madmunky Posted January 24, 2008 Author Share Posted January 24, 2008 Done so far 1. Check Spark plugs for Spark 2. Check fuelling up to injector rail 3. Check Alarm 4. Replace Coil pack connectors 5. 12v Fuel Mod 6. Engine earthing wire 7. Battery recharged 8. Checked ECU for error codes 9. Checked voltage on crankshaft sensors Thing that's the list so far, as you can hear from the sound clip it sounds like its just about to start Quote Link to comment Share on other sites More sharing options...
simbasupra Posted January 24, 2008 Share Posted January 24, 2008 No they are not shown on the picture, the numbers on the end of them 10737-11062 & 11428 So i think the part numbers should be 90980-10737 90980-11428 Can anyone confirm this I would say those part numbers are right going by this thread http://www.supraforums.com/forum/showthread.php?t=238783 Quote Link to comment Share on other sites More sharing options...
madmunky Posted January 25, 2008 Author Share Posted January 25, 2008 Cheers mate, anyone got any ideas on what could be wrong with the car? Quote Link to comment Share on other sites More sharing options...
Marty Posted January 25, 2008 Share Posted January 25, 2008 Fuel pressure?? maybe your regulator is fooked Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 25, 2008 Share Posted January 25, 2008 Check the reference hose is on your FPR okay, and also check the reference hose is on the MAP sensor as well. Either of these missing will cause a huge overfuel. In fact check all the plumbing that comes off that as well, make sure you have no split hoses or hoses popped off. Try starting the car with the throttle flat to the floor, and keep turning it over rather than stopping as soon as you hear something catch (like in the wav you uploaded) -Ian Quote Link to comment Share on other sites More sharing options...

Lees also pop round tonight to take a look so will keep everyone updated too I want my poor car back on the road Quote Link to comment Share on other sites More sharing options...
Ian C Posted January 25, 2008 Share Posted January 25, 2008 Dunno about it "sounding" rich but it "thinks" rich It's obviously delivering some fuel as it catches, and I've seen a 2JZ start with only 2 cylinders working, albeit not very well, so that rules out one or even two individual injectors, sparks, cylinder compression etc. being at fault. The whole ignition system must be working as you've found a spark and again, it catches. It'd have trouble starting if it was too rich or too lean, but a rich mixture is much much easier to have happen due to things failing - like the popped off hoses making the ECU think it's at full non-boosted load. It's also a failure mode that wouldn't log a fault code. The fuel pump going suddenly very weak could cause an issue BUT, I've seen that before once as well. As you are seeing fuel in the pipes, the pump spinning up on key-off should put enough fuel in the system to deal with the relatively light loads of start and idle, so it should catch, idle, and then die if that were the case. So my money is on it being too rich The wide open throttle starting test might let it start if it's too rich, so it's worth a test although it is now possible your plugs are fouled to the point that it won't start anyway so they may need a clean first. -Ian Quote Link to comment Share on other sites More sharing options...

HadeS Posted December 4, 2010 Share Posted December 4, 2010 Bumping the thread as I have overfueling as madmunky but after replacing coolant sensor there is still the problem. What else can I do to make it running right? Quote Link to comment Share on other sites More sharing options...
HadeS Posted December 5, 2010 Share Posted December 5, 2010 update on that: fault injectors where causing overfueling. Quote Link to comment Share on other sites More sharing options...
