Guest suprageek Posted September 29, 2013 Share Posted September 29, 2013 (edited) Was driving my supra this morn and it died, (tt bpu auto 1993) it's trying to fire up but refuses to start, tried the engine diagnostics and I am getting a steady flashing light, listened to the fuel pump and it sounds like its priming when I try and start the engine, checked spark plugs all ok, swapped around the Eli relays and they all seem to work, anyone any ideas please on what the problem maybe?

Abz Posted September 29, 2013 Share Posted September 29, 2013 Did you manage to get an error code? Take it battery is good? Or you driven it recently? You got plenty of fuel in the tank? Quote Link to comment Share on other sites More sharing options...
TheTurtleshead Posted September 29, 2013 Share Posted September 29, 2013 Map sensor plugged in properly? Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted September 29, 2013 Share Posted September 29, 2013 Yea no error code just a steady flashing light, I was driving it this morn and it just died and refused to restart, where is the map sensor James? Thanks Quote Link to comment Share on other sites More sharing options...
TheTurtleshead Posted September 29, 2013 Share Posted September 29, 2013 Intake manifold… It has a little vacuum hose into the bottom of it and a 3 pin plug going into it. Give it a try. long shot but it won't run without it. Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted September 29, 2013 Share Posted September 29, 2013 Would that not show up on the error code James? Quote Link to comment Share on other sites More sharing options...
Swampy442 Posted September 29, 2013 Share Posted September 29, 2013 Get a paper clip, and in the diagnostic port connect to terminals marked B+ and Fp, try to start it. If it works its the fuel pump ECU. Be careful because the clip gets quite hot! Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted September 29, 2013 Share Posted September 29, 2013 Thanks for that swampy I'll let you know how I get on tomorrow Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted September 30, 2013 Share Posted September 30, 2013 Not that, there's no spark from the plugs though so this must be the problem, just have to find out why now Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted September 30, 2013 Share Posted September 30, 2013 Any ideas why no spark? Quote Link to comment Share on other sites More sharing options...
Gpro Posted September 30, 2013 Share Posted September 30, 2013 Ignition amplifier? Maybe Quote Link to comment Share on other sites More sharing options...
marc_p Posted September 30, 2013 Share Posted September 30, 2013 Would that not show up on the error code James? No, MAP sensors won't usually log an error code. Anyway, if there is no spark, as someone else said, check the ignition amplifier, had it happen to mine a couple of years ago where it hadn't been plugged back in properly and lost connection.

Guest suprageek Posted October 2, 2013 Share Posted October 2, 2013 Hi my diagnostics says this has failed, is this the igniter or something else? Thanks Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 2, 2013 Share Posted October 2, 2013 I thought I recognised this, you've already got one in tech that's active and spammed it with another one that I've closed. Stick to one active thread Quote Link to comment Share on other sites More sharing options...
Ian C Posted October 2, 2013 Share Posted October 2, 2013 Also, what diagnostics told you that, seeing as that phrase isn't mentioned anywhere in the diagnostics code table? - - - Updated - - - Threads merged Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted October 2, 2013 Share Posted October 2, 2013 Was an auto electrician sounded like bull shit to me too mate, I've an igniter coming so I think that's the problem Quote Link to comment Share on other sites More sharing options...
Tyson Posted October 2, 2013 Share Posted October 2, 2013 You might get more help if your thread title actually reflected the problem you have ........ Quote Link to comment Share on other sites More sharing options...
Guest suprageek Posted October 5, 2013 Share Posted October 5, 2013 Right I got an igniter and it's still not running, I'm thinking it maybe the crank position sensor but there is no error code showing when I bridge the terminals on the engine diagnostics port just a steady flashing light, could it maybe still be this even with no error code showing? It is backfiring instead of starting up, I've read previous threads and it could be a number of things ecu, bad earth, coil packs, plugs, cam pos sensors, crank pos sensors, has anyone any ideas I'm lost!
