hodge Posted October 28, 2006 Author Share Posted October 28, 2006 Theres a system check feature on the E01 called system check and I got the readings from that. Do you think I should put a multi meter on the MAP wire on the ECU and try and start it. This is crazy this its really annoying me now. Ive got a nice shinney decat in the house to put on but i cant cos I cant get it to the garage to put it on the ramp. This needs sorting ASAP> Ive got a MAP sensor that Colsoop has sent me I should receive it on Monday hopfully. But if I can sort it out by them, that would be a bonus.

Matt Harwood Posted October 28, 2006 Share Posted October 28, 2006 Yes. The only way to se if the ECU is getting the correct signal, is to put a meter on the wire just before it goes into the ECU. The E01 may 'think' it's giving the correct signal, but until you check it externally, you can't be certain. If it is reading ~2.6v and drops as you crank, that's showing the MAP sensor is working properly. I'd suggest removing the spark plugs and giving them a good clean up, and re-setting the ECU. Then check for new fault codes as you try to start the car. Link to comment Share on other sites More sharing options...
hodge Posted October 29, 2006 Author Share Posted October 29, 2006 ok them, thats the jobs for today if it doesnt work then back to the drawing board. ingers crossed. Link to comment Share on other sites More sharing options...
hodge Posted October 29, 2006 Author Share Posted October 29, 2006 Update. Ive tried the test on the ECU and its putting out 2.6v ish but when I crank the car it doesnt go down infact it doesnt move at all. Im going to do the plugs and reset the ECU now.

hodge Posted October 29, 2006 Author Share Posted October 29, 2006 updateTook plugs out and cleaned them, they were totally black and I could smell the petrol inside the plug holes. While I was on I took my O2 sensor in some lemon juice and cleaned that, thought it couldnt do any harm.. Put everything back together and reset the ECU and did a fault check, only fault which shows is code 31 and the O/D light is flashing. When I tried to start it the car stank of petrol. Could this be the map sensor or could it be anything else. Link to comment Share on other sites More sharing options...
Matt Harwood Posted October 29, 2006 Share Posted October 29, 2006 That's rather strange. The MAP sensor seems to be giving you the correct voltage, so it seems to be working. I'm presuming you have got a J-spec, pre-vvti, TT ? Link to comment Share on other sites More sharing options...
hodge Posted October 29, 2006 Author Share Posted October 29, 2006 yeah thats right mate. You said that the voltage should drop when I turn it over but it just stayed the same and there was a really strong smell of petrol when I tried to start it.

Matt Harwood Posted October 29, 2006 Share Posted October 29, 2006 yeah thats right mate. You said that the voltage should drop when I turn it over but it just stayed the same and there was a really strong smell of petrol when I tried to start it. Well, the voltage will drop as a vacuum is created, but bearing in mind the starter motor only turns the engine over at about 150-200rpm, it won't be creating much vacuum, so the voltage won't be dropping much. As the engine fires, it should drop. To be honest, I'm a little stumped by that. I suppose it's worth changing over the MAP sensor, just to see if that works, but I would be suprised as the voltage output is correct Have you unplugged the ECU recently? - Could the pins be bent/damaged? Had any work been done to the car prior to it not starting? Link to comment Share on other sites More sharing options...
hodge Posted October 29, 2006 Author Share Posted October 29, 2006 No mate There was no problems at all with the car until I put that shitty bp ultimate petrol in them it all went down hill from there. Could a change in petrol effect anything so seriously. Link to comment Share on other sites More sharing options...
hodge Posted October 29, 2006 Author Share Posted October 29, 2006 Ive just noticed that when I take the handbrake off the triangular warning light stays on. I dont know if that makes any difference at all to your thinking. Link to comment Share on other sites More sharing options...
Matt Harwood Posted October 29, 2006 Share Posted October 29, 2006 Can't see that changing petrol would make a difference. I've used some crappy 95 octane stuff when I've been caught short before, so I really doubt that Ultimate would cause any problems at all. The triangle is part of the warning system. Just telling you somethings not right for the car to be driven, (could be as simple as door open, or as serious as a multitude of fault codes). Well, my next step would be bypass the Greddy, just to be safe, and change the MAP sensor. Reset the ECU again, and try again... Out of interest, where are you?

hodge Posted October 30, 2006 Author Share Posted October 30, 2006 Im near newcastle in the North east of England. What do you mean by bypass the Greedy. Do you mean the whole boost controller or just the FCD. Link to comment Share on other sites More sharing options...
Matt Harwood Posted October 30, 2006 Share Posted October 30, 2006 A tad far for me to come and have a look! Bypass the FCD part. Put it as close to stock as possible. Link to comment Share on other sites More sharing options...

hodge Posted October 30, 2006 Author Share Posted October 30, 2006 Ive tried bypassing the FCD and it makes no difference an all. When I took the plugs out the last 3 plugs had oil on them, I dont konw if that tells you anything, the further towards the back of the engine the worse they got. the back 1 nearest the bulkhead had quite abit. Will this be just the valve stem seals, and am I just clutching at straws here. Link to comment Share on other sites More sharing options...
hodge Posted October 30, 2006 Author Share Posted October 30, 2006 OK Changed the MAP sensor, done an ECU reset, still no joy at all. What else can I do. Im sick as F*$k now. Someone else has bound to have had this problem. Im almost 100% certain its overfueling on startup so it wont fire. When its warm it runs perfect no problems, just when its been standing it takes ages to hold revs to start but now it wont fire at all. Come on guys im desperate here.

s crane Posted October 30, 2006 Share Posted October 30, 2006 I can remember some one saying about a spit fuel pipe in the petrol tank giving poor fuel pressure,going by the way your problems started with having to rev up to clear in mornings.best of luck steve Link to comment Share on other sites More sharing options...
hodge Posted November 2, 2006 Author Share Posted November 2, 2006 Well ive just gave up now. Ive no idea whats wrong with the car so I shipped it off to Envy today, to let those boys sort it out. So hopfully ill have it back next week. Fingers crossed the bill aint gona be too big though. Ha Ha Ha. Link to comment Share on other sites More sharing options...
hodge Posted December 20, 2006 Author Share Posted December 20, 2006 UPDATE Thought id keep you all in the picture, god forbid this happens to any of you. The car has been at Envy for 5/6 weeks and I think theyve checked every electrical componant in the bloody thing and doesnt seem to be any of them. They have discovered that when you turn the car over to try and start it then take the plugs out, if you rock the car you can see the petrol sloshing around in the plug holes, (not good). So its overfueling, not underfueling. fuel pump and petrol has now been changed and all lines cleaned out. When they took the intake off they found a swimmingpool of petrol inside the bottom of the intake. So finger seems to be pointing to the injectors are sticking open when firing. nerxt job is to test the injectors and rebuild the intake and hopefully this will cure the problem. I need to phone him next Thurs now so hopefully ill have some good news. But up til them im gona have to drive me misus's Audi TT. Its not a bad car but it aint a SUPRA thats for sure.
