i've just got a 1996 seat toledo which has an AAZ in it to use as a doner for the engine, but after looking at the diesel pump and comparing it with the one on my SB i'm a bit confused. on the SB pump theres only one wire coming from it which goes off to a live. although on the AAZ there are four wires coming from it, 2 come from where the one wire normally goes although it has some kind of cover over it, and 2 from the center of the four fuel pipes (theres just a nut there on the SB).
heres a pic of what i'm on about...
other than that the pump looks just the same as my 1.6 one :?
Its the equivelent of the needle lift sensor on a TDI, it measures when injection commences and dicks about with the pump timing via the solenoid on the bottom of the pump.
It is basically semi electronic control.
can i bypass or get rid of this?
Practically yes, ideally no.
I have run them without, they work, but it's there for a reason.
The control unit is connected to a vehicle speed sensor as well as loads of other things.
I have fitted them in T3's and snipped with wires back when I have had no option but most people find another AAZ pump without all the electrical gubbins and fit that instead.
maybe have a word with TinTin or Giles and see what they suggest.
would fitting my 1.6 pump be an option? would it suffer performance wise?
dude that thing is nasty looking clean it up
so could i just get around this by fitting my 1.6 IP?
