The fulepump only starts sometimes, and if it starts it stops runing after a few minutes. The pump itself seems to be ok!

 

ok so whats the question?

 

Well, something most be wrong and I need to know what. I can't use the car right now. So the question is: What can be wrong and what can I do?

 

if U have no clue about what U are doing or have no tools to figure this out I would let a professional take care of it. This forum is for people that can at least tinker with things and have a mechanical mind set.

 

ASD-system ok.
Fuelpump relay ok.
Wiring ok.
Fuelpump is removed for cleaning and control. I don't got the vcalues for this specifik pump but thats not a big problem. But the question remains. Have I missed anything. I'm not that good att english so it's rather difficult to explain things sometimes.

 

if the 2 relays and the wires are ok ten that leads to just the fuel pump itself is bad.
Can u jump the fuel pump relay and get power to the pump?

 

Yes, i've done that. The pump goes slover and slover and then it stops. Sounds like it works heavier and heavier. I'll see if I can clean the inside. If that doesn't have any effect I suppose that I nedd a new pump/pumpmotor. Do you know the electric impedans of the pumpmotor?
Thanyou for your patience - it might be esyer if you learn swedish!

 

replace the whole pump assembly

 

I'll do that tomorrow. Today I took out the pum,p from the pump modul and I gess that the coil (?) is broken. I'll get back after replacing tomorrow.
