Thank you all. Ok an update haven't been able to work on car because of the rain, and I have no garage. I have been looking online at videos and I really don't have the tools needed yet..
the rigmaroll it takes is a bit daunting to say the least. and recoding is necessary
guys, on one video a guy changed his starter motor only to find it was the sensor UNDER the damn starter, so the starter had to come out again.
so how do I sort this (money pit ) out
my test is due in 6 days,( need a good code reader ) so might have to let the garage do it which is a frightening thought,
As an afterthought, would a code reader pin point the exact problem? I have worked on my cars in the past but then they didn't have a damn computer in them. will get back later.
