Guest Bazsupra Posted December 4, 2009 Share Posted December 4, 2009 Hi guys, iv looked throught the previous threads and to no avail, Basically i had my supra (single turbo T61 auto) taken down to a bodyrepair shop for some work done and now it wont start while its down there. They have a good spark, and we have fuel at the fuel rail with loads of pressure! we also have a pulse. So basically we have all the components to start the car but it just wont. all plugs be cleaned checked and all spark well. They charged the battery for a good week or 2, tried a different battery and also tried bypass immobliser thinking it mite be that but still would not start. The body repair garage have been very helpful and have had an auto electrican in and checked all connectors and plugs and all is fine. So things that have been tested: 1- battery charged and tried different one 2-fuel at fuel rails - loads pressure 3- we have a pulse 4-cleaned checked spark plugs 5- tried bypass immobliser to no avail From what i could hear on the phone when they tried to start it, it cranked over (didnt click) but jus isnt firing, so one of the mechanics down there seems to think its could be somthing to do with the timing is out and therefore wont fire correctly. Any opinions or suggestions are most welcome and would be grately appreciated as the work on the car has been done for nearly a week now and im just dieing to get her back Cheers Bazsupra Quote Link to comment Share on other sites More sharing options...
tooquicktostop Posted December 4, 2009 Share Posted December 4, 2009 I trust it is running an aftermarket ECU ? what is that saying on startup attempt? Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 4, 2009 Share Posted December 4, 2009 No its running standard ECU when the single was installed and has Super-AFC to control the fueling, sorry if i come up with newb answers quite new to this so bare with me guys cheers Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 4, 2009 Share Posted December 4, 2009 hi guys just to let you know we hav eliminated to crankshaft sensor as the rpm needle moves on 0 whilst cranking so that was a disapointing sorry 4 bad spellin on mobile Quote Link to comment Share on other sites More sharing options...
add heywood Posted December 4, 2009 Share Posted December 4, 2009 I had the same sort of problem, turned out to be a broken wire on the water temp sender. The ecu didn't realise the engine was cold and didn't give it enough to start.... Have you checked for error codes if your running a standard ecu?

jon5698 Posted December 4, 2009 Share Posted December 4, 2009 Have them check to make sure they haven't pulled an earth wire off the engine from somewhere. Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 5, 2009 Share Posted December 5, 2009 ok i will get them to have a look at that on monday, I got a phone call from the repair garage and they had noticed that my clifford alarm had bee badly corroded and some wires have very poor conections due to the corrosion. I am awaiting pictures so i can show you guys but could this be the causing it not to start? many thanks for your opinions n advise much appreciated Quote Link to comment Share on other sites More sharing options...
Abz Posted December 5, 2009 Share Posted December 5, 2009 I had a similar problem, I brought my old FTO in this condition. Brought it home, left battery disconnected for 48 hours while I got her charged up. This reset the ECU & then just plugged her back in & started fine! Though the issue restarted again randomly & it turned out it was a link from a matrix replacement which caused a link on gearbox ECU. I'd try the disconnecting of battery route first. Then my money would be on one of the ECU's. Quote Link to comment Share on other sites More sharing options...
dude Posted December 5, 2009 Share Posted December 5, 2009 ok i will get them to have a look at that on monday, I got a phone call from the repair garage and they had noticed that my clifford alarm had bee badly corroded and some wires have very poor conections due to the corrosion. I am awaiting pictures so i can show you guys but could this be the causing it not to start? many thanks for your opinions n advise much appreciated Not really because the alarm will immobilise by cutting either spark or fuel, both of which you seem to have.

absz Posted December 5, 2009 Share Posted December 5, 2009 if you have fuel and spark then it can be : timing- low compression- blocked exhaust-bad fuel-blocked intake. check all these and it SHOULD start. Quote Link to comment Share on other sites More sharing options...
Ian C Posted December 6, 2009 Share Posted December 6, 2009 Too much fuel can cause failure to start as well. Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 6, 2009 Share Posted December 6, 2009 Cheers for all your suggestions and opinions, Greatly appreciated i will get them to start checking these on monday. Only annoying thing is the body repair garage dont know how to check for fault codes on the supra so i have asked Ryan G to pop down there will his knowledge of supra to see if he can shed some light, but he cant get there till the 14th so i guess ill just get the garage to check over things you guys have said and we can go from there!

Guest Bazsupra Posted December 10, 2009 Share Posted December 10, 2009 OK guys little update, the corroded circuit board is for the alarm but is only for the different alarm tones so wont actually affect the alarm itself. The repair garage had an auto electrican round again to have a look, and he seems to think it could be something to do with the fuel, is there a cut off switch? and if so where is it located? although at most i think its only 2.5 months old, i will ask if they can refill it and try again. Also just to let you guys know that the alarm hasnt been bypassed, they tried to do it, but are fhaving difficulty finding the loom and alarm wiring, as this was done by previous owner "friend of a friend" cheers Quote Link to comment Share on other sites More sharing options...
AlanM Posted December 10, 2009 Share Posted December 10, 2009 Try changing the fuel, worked for me with same symptoms Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 10, 2009 Share Posted December 10, 2009 Ok guys got more news! - although this is starting to become very annoying Changed the fuel and still turns over but just wont start. We have now bypassed the alarm and still wont start. Now this leads me to the timing could be out? now this is where i get lost and have very basic knowledge about. Where can i go to get the timing sorted?? Is this a costly procedure?!? Does anyone know of a mobile autotechnician that could get to the car to sort?!? Many thanks for all your suggestions so far, its been trial and error but we are slowly eliminating the causes. Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 10, 2009 Share Posted December 10, 2009 seems quite random that it could be timing issue, as the car drove fine and never skipped a beat when i drove it to the repair garage, how can timing be out without physically touching the engine.. seems very strange to me Quote Link to comment Share on other sites More sharing options...
dr_jekyll Posted December 10, 2009 Share Posted December 10, 2009 if it drove in and knowbodys touched the vtimeing then it cant be that. check the fuel relay. had similar prob on an mx 5 ant the relay was geting an intermitent connection so we were seeing a live but it was not enoght to run the pump propperly, put 12v staight down the line with a probe and see if it will fire.

Chewie Posted December 10, 2009 Share Posted December 10, 2009 A few questions before you go tearing the electrics out. Was it working before you took it to the repair shop? Why would all of a sudden the timing be out. When I was a student, for a giggle we used to swap the ignition leads 180 deg so that the spark would be on the exhaust stroke. Then watch the victim flat the battery out trying to start it. What was the work being done on it? 2 weeks is quite a long time to charge a battery.

Guest Bazsupra Posted December 10, 2009 Share Posted December 10, 2009 Thanks for your quick responses, Dr_jekll i will ask if they can have a go that and see what they get. With regards to the diagnostics test, this cannot be done as they dont know how to do it and i cant get to the car, so i have asked Ryan G to pop in for an hour on monday and have a look as he might be able to shed some light on this and he will do a diagnostic test for me. The work being carried out is cosmetic , just had the roof lining replaced and resprayed as the bonnet came up. i will see if i can get a audio or video clip of the sound it makes when it tries to start maybe this might help? cheers for your helps guys Quote Link to comment Share on other sites More sharing options...
Guest Bazsupra Posted December 10, 2009 Share Posted December 10, 2009 The fuel pump is working fine, has pressure and has fuel there so its no that, the technician there seems to think that its just not gettin a signal from somwhere either the cranks ( although the need does move whilst cranking), or the mixture is not quite right? what other sensors will inhibit a car from starting if faulty?

Guest Bazsupra Posted December 14, 2009 Share Posted December 14, 2009 (edited) Well guys some good news at last! Ryan went down to GVN coachworks where the car had its work done and as random as it may sound the timing was out! Cambelt had slipped 7 teeth and Ryan also found that my belt tensioner was quite rusty and this was the probable cause for the belt to slip. Also changed the plugs to some copper ones as they previous (iridiums) had burnt out, Ryan will go into more detail when he posts but finally some good news! Will be picking her up soon as i got email from GVN saying is up and running, i will treat this as my early Xmas present Cheers for all your advise guys much appreciated!! Also just want to say big thank you to Ryan! nice 1 m8 Edited December 14, 2009 by Bazsupra (see edit history) Quote Link to comment Share on other sites More sharing options...
