tooquicktostop Posted April 3, 2009 Share Posted April 3, 2009 Really mate, stop playing with it, you dont know what you are doing, get a trailor ordered and get it to a tuner to sort it out, it might be as simple as an O2 sensor and a remap and away you go Quote Link to comment Share on other sites More sharing options...

wilkorangerover Posted April 3, 2009 Author Share Posted April 3, 2009 member jimmy_supra has lend me his old oem one not hundred per cent if its any good not sure if they can stop fuel going to the plugs? Quote Link to comment Share on other sites More sharing options...
Scott Posted April 3, 2009 Share Posted April 3, 2009 not sure if this is any good to you but take out the spark plugs then turn the fooker over. If you don't take out the efi fuse then the pump will fire fuel into the cylinders. This will flood it but you will know whether its fueling or not.

Homer Posted April 3, 2009 Share Posted April 3, 2009 I don't mean to sound rude or disrespectful, but please, for your own sake, stop messing with it. The car needs to go to a competent garage and needs to have the map and everything else checked. As mentioned, your most cost effective option is to get Ryan.G to visit your place, fit a solaris and see what the car is doing. If you continue to mess around with it, it will likely cost you a lot of money to put right Quote Link to comment Share on other sites More sharing options...

SimonB Posted April 4, 2009 Share Posted April 4, 2009 It won't be the O2 sensor, assuming you're talking about starting it from cold. It will be in open loop until the sensor warms up, so won't be using the O2 sensor. It will be a dodgy map or incorrect fuel pressure for the map if you have an adjustable FPR, but most likely the map. Don't run it if it's running very rich, it will destroy your engine through bore wash - i.e. the excess fuel will wash the oil from the cylinder walls and you will score the cylinder walls and knacker the rings.

mikeyb10supra Posted April 4, 2009 Share Posted April 4, 2009 Dont rule out something simple like the fuel pump ECU.....especially if you have tinkered with the fuel system of late. a bad earth or faulty connection would cause rough running and give you symptoms like you are currently having Quote Link to comment Share on other sites More sharing options...

wilkorangerover Posted April 4, 2009 Author Share Posted April 4, 2009 there is only power to the fuel pump in the `start` position , is this correct??? no power to the pump with ignition on, just start position.... Quote Link to comment Share on other sites More sharing options...
Scott Posted April 4, 2009 Share Posted April 4, 2009 there is only power to the fuel pump in the `start` position , is this correct??? no power to the pump with ignition on, just start position.... Ignition on should prime fuel system via the pump. You should hear a drone. Quote Link to comment Share on other sites More sharing options...
wilkorangerover Posted April 4, 2009 Author Share Posted April 4, 2009 no it does nothing until engine starting no power going to the pump until engine turning over Quote Link to comment Share on other sites More sharing options...
Scott Posted April 4, 2009 Share Posted April 4, 2009 no it does nothing until engine starting no power going to the pump until engine turning over Definitely something wrong there. Its very noisy so hardly easy to miss. When you turn the ignition on the pump will prime for when you fire it up. Its quite annoying but will only last a few seconds. Take the car somewhere reliable to check it over and get it up and running properly. Quote Link to comment Share on other sites More sharing options...

Scott Posted April 4, 2009 Share Posted April 4, 2009 just put a test light on the plug and nothing lighting up until engine turning over By turning over do you mean you have the key in the starter motor position or do you mean the car is turning over itself and the key is in ignition position?

wilkorangerover Posted April 4, 2009 Author Share Posted April 4, 2009 (edited) starter motor position should i try the 12v mod?? Edited April 4, 2009 by wilkorangerover (see edit history) Quote Link to comment Share on other sites More sharing options...
Scott Posted April 4, 2009 Share Posted April 4, 2009 starter motor position should i try the 12v mod?? You SHOULD take the car to someone who knows what they are doing. You might end up damanging more stuff. It does sound like there is something wrong with the wiring for the fuel pump though so the 12v mod may sort that out enough to get you to a garage to get it properly sorted.
