Thanks sparky ive messaged you
Pete it was turning over as normal but just wouldn't start ( same symptom you would get if you had flooded the accelerator..I had to call the AA out, he located it under the back seat and checked all the wiring feeds were working to the pump,he then knocked it with a hammer and as i turned it over BINGO it started..
Seems a easy enough job to do due to to the excellent engineering location from lexus..
Are you having the same problem?
