Spike3.0 Posted September 2, 2013 Share Posted September 2, 2013 (edited) I'm hoping to narrow down on what's going on with my Supra. I bought it a few weeks ago and a none runner, and after a bit of messing around and the help of fellow member russ-unsworth we got it going. Currently the car will turn over but won't fire up - unless easy start spray is used. When the car does run the engine is rough and it sounds like the injectors aren't running right. I've since found out that the previous owner replaced the injectors believing this to be the fault but it didn't make any difference. They think it was something to do with the wiring? Before I go off and buy any un-needed parts does anyone have any ideas? Also I couldnt find a NA wiring diagram, a link would be great! Cheers!

Spike3.0 Posted September 3, 2013 Author Share Posted September 3, 2013 Anyone got the NA wiring diagram, I couldn't find it apart from faulty links. Quote Link to comment Share on other sites More sharing options...
David P Posted September 3, 2013 Share Posted September 3, 2013 The Club list only has EFI & Ignition for 2JZ-GE VVTI. http://www.mkivsupra.net/vbb/content.php?67-EFI-Ignition-(2JZ-GE-VVTI) If what you seek is not there, I'll take and post you some pics from the Manual.

Ian C Posted September 3, 2013 Share Posted September 3, 2013 Could be ignition timing very retarded? Quote Link to comment Share on other sites More sharing options...
Spike3.0 Posted September 3, 2013 Author Share Posted September 3, 2013 Thanks for the link, much appreciated! Any photos would be great too, cheers The timing looks good, I had one of the members on here check it and everything seems ok with that department.

Fly Posted September 3, 2013 Share Posted September 3, 2013 stupid one but are you sure that the injectors are high imp 330s and a cock up there has not been made? Quote Link to comment Share on other sites More sharing options...
David P Posted September 3, 2013 Share Posted September 3, 2013 (edited) Here's a couple of pics. Ignore my blue scribbles and don't look for a variable resistor, because when Mr T. wrote the Supra Bible he forgot that it doesn't have one. (If anyone has a link to non VVTI GE EFI & Ignition please send it to Steve, both Club archives and members would benefit from the info.)

Nodalmighty Posted September 3, 2013 Share Posted September 3, 2013 It's not something silly like the HT leads being on the wrong plugs? Lyndon. Quote Link to comment Share on other sites More sharing options...
