The ISBN number of the Haynes manual I have is 'ISBN 1 85960 450 1' It is the UK Haynes manual for all the 190s from 1983 to 1993 (A to L registration in the UK). I got it from euro car parts (http://www.eurocarparts.com
Yesterday, I actually managed to start the beast (after about a minute of cranking with my foot on the floor - apparently it is an anti-flood mode the computer goes into....). I took it out for a spin and all seemed well. I just hope she starts again this morning!
Thanks for everyone's help, I'll be back if it doesn't start! lol
