My mk 2 GTi digifant is currently abandoned in a school car park as it refused to start. It had a ropey startup to get there, but is now totally refusing to budge. Apologies for my lack of mechanical info below!
About 6 weeks ago I had a new battery as the start up had been getting worse and worse until it had "machine gun" firing attempts to start up and then everything stopped. Initially the battery seemed to sort it, but then it started getting worse again. My local garage said that it was only producing about 12.5 amps hence gradually losing charge. They replaced the resistor, but that did not help. They then changed the alternator and said it was producing around 14 amps. However, in my opinion it has still not been starting quite right since, but it always started at least. As stated above I got it going this morning and dropped my child in at school, but then it refused to start. It appears to be a very weak single crank and nothing seems to kick in. All the electrics work fine. I have been round the connections and checked terminals, but there is nothing obvious. The only thing I did note (and it may be right anyway) was the idle air control valve was "humming" when the ignition was at the first stage.
Obviously you cannot see, but is there anything obvious I should be doing/check?
Does this situation point to anything in particular?
Any help would be appreciated!
