ultimatepug 0 Posted March 7, 2008 right... its been rebuilt by somebody whom i know, and thoght could do a good job... hmmm.. lemme explain.... engine all back in and together, fitted it, turns over but wont fire.... took the rovcker cover off to find no oil getting to the top. turns out the head gasket was the wrong way round....... thats all sorted now... anyways,,,, the following has been checked to eliminate... good spark there plenty of fuel reaching the rail good compression ecu tested on another 205 mi16, fine timing is bang on anybody got any ideas? crank sensor is to be replaced in case its that will be testing it with omex ecu/loom to eliminate a prob with the loom if you have any ideas, please fire away! lol adam Share this post Link to post Share on other sites
DrSarty 90 1 Cars Posted March 7, 2008 You've said fuel at the rail, but are the injectors firing? Share this post Link to post Share on other sites
ultimatepug 0 Posted March 7, 2008 You've said fuel at the rail, but are the injectors firing? yep, tried them on another engine too.. Share this post Link to post Share on other sites
jackherer 543 Posted March 7, 2008 If its injecting fuel and sparking check that the ECU coolant temp sensor is working and connected. Share this post Link to post Share on other sites
ultimatepug 0 Posted March 7, 2008 lead orders ok, will check coolent temp sensor,, Share this post Link to post Share on other sites
DrSarty 90 1 Cars Posted March 7, 2008 (edited) Please forgive me stating possibly the obvious, but remember lead order from a Pug (arse about face - 1 at the clutch end) point of view, as it sounds like it's something basic to me. Enough fuel & air with good spark at right time = engine run. Is it even catching or just spinning?

ultimatepug 0 Posted March 7, 2008 just spinning... Share this post Link to post Share on other sites
DrSarty 90 1 Cars Posted March 7, 2008 (edited) And my bone firing order secondary suggestion? Coz we've all done it! EDIT: Sorry I'll wang it here as well.

peter 20 Posted March 7, 2008 Any luck with this? Mine is doing exactly the same.... Share this post Link to post Share on other sites
DamirGTI 342 Posted March 7, 2008 (edited) Too weak (cold) spark + too rich/lean fuel mixture perhaps so that it can't ignite the mixture i've had something similar on my high CR engine -> was cranking for ages every morning to start it up and finally fixed this by changing the ignition amp. (for another one which saturate the coil better then the other me thinks ) and adjusting the fuel mixture ... however it still starts just a little bit harder in cold morning (needs a few attempts - 2 or 3 times cranking until it fires up ..) but this is modified engine so it's not unusual that it's a little bit rough at startup .. Regards ! Damir EDIT : tried with the easy start spray ? Edited March 7, 2008 by DamirGTI Share this post Link to post Share on other sites
cybernck 402 1 Cars Posted March 7, 2008 i've got the same problem with the front engine in my 205 Mi32, since it's not being driven regularly. but the strange thing is - it fires up easily when bump-started (using the rear engine) . Share this post Link to post Share on other sites
DamirGTI 342 Posted March 7, 2008 Which brand of ignition amp and coil do you have ? I've found (by testing various types..) that theres some differences in startup with particular brand of ignition amp. and coil combination , also some difference in throttle response/mid range acceleration (well at least on my engine ) Rgs !

cybernck 402 1 Cars Posted March 7, 2008 who, me? just a standard Bosch MTR01 ignition amp and standard coil . Splitfire spark plugs though and sometimes it helps when i swap them for normal ones, sometimes it makes it worse . Share this post Link to post Share on other sites
DamirGTI 342 Posted March 7, 2008 who, me? just a standard Bosch MTR01 ignition amp and standard coil . Splitfire spark plugs though and sometimes it helps when i swap them for normal ones, sometimes it makes it worse . Well as far as i'm aware the Bosch combo is good one , i've had problems with the "Magneti Marelli" amp. and Bosch coil combination - when the car was left standing one day or more it was a real nightmare to start him up afterwards .. but once it was started (after a loooong cranking) was driving fine , also the strange thing was that the engine was performing much faster with this "MM" amp. - strong punchy acceleration , sharp throttle response like it had a few Hp more - with Bosch amp/coil it feels a little bit "flat" not so lively like with the MM amp. but as i sad the startup after a long standing was a nightmare so i've swap the Bosch amp. back ... As for the Splitfire plugs - don't get me wrong but i've found them a real crap no worth the money , to me the NGK ones are the best and cheap try one step colder/hotter plug and see if that helps ... (also you can make/modify the ordinary plugs to fire like those Splitfire ones try it out with some spare set of plugs : http://www.guy-croft.com/phpBB3/viewtopic....ark+plug#p4704) Damir Share this post Link to post Share on other sites
cybernck 402 1 Cars Posted March 8, 2008 hmm, now you mentioned it, i'm not sure which one is on the car, but i've got both Bosch and MM in the spares . Share this post Link to post Share on other sites
