Hi welcome all,
I just purchased a c70 t5 gt convertible with 42k on the clock.
I brought it off my dads friend which has been sitting in his garage for the past 3yrs. I've had the car 3 weeks an always started till the other day, an it now clicks when it goes to start I've had new starter new battery checked the relay and the 50a fuse all look fine even started it after takin relay cap off.
So didn't start mon went to it yest fired straight up. Went to it today clicked again 15times then started used it for 3hrs with starting several times? Can't be to much. Can any of you people help me at all?
Also plugged it into obd11 no codes at all?..
Regards

 

My 1998 C70 coupe did the same. Check all wire connections to ensure all are tight & signs of arching. I had to replace the ignition switch. Most auto parts stores will check complete starting system for free!
