Guest 2JZ GE W58 Posted April 15, 2013 Share Posted April 15, 2013 yeah so bought a '93 2JZ GE with W58 tranny, while getting new tyres on and doing a few local bits and pieces it was starting no problem, hot or cold. so anyway i drive off yesterday on a 2 hour journey, stopped for petrol about 1.5 hours in, and car wouldnt start after. leaving me stranded. double checked nozzle before pumping for petrol (sniffed it etc) and checked after it wouldnt start too, to make sure i didnt diesel it. was a 1/4 tank anyway before fill. cranks over no problem, but no fire. initial attempt it sounded to catch very weakly so i kept cranking, but no go. thought it might be hot start issue, let it cool for 1 hour hood up, no joy. so now i cant go near it until weekend when i've limited time (plan is to check for spark to determine whether its ignition prob or fuelling prob). So.... does anyone know a common prob with supras that sounds like this? something like a crank sensor goes dodgy or that sort of thing. just want to have other things to check if ignition & fuel are ok....... thanks.

Supra Gaz Posted April 15, 2013 Share Posted April 15, 2013 I haven't heard of this before dude. Generally speaking you can't break a 2jz, especially an NA. What's te service history like? Has it been looked after? I would start with sensors and work my way up. Crank sensor is, as you said a sensible start. Are all the pulleys ok?

TheTurtleshead Posted April 15, 2013 Share Posted April 15, 2013 N/A's don't have a crank sensor. The timing is set through the distributor. Have you checked the EFI fuses in the box in the engine bay? I ha one blow on me once as it was too low an amperage. Changed to the correct 30 amp and it was fine after that.

Guest 2JZ GE W58 Posted April 15, 2013 Share Posted April 15, 2013 sorry forgot to say i checked all fuses regardless of what they were for. all good unfortunately (sounded like a fuse since it happened suddenly and not while driving along). gaz it is an ex show car but the last few years it got mistreated. to the point of backroad drifting by morons.... my restore job on it was a whole interior replacement including loom. started a good few times since that though..... something that might be related - it drives off low revs fine but flattens out bigtime thru midrange, then around 4500 kicks back in suddenly, not a power curve thing but a fueling thing feels like. maybe fuel pump calved?

reeceu Posted April 15, 2013 Share Posted April 15, 2013 With it faulting through its mid range check all the ht leads. Could be an old 1 or 2 causing some issues. Quote Link to comment Share on other sites More sharing options...

I can't remember any more details about it unfortunately, but it might give you a clue as to why your car's flat in the midrange. Quote Link to comment Share on other sites More sharing options...
Guest 2JZ GE W58 Posted April 16, 2013 Share Posted April 16, 2013 Have you checked it for error codes? not yet, i had to send the car home and im away at work til weekend. just doing research in meantime. thanks for that thread dude injection module where would i find that? follow the injector cables back to it? With it faulting through its mid range check all the ht leads. Could be an old 1 or 2 causing some issues. might just replace the lot of them, they are 20 years old. should stil start on 4-5 cylinders though?

Guest 2JZ GE W58 Posted April 21, 2013 Share Posted April 21, 2013 Seems to have been the fuel pump. Previous owner had some cable tied aftermarket pump in it and its seized/jammed. Replaced it w a stock one and works good, had to disconnect ECU for a few mins to reset it tho??? Wouldn't work before that.. Quote Link to comment Share on other sites More sharing options...
