    Default 1FZ-FE fuel injection type

    I am contemplating converting my 1997 FZJ80 to injected LPG but firstly I need to know whether the type of fuel injection it has is sequential or multi-point. Can anyone tell me what year Toyota switched from MPFI to SFI and if my model is SFI?
    It's a 1997 FZJ80 1FZ-FE 4.5l petrol
    Let me know if you need any more info.
    Cheers,
    Alan.

    a quick google search suggests that it was the prior 3F-E motor that had MFI and the 1FZ-FE always had SFI. There was an update to the 1FZ (circa 2000) where they changed from a dizzi to waste-spark ignition and also from MAF to MAP sensors.

    Thanks for the reply. That confirms my research too. My workshop manual wiring diagram shows separate wires from the ECU to each injector. It does cover many years tho so I wasn't sure.
