start wont start again

[klm182]

just washed the car,, wouldn't start... few weeks ago broke down, aa man pulled a wire back on the engine(starter motor) he said the connected needs checking..when for mot last week, asked garage to check starter,,
said its fine(don't no if they checked...
I just put hand down back engine felt a wire with a sleeve on, you can move ,I pulled it,then it started..
anyway how can I get at the starter motor? take wheel off and the wheel arch? if I jack it up abit could I get at it?
don't wanna take it to the garage again..

hopefully I will get some advice from this section...
car not start....

The starter motor is behind / underneath the manifold . There's a bolted connection and a small exciter wire which just pushes onto a spade connector .

its in a pig of place really
