escorted Posted June 23, 2011 Share Posted June 23, 2011 Soooooo I have more or less taken delivery on my brothers VL....and it has a problem. It started leaking Petrol from the injector closest to the front of the car. Sent it in to the mechanic next to my work. That injector is fd in the A blah blah blah take it out find 6 new Turbo injectors from australia, get them here get them recond and put them back in and it isnt fireing. Spray engine start down intake and it coughs into life momentarily. Replace spark plugs, fresh fuel etc still not fireing. Options: 1) Place all 6 old ones back in a try one for one on the fucked injector. 2) Persist with new ones 3) Take to auto sparkys and check for pulse on injectors Any Other ideas would be great thanks.

KKtrips Posted June 23, 2011 Share Posted June 23, 2011 Do the old and new injectors look the same? Do they both have part numbers and if so is the part number the same? Quote Link to comment Share on other sites More sharing options...
Jase Posted June 23, 2011 Share Posted June 23, 2011 factory turbo vl with factory computer? was it leaking as in flowing constantly or past the o'rings out etc. just go through all your connections and wind it over with the leads off and the rail out see if fuel squirts out.

KKtrips Posted June 23, 2011 Share Posted June 23, 2011 Jase - if it was flooded that badly then it wouldn't start on ether.. Quote Link to comment Share on other sites More sharing options...
johnnyfive Posted June 23, 2011 Share Posted June 23, 2011 Your mechanic should have something they can check for injector signal, a simple noid light is a very cheap and easy way to rule out that side of things. It seems very weird that it had fuel and now doesn't, at all. As KK said, double check you've gotten the same injectors also. eg http://www.sulco.co.nz/Product?Action=View&Product_id=1214 Quote Link to comment Share on other sites More sharing options...
davidian Posted June 23, 2011 Share Posted June 23, 2011 where abouts are you? i can point you to a good sparky in roskill, one of his boys also knows a bit about turbo VLs Quote Link to comment Share on other sites More sharing options...
escorted Posted June 23, 2011 Author Share Posted June 23, 2011 Car is located at the factory i work at in penrose. The only thing noted about the injectors is a Blue ring on the original ones but only one of the injectors from australia has a blue ring, in saying that i was assured by the person i bought them of that they were "fresh out of a vl turbo" Quote Link to comment Share on other sites More sharing options...
KKtrips Posted June 23, 2011 Share Posted June 23, 2011 Where I was going with my question is the injector impedance can vary between types of injector and if they are different it may be enough to prevent your injectors from working.. For example - there is about 35982375 different types of injector for 4age - depending on an equal number of computer types... Measure the impedance between each terminal on the old ones and do the same on at least a couple of new ones.. Quote Link to comment Share on other sites More sharing options...
KKtrips Posted June 23, 2011 Share Posted June 23, 2011 BTW this is not an exercise to see if the resistance is correct - its more to compare the old injectors with the new and see if they are compatible with your computer. As long as the new ones are the same/similar to the old ones then I would say that the injectors is not the problem. (seeing as you had them overhauled) Quote Link to comment Share on other sites More sharing options...
escorted Posted June 23, 2011 Author Share Posted June 23, 2011 Checking this now^! All 6 original are 2.3 ohms Quote Link to comment Share on other sites More sharing options...
KKtrips Posted June 23, 2011 Share Posted June 23, 2011 The tension mounts - what are the replacement 6?? Quote Link to comment Share on other sites More sharing options...
escorted Posted June 23, 2011 Author Share Posted June 23, 2011 Same amount of resistance. Hmm. Perhaps crank angle sensor? Quote Link to comment Share on other sites More sharing options...
KKtrips Posted June 23, 2011 Share Posted June 23, 2011 Next I would check that you are getting a signal to your injectors when cranking. As J5 says - get a noid light suitable for your injector and crank it - the noid light will flash in time with the injector pulses if it is working (an LED put the right way round will work in place of the noid light) Quote Link to comment Share on other sites More sharing options...
escorted Posted June 24, 2011 Author Share Posted June 24, 2011 Used an LED to check The pulse and yes it has a pulse. Went to the auto sparkys to book it in. Any other suggestions? Quote Link to comment Share on other sites More sharing options...
Jase Posted June 24, 2011 Share Posted June 24, 2011 so it coughs on ether?, have you checked spark across all plugs? only reason i say that is my vn and yowzers suffered similar spark related problems, mine the female side of the coil plug was loose as and would make it die intermittently and yowzers just ran on five from dying coil packs. it should be a simple fix if it was running before the swap, are all the injector plug pins making good contact when they're plugged in?, i put vivid on mine to see if it wore off when it was plugged in to the female socket, had one loose socket that i tweaked with a small pin and problem was fixed.

Jase Posted June 24, 2011 Share Posted June 24, 2011 also unplug your ecu for 5 minutes then retry starting it. Quote Link to comment Share on other sites More sharing options...
escorted Posted June 24, 2011 Author Share Posted June 24, 2011 Thats a good thought on the injector plugs and Unplugging the ecu. Will try that tonight Quote Link to comment Share on other sites More sharing options...
FLAWLES Posted June 24, 2011 Share Posted June 24, 2011 rb30ets run an afm do they not? i would be ckecking that to begin with or at lest the conectons, cant remember if they are a hot wire afm or what ever they are called, and are they not also elec dissy? also, this will be zero help as i cant remember exactly what i replaced on this, but my douche bag brother has a rb20e, that did the exact same thing, had fuel to fuel rail, had spark but very very week long story short it was one of the fuel/injector opening relays was sticking, not doing its job fantastic cars mate had a ex ozzy police interceptor vl, was rapid fast hope that helps in some way Quote Link to comment Share on other sites More sharing options...
escorted Posted July 5, 2011 Author Share Posted July 5, 2011 Great sucess. Injector pulse was too weak to fire. So ended up unpicking the loom and finding the supply to the relay has a slight break in it. Little bit of solder and hey presto its alive. Thanks for all the help and suggestions!
