Default Error MF2

Hi, long time not been here (is good perhaps ).
But now a question. My (very old) MF2 goes on error. With power up, the system pressurizes and the led goes off.
Few seconds later, the led comes on again!
So, what is the diagnostic checking? Only pressure? Or other things too?
Anybody knows this?

Kind regards,

Gert

It look as the system cannot sustain the set pressure, there is a small leak some where.

Thanks.

Disconnected the blue loom and switched on Ignition. For some reason the jet did not spray regularly, but after a few seconds she showed a nice continues spray.
So, I assume there was some air in the piping.
No idea why. Never had this before and remember, the kit is about 20 years in the car.

You could be right, air in the system will cause this.

Hi, anybody alive???

Anyway, my pump does not pressurize anymore.
Water is flowing to the pump, but if I power up, there is no water coming out off the pump.
I can hear her running.

How can I solve this?

manually inject some water into the pump with a syringe. I think the internal is dry.

Well, did not take much effort to succeed. :-)

Plugged power in and pump started to spit a little, what soon became normal flow.
Connected the waterlines and discovered that there is an leak at the manifold.
Pump is in the trunk and manifold under the hood in the front.

So, first I have to fix that.

But, I am still curious why the pump was dry?

Well, finally found some time to investigate the problem.

The on/off solenoid on the manifold is leaking badly.

I tried to find me some rubber gaskets that fit, but no correct size here.
Can you provide those, or a new solenoid?

I cannot find those parts on the ERL site.
