keef701 Posted February 16, 2011 Share Posted February 16, 2011 Lads, I have got a problem with my Jspec TT 6 Speed, that is puzzling me. On my way home from work tonight, I had to stop and get petrol, the gauge was just above empty. So having put in about £60 of the Tesco momentum99( I have used this for a while with no problem) the car starts up as normal, I drive off and after about a 1/4 of a mile, I put my foot down out of a roundabout, and nothing, the engine loses all power. I manage to pull over and at this stage the engine is just about idling, but any throttle and it tries to die. Slowly I build up the revs to try to get it moving again, but as soon as the clutch is let out it dies. I park it up, and after a while I managed to get it towed to my mothers house who fortunately lived only about a mile a way. Now, having done a search on the forum for possible causes, I have checked the fault codes (jumped TE1 and E1) and nothing is stored. I reset and started up the engine again, and recheck for the codes, but again, nothing is stored. I have jumped B+ and FP to check the fuel pump, and I can hear it running o.k, but there is not the obvious fuel rushing sound that can be heard when this is done. I have checked all obvious hoses, small bore and intercooler hoses, and nothing appears obviously wrong. I have checked all the coil pack connectors and clips, and again, nothing appears wrong. I am now starting to think either the petrol is bad(water contamination?) or when it was low on fuel I have disturbed dirt or something in the system, and it has blocked something. The fuel filter is only about 300 miles old, so could it have blocked up that quickly? The engine will still start, and idles at about 650rpm, but as soon as you touch the throttle, there is no power. Has anybody got any other ideas of things that I can check? I will probably jack the car up tomorrow and have a look at the filter, and drain some fuel to see if its any good. Up till now the car has never missed a beat, so this has really taken me by surprise! Quote Link to comment Share on other sites More sharing options...
dude Posted February 16, 2011 Share Posted February 16, 2011 Do you have a fuel pressure guage, had this before and it was fuel delivery related. Quote Link to comment Share on other sites More sharing options...
Bailey. Posted February 16, 2011 Share Posted February 16, 2011 where did you buy it from? water in the fuel???? Quote Link to comment Share on other sites More sharing options...

ronttuk Posted February 16, 2011 Share Posted February 16, 2011 i had the same problem today but i put petrol in a diesel !!! Quote Link to comment Share on other sites More sharing options...
Bailey. Posted February 16, 2011 Share Posted February 16, 2011 The only reson i say that is i had a mate who had a 350z, he filled up at sainsburys and was missing straight away, got about 2 miles down the road and it cut out in traffic and wouldnt re start, sure enough on the side of the road we drained the tank and it was flooding with clumps of water. 40 liters was basically a 50/50 split. Just an idea mate. Quote Link to comment Share on other sites More sharing options...
keef701 Posted February 16, 2011 Author Share Posted February 16, 2011 where did you buy it from? water in the fuel???? Bought it from the local Tesco petrol station, never had a problem before from them. I might be able to drain some and check for moisture.

Kopite Posted February 16, 2011 Share Posted February 16, 2011 Might be worth ringing them and loggin the comment in case you need to come back for some actual petrol without water in it Quote Link to comment Share on other sites More sharing options...

keef701 Posted February 16, 2011 Author Share Posted February 16, 2011 Do you have a fuel pressure guage, had this before and it was fuel delivery related. No, I haven't got a fuel pressure gauge. I there any other way that I can check for the correct fuel delivery rate. Can the stock FPR play up sometimes? Quote Link to comment Share on other sites More sharing options...
fastcar Posted February 16, 2011 Share Posted February 16, 2011 (edited) my uncle had this a few weeks ago. filled up at tesco with petrol drove down the road and started having problem and gave the description u have given. turned out to be bad fuel. not saying this is your problem but does sound the same. TBH i would never use supermarket fuel i have heard to many bad stories about them.

keef701 Posted February 16, 2011 Author Share Posted February 16, 2011 I am running a single Walbro pump. The car was running perfect until I refilled. Quote Link to comment Share on other sites More sharing options...
keef701 Posted February 17, 2011 Author Share Posted February 17, 2011 I had another look at the car today. Got it up on some ramps, and removed the fuel filter. I made up a hose that fitted over the hardline that comes from the pump, and then bridged +B and FP again, powered up and caught the fuel in a clear jug. The one litre jug filled within about 30 seconds, so the pump is flowing quite well. I powered down the pump and had a look at the fuel I collected. There is no water visible and the fuel looked clean. I had a look at the filter, and blew through it. No problems with that, so refitted the filter and the fuel lines and restarted. Problem still there. Slightly lumpy idle, and tries to die as soon as the throttle is touched. I then had a brainwave, and thought it may be either my RLTC or Emanage, interferring with the injectors, so as both are wired into a fields harness, I quickly disconnected the harness and plugged the standard harness direct into the ECU. Started up, and problem still there. I just sounds and feels as if the engine is running out of fuel. I am now starting to run out of ideas. Would a faulty fuel dampener or the pressure regulator, cause this fault or is there anything else I am missing? O2 sensor fault maybe? Any ideas lads??

dude Posted February 17, 2011 Share Posted February 17, 2011 Map sensor working ok and check the little vacuum canister in the plenum to the left of the IACV as you look down on it, take it out and make sure you can blow thru it. Quote Link to comment Share on other sites More sharing options...

O.K thanks for the advice, I will have a look at it again tomorrow. I have a spare MAP sensor I can try. Fingers crossed!! Quote Link to comment Share on other sites More sharing options...
wallis Posted February 17, 2011 Share Posted February 17, 2011 ive had this before, it turned out to be a loose broken coil pack clip. Quote Link to comment Share on other sites More sharing options...
SupraDan24 Posted February 17, 2011 Share Posted February 17, 2011 Think it was a 1 or 2 years ago where my local Tesco's ruined about a hundred drivers day's by mixing there fuels up, diesel in unleaded etc. It isnt the first time its happened either. They had to pay alot of compo out as well if i remember. Quote Link to comment Share on other sites More sharing options...

keef701 Posted February 18, 2011 Author Share Posted February 18, 2011 O.K, a bit of an update, following dudes advice, this afternoon I checked the canister pot on the side of the manifold, and that was clear. I swapped over to another MAP sensor, and started her up. No improvement. So I decided to disconnect the battery for ten minutes, to reset the ECU, and have a cuppa at the same time! Reconnected and started her up. Again no improvement. Whilst stood there scratching my head, I decide to bridge +B and FP again. A strange thing happened, the idle got smoother! and the revs would pick up stronger when the throttle was blipped. So now thinking that supplying the full 12v to the pump, improved the fuel flow and I could hear more fuel returning to the tank, there must be a problem with either the FPR or the pump. As I have only got a standard FPR and no pressure gauge, the next easiest check would be to have a look at the fuel pump to see if the filter was blocked or missing. 20 minutes later, I have got all the fittings off the top of the pump, and start to lift the pump hanger from the tank. As soon as I had lifted it, the possible cause of the problem was staring me in the face. The rubber fuel hose that goes between the top of the pump and the hardline in the hanger, had magically turned into something that ressembled black chewing gum!!! The braiding had blow out and the inner core had now split open. It was a miracle that it was getting any fuel at all. So I am a bit happier now, will get some fuel hose tomorrow, and start putting back together all the bits I have pulled out of the car in the last two days! I am 99% sure this is the problem (I am saving the other 1% for sods law), so thanks for everyones input and suggestions, and maybe this might help someone in the future with a similar problem. Thankyou. Quote Link to comment Share on other sites More sharing options...
BazzaAlpine Posted February 18, 2011 Share Posted February 18, 2011 If I recall correctly what happened was the tanker that carried the fuel had carried some silicon substance at some point so the fuel got contaminated. The silicon then coated the O2 sensors I beleive? and so they had to pay out to have all them replaced. Quote Link to comment Share on other sites More sharing options...

Thankyou. That is very similar to the problem I had which is why i asked if you had 2 pumps, in my prob one of the pipes to 1 pump had come adrift.

keef701 Posted February 20, 2011 Author Share Posted February 20, 2011 Right, here is my final update on this. Got a couple of inches of fuel hose yesterday from my local motor factors, for free, fitted it to the pump and refitted the whole assembly back into the car. Refitted all the other bits I stripped off over the last few days. Reprimed the system and she started up straight away. Idle was smooth, and the power is back. Thank God!! Total cost to find fault and repair, £1.34, which was the litre of petrol I pumped into a jug. So if anyone in the future has a similar problem, and had already explored other causes, this might just help them! Thanks. Quote Link to comment Share on other sites More sharing options...
dude Posted February 20, 2011 Share Posted February 20, 2011 Ordinary fuel hose is not designed to be left immersed in petrol you need a certain type, I believe CW sells it. Quote Link to comment Share on other sites More sharing options...
