TJ failure

Yes the flow has been checked, it is low ... but what is the link between the timing on the back and the fuel flow?

I have already changed the "rampe de moulinet" ... but the problem persists; we change the fuel pump

(From Google)
 
So after my pump change, everything is running
When I took it apart ........ HORRIBLE
The brown sieve, all frayed ... the filter - when I tilted the pump - let gasoline flow ... black, and the tank was mined with filings .... I think the pump is HS

I cleaned the tank thoroughly, reassemble this DELPHI pump, suddenly I changed the injectors by 4 holes

It turns very well
