there fuel in the car? I say that cause one of my mates said car wouldnt start and after checking absolutely everything realised is fuel gauge wasnt working and he had no fuel Quote Link to comment Share on other sites More sharing options...

Scully Posted January 22, 2015 Author Share Posted January 22, 2015 Yeah there's fuel, I have a feeling I'm going to have to get some wiring diagrams and work my way through Quote Link to comment Share on other sites More sharing options...
GIXXERUK Posted January 22, 2015 Share Posted January 22, 2015 Yeah there's fuel, I have a feeling I'm going to have to get some wiring diagrams and work my way through I had a similar issue on another car and it took a while to find but it was a cable to the starter relay that had got water inside the casing and corroded the wire ! no outward signs of any problems, just took ages checking continuity until i found it.. problems can be that random good news it turns over 1 Quote Link to comment Share on other sites More sharing options...
zxrob Posted January 22, 2015 Share Posted January 22, 2015 12v wont start it, battery needs to be putting out 12.6 volts min Rob Quote Link to comment Share on other sites More sharing options...
Scully Posted January 22, 2015 Author Share Posted January 22, 2015 Are you sure, my brand new battery wasn't putting out that much from the shop But any, with all my tinkering somehow there is now 12v through the signal cable on start, and it turned very slowly. So I'm going to go ahead and change the starter and see what happens.... Quote Link to comment Share on other sites More sharing options...
a2orry Posted January 22, 2015 Share Posted January 22, 2015 The low voltage at the trigger wire would make me think ignition switch but I would also check the switch at the clutch pedal. Quote Link to comment Share on other sites More sharing options...
Scully Posted January 22, 2015 Author Share Posted January 22, 2015 Clutch pedal switch is fine. Also had a suggestion that the BCM may have failed, that will be next on my list Quote Link to comment Share on other sites More sharing options...
a2orry Posted January 22, 2015 Share Posted January 22, 2015 What you've just said brings back vague memories of Zmanalex supplying a BCM to someone with a similar problem. Quote Link to comment Share on other sites More sharing options...
Scully Posted January 27, 2015 Author Share Posted January 27, 2015 Starter changed and exactly the same... Been reading a few people with cam position sensors at fault but they all have relevant code up. Quote Link to comment Share on other sites More sharing options...
