not much to update as made a big c@%k up.
as stated above, had a huge problem with the fuel pump.
the car has been back fireing lack of power etc
so changed cambeltand water pump, maf, rotors caps, still no joy so scoped every sensor with no fault. (£700 later and way to many late nights)
so stupid toyota didnt put a fuel pressure tap off to hook a gauge on, so I kept looking at something else.
I made my own way to measure fuel pressure it only had 10psi.
so pulled pump out and found a split hose.
AN connectors ordered if I remember to take pics, pics to follow
