Fuel pump, Is it dead? Options

[VINCE]

I was working on my FI 30 minutes ago. It is a L-jetronic (1.8L from 75).
I have changed some fuel hoses few days ago. My engine didn't not run because I had no fuel in fuel hoses!!

So I tried to localise the problem: I ran the pump by pressing on the AFM flap. The pump worked 10 seconds and died.
Now, when I press the AFM, I can hear 2 'clacs':
- 1 from the relay (close to the battery) => OK
- 1 from the fuel pump but the pump does not run

Is my pump dead?

What should I do?

It is my daily driver: I need a solution, please help me.

Thanks

I'm not familiar with the L jet but I would first check voltage at the pump. With the d-jet, the pump can be run by jumpering across the relay and voltage then can easily be checked. 2nd, make sure that fuel is getting to the pump- blockages in the filter, tank, lines? The d-jet pump is very reliable, does the l-jet use the same pump?
good luck

Finally, I found that my fuel pump is OK. In fact, I inversed + and - and it started again. (IMG:style_emoticons/default/biggrin.gif)

I also fond what was wrong on my FI: my fuel regulator does not permit fuel to flow (IMG:style_emoticons/default/sad.gif)
I have pressure at the inlet but not not at the exit. So I temporarply made a by-pass of the fuel regulator.
The fact that my fuel regulator does not permit fuel to flow is a little strange because it seems to be new (see picture).

My question is: Are fuel inlet and fuel exit correctly connected to me fuel regulator? See the picture enclosed (that was the way my fuel regulator was connected to fuel hoses).
