Hi all, my daughter has a 2009 500 sport 1.2, which up until a few days ago has been faultless, started at first turn of the key, I got a call to say my car wont start its just dead, when I had a look I thought she'd just left the interior light on and battery had gone flat, so bump started the car and all seemed fine...
left it running 10 mins, turned off and attempted to start again - same again, this time accompanies by a whole series of fuel cut off and ABS warnings, bumped again and took for a 10 min drive - same again.
After checking all the fuses and starting to search common faults, and came across the issue with the body to gearbox earth strap, tested by putting a jump lead from engine to battery negative - all the warnings went away and car cranked and started eventually.
have replaced the earth strap with a heavy duty earth cable, and the car now cranks much better, but starting takes 5-10 seconds. I've gone through and checked the plugs - all in good condition, other than not being tight and unscrewing 2 of them without a ratchet.
I've now gone through checking for any other bad earths and all seems ok - but the car is a real pain to start again anywhere between 5 and 10 seconds of cranking before it finally fires up. Has anyone else experienced anything similar? the only other thing that i appear to have found whilst searching is the car may need a software reflash - could this have become corrupt with bad earth?
EDIT: I have hooked it up to a Snap On code reader, nothing really obvious just 2 faults ABS: C1215 Brake Switch and Body Computer B1010 Brake Switch, none of which i would expect to give the starting issue
