'90 200T starting issues

[Geraint Lloyd]

What is the car actually doing or not doing?
is it hot start or cold start or both that is a
problem.
Stock or modded ECU?

I have a BTDTASFTTCACOTI with an 89 MC2 200TQA cold
start problem that
turned out to be a dead ECU (or ECU component that I
do not have the
skills to trace, but did have a spare ECU)

the CSV gets 12v all of the time and has the earth
switched through the ECU

when I had my drama the guys suggested a push button
(on the earth) to
fire the CSV.

Are you sure that you have a Thermo Time switch?
AFAIK (not very much sometimes) the MC2 / MAC 14 ECU
doesn't have one

Claimed On The
Insurance.
