Hi,
My S3 with a defender 2.5 petrol is an absolute sod to start hot - from cold it'll go within a few seconds with a bit of choke. Hot it can be virtually impossible to restart - 30-40s cranking then it will go if you are lucky...
After being unable to start it at a PnP site over the weekend, I got a bump start, where it fired literally within 3 feet of being pulled. Playing around later on, if you get it spinning over, drop back from start on the key momentarily, it'll go (so it's firing while the engine is spinning over under not a lot of starter load) - the only thing I can think of is that the starter is stealing all the juice, and the series wiring isn't giving enough to the coil to give a good spark..
It's running a new coil (which doesn't get hot), a simon BBC electronic dizzy and other than that runs perfectly. Timing, mixture etc are all good.
Has anyone else come across anything similar? I was thinking of maybe running a permanent +ve feed to the coil direct from the battery switched by a relay from the original coil feed to see if it helps...
