Homer Posted February 6, 2007 Share Posted February 6, 2007 I've left it stood for a few days, went to start it last night but it wasn't good. It fired up and ran very rough for about 30 seconds, it wasn't firing all cylinders and stank of petrol. I stopped it, tried to restart and it won’t fire up at all (just cranking then a few cough's from the exhaust). I've checked the following: - Fuel pressure (okay at 36psi) - Re-loaded emanage map (no difference) - Removed emanage (no difference) - Checked plugs (Soaked in fuel, as are the tops of the cylinders) - No fault codes recorded (ECU reset and rechecked) And its still not firing up Any ideas what else to check? PS: all this happens 5 days before it's due to get mapped, got the RR booked and everything on Saturday Quote Link to comment Share on other sites More sharing options...
JustGav Posted February 6, 2007 Share Posted February 6, 2007 You might have to dry the plugs out a bit.. You are running an ultimate are you not? There is a way to use the plug fouling feature. I believe and need to be corrected on this. Go full WOT and click to ignition.. Let me just quickly double check. Quote Link to comment Share on other sites More sharing options...
uk-rich Posted February 6, 2007 Share Posted February 6, 2007 i would take the plugs out, and leave them out for a while (ideally airline the boresto dry the excess fuel out) Quote Link to comment Share on other sites More sharing options...

Last fillup was of Ultimate in Hayling Island I don't think the EMB has any anti-fouling feature (unless I've mistaken?) i would take the plugs out, and leave them out for a while (ideally airline the boresto dry the excess fuel out) I'll take them all out now... got nothing to lose! I removed the front 2 and dried them off earlier, but when cranking again it barely made any difference Quote Link to comment Share on other sites More sharing options...

As said above, take the plugs out, airline the bores to get rid of the excess fuel. Quote Link to comment Share on other sites More sharing options...
Alex Posted February 6, 2007 Share Posted February 6, 2007 The EMB doesn't have the anti fouling no. Do the plugs, but if that doesn't help I'd look to your harness...I once managed to lock the injectors open with a bad earth and that killed it....whilst at LeMans miles from home!

I removed the harness completely and just used the stock ECU and it ran exactly the same. Previously it at least idled with just the stock ECU. Will check the earths on around the ECU now...

kosmic Posted February 6, 2007 Share Posted February 6, 2007 As Alex said seems like either a bad earth wiring fault or something causing your injectors to stay open. Quote Link to comment Share on other sites More sharing options...

Homer Posted February 6, 2007 Author Share Posted February 6, 2007 I beleive there's only one earth on the ECU harness? It was previously hacked into where the FCD used to be, I've just cut and resoldered it but that didn't help. The ECU is also properly bolted down (Not sure if its earthed from the casing, but best to check..) The plugs are out now to let it all dry out. The tops of the cylinders are soaked in fuel so will leave it until late this afternoon before refitting, though I don't think plugs are the issue.

rob wild Posted February 6, 2007 Share Posted February 6, 2007 also check your temp sensor and wiring as that was having an effect with my car not start from cold. Quote Link to comment Share on other sites More sharing options...
Homer Posted February 6, 2007 Author Share Posted February 6, 2007 I'll clean the O2 sensor shortly. Rob, do you mean the water temp sensor or another? PS Alex, if you see Ian can you ask him to check his PM's, thanks. Quote Link to comment Share on other sites More sharing options...
Ian C Posted February 6, 2007 Share Posted February 6, 2007 What did Phoenix do to fix it last time? Quote Link to comment Share on other sites More sharing options...
Homer Posted February 6, 2007 Author Share Posted February 6, 2007 What did Phoenix do to fix it last time? It went to them with a misfire (not the same as the current issue), they installed the injectors and emanage and replaced the faulty injector insulators (one of which I had crimped). TBH it sounds and ran exactly the same as when I wired the MAP sensor up the first time round (except this time it does it with the fields harness removed!) EDIT: also in answer to your PM: There is voltage showing on the MAP sensor reading and it does vary very slightly. It is overfueling, I took a couple of plugs out, dried them off and cleaned off the carbon. Reinstalled, cranked it a bit and they came out soaked in fuel again.

rob wild Posted February 6, 2007 Share Posted February 6, 2007 I'll clean the O2 sensor shortly. Rob, do you mean the water temp sensor or another? Yeah water temp sensor just above the alternator, turn out one of the many problems with mine was a fault temp sensor which was making the car overfuel.

Homer Posted February 6, 2007 Author Share Posted February 6, 2007 Yeah water temp sensor just above the alternator, turn out one of the many problems with mine was a fault temp sensor which was making the car overfuel. There's two sensors in the pipe, do you remember which one it is? Once of them has a large flange, the other much smaller. IIRC the smaller one often cracks on removal, though I do have a spare of the larger one... Quote Link to comment Share on other sites More sharing options...
supra matt Posted February 6, 2007 Share Posted February 6, 2007 its the large one mate the small one is for the gauge in the dash Quote Link to comment Share on other sites More sharing options...
Homer Posted February 6, 2007 Author Share Posted February 6, 2007 Just reinstalled the plugs after letting them and the cyclinder dry out. It fired up, but was the same as yesterdy - serioulsy over fueling and barely firing. Unplugged the temp sensor but that didn't make any difference, I'm not convinced a faulty temp sensor could make it overfuel by this amount. It's almost like the injectors are just pouring fuel out of them. Quote Link to comment Share on other sites More sharing options...
terribleturner Posted February 6, 2007 Share Posted February 6, 2007 Could it be one of the injectors has got stuck open?? Am sure there was a car up turbofit that had the same problem. Quote Link to comment Share on other sites More sharing options...

It can't be all of them though, every cylinder is flooding with fuel. Unless its a wiring issue... Quote Link to comment Share on other sites More sharing options...

Guest Bijal Posted February 6, 2007 Share Posted February 6, 2007 it may well be the plugs in this situation? can you not buy and fit a cheap set of for like 6 quid and try them? its just to get the car unning and to 100% aliminate the plugs. the amount of fueling on the plugs your describing seems to have damaged the plugs, even if you clean them. the cause maybe the extra fueling during cold start (which is normal) and maybe has fueled the engine a little too much during our short spell of cold evenings and mornings in the past few days? try the plugs. bijal Quote Link to comment Share on other sites More sharing options...
Marty Posted February 6, 2007 Share Posted February 6, 2007 These plugs will do you if you want to try new plugs as bijal says (up to 1.3bar) Nice and cheap too, £12 all in Link to ebay Quote Link to comment Share on other sites More sharing options...

It fired up, but was the same as yesterdy - serioulsy over fueling and barely firing. this may seem to you that its "over fueling" but in fact it "could be" the plugs not firing to their full potential due to the damaged caused from over fueling, hence not burning the fuel in the cylinders and looking like its over fueling. bijal Quote Link to comment Share on other sites More sharing options...
