Hi Zoltan.

I'm not overly familiar with this part but here's my thoughts......

Looking at the Bentley wiring diagram, it looks like the cold start valve
is controlled by a timer; the timer appears close the positive side of that
circuit. So, I don't think this valve gets pulsed open, closed. (so maybe
the term "5th injector" is misleading?) Once the timer is turned on,
positive to the valve should be constant. So, the test light should not
flicker.

Did you use the test on P. 24.6 in Bentley?

Maybe the cold start valve timer has failed?

If it was me, I'd clean the 50 connection at starter motor, clean the
connections at the fuel pump "double relay".

Neil.
