PC Pete Posted April 14, 2013 Share Posted April 14, 2013 Finally got my R400 kit finished so start up day was planned for today - many attempts but no success in getting the engine to fire... Situation - 20 liters of fuel in the tank good oil pressure on cranking engine turns over no problem. fuel pump can be heard working. all electrics work ok. Took off fuel line connection at the injector rail and got a fine mist of fuel so pressure in the pipe. (did this without turning over the engine - just residual pressure from the previous attempts.) Crank sensor connected. Fuel cut off switch working - tried a spare also. Got the very occasional small splutter but nothing serious. Tried squirting neat fuel (very small amount) into the air intake - got a small puff of smoke from the exhaust. Tried all this over the space of a couple of hours, allowing time for the starter to cool and to recharge battery. Checked all electrical connections with engine wiring loom to chassis loom ( the big fat plug) - looks ok. Likewise the plug to the ECU. So - any ideas? Have you experienced this situation before? Likely culprits? Injectors not being "switched on" as it were? No spark? (have had two of the plugs out and they look ok - no evidence of them having lit any fuel.) Bad ECU? My third build in 6 years - and this has been the worst - I should not have been surprised about today! Many thanks in advance..

tbird Posted April 14, 2013 Share Posted April 14, 2013 guess the first thing two things to check, are do you see a decent spark and how is your compression. sorry just read 3rd build in 6 years, those suggestions too obvious how bout plugs sparking in wrong order, leads not correct Tim Edited by - tbird on 14 Apr 2013 21:49:43 Link to comment Share on other sites More sharing options...
PC Pete Posted April 14, 2013 Author Share Posted April 14, 2013 Hi Tim thanks for your time. Haven't yet "seen' a spark - had to stop work on it a while ago. Will have a look see later in the week. I hope the compression is good - it's a brand new engine! thanks again Peter Link to comment Share on other sites More sharing options...
tbird Posted April 14, 2013 Share Posted April 14, 2013 re compression was thinking more around valve adjustment rather than rings, in fact could timing be out Tim Link to comment Share on other sites More sharing options...
PC Pete Posted April 15, 2013 Author Share Posted April 15, 2013 Thanks again Tim. I'll have a think around that - not sure how to check it mind you. It will have to wait now - work calls! Many thanks again Peter Link to comment Share on other sites More sharing options...
