i belive there isnt a filter as mentioned above , anyhow i had a look at relay number 6 in the main fuse box which is the main engine relay ,didnt show any sign of burning or smell, but i thought to be sure and changed it for a replacement i had and this morning she fired straight up so hopefully this was the problem ,
will see what happens over the next few days before i am confident its fixed but it does look promising
indeed wammers it is relay 19 which is main engine relay according to the fuse box lid , i may have been somewhat misinformed by this diagram i found online and not reading the key , where 6 in the picture is actually 19
