TheRecklessEngineer Posted March 18, 2014 Share Posted March 18, 2014 Given that you're getting an unreliable RPM reading and no sparks, it suggests to me that your VR sensor/wiring is at fault. If it's a brand new sensor, then perhaps you should check the wiring closely - especially the pin sockets in the VR sensor connector.

Cynic-al Posted March 18, 2014 Share Posted March 18, 2014 It has to do a full revolution to find the missing tooth to get the timing, my tuner studio has a sync light at the bottom which goes out when it's found it but I can't see it on yours. Maybe that's to do with it? Is the cable shielded? I remember from having Flapper it used to like a fast crank, didn't realise ms liked it too. maybe it's the starter or bad connections from starter to battery. You could try putting a direct live and earth to rule it out and a button for the crank? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 18, 2014 Author Share Posted March 18, 2014 Nige - will do that tomoz morning asap. tuner studio recognises that there is firmware on there (dont know if thats relevant). Not that im doubting your knowledge at all, i just want to learn, but i was under the impression that the edis unit could create a spark without the ms ecu connected or have i mis-read something / got confused somewhere along the line. Reckless - will double check the plug, found in my searching that someone had had a problem with the plug so checked mine and seems to be ok but will double check. Cynic - the cable is indeed shielded. Could be a faulty starter, cable from battery to starter is brand new and something like 10mm maybe 12mm thick so reckon that its not the cable earth to chassis from battery is same stuff. The engine itself has a regular rpm and once the initial spike picked up by tuner studio the rpm stays pretty much the same the numbers dart around between 170 and 200 to quick to read them properly really. All - what do i have to do to generate the rpm graph in tuner studio? got the guage home page bit Quote Link to comment Share on other sites More sharing options...
bobtail84 Posted March 18, 2014 Share Posted March 18, 2014 How have you connected the 'shield' in the shield wire? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 18, 2014 Author Share Posted March 18, 2014 yup, shield wire is connected Quote Link to comment Share on other sites More sharing options...
bobtail84 Posted March 18, 2014 Share Posted March 18, 2014 yup, shield wire is connected Yes... How have you connected it and to where at each end? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 18, 2014 Author Share Posted March 18, 2014 shield isnt connected to anything sensor end, other end shield is connected to a short length of wire into the edis Quote Link to comment Share on other sites More sharing options...
need4speed Posted March 18, 2014 Share Posted March 18, 2014 shield isnt connected to anything sensor end, other end shield is connected to a short length of wire into the edis Onto which pin? Should be pin 7. Quote Link to comment Share on other sites More sharing options...
Chazza Posted March 18, 2014 Share Posted March 18, 2014 Are you sure that the VR sensor is properly connected? Checking the continuity of the wires from the EDIS to the VR connector is not enough, if the pins inside the connector have been damaged by the number of times you have removed the wires. I checked the VR sensor by removing the VR harness and inserting a piece of plastic between the pins, and then connecting two test leads to the sensor. When the engine was cranked a consistent AC voltage was shown on the muti-meter. At this point I finally twigged what the problem was, because I new that I had good continuity in the VR harness, so therefore it had to be the connection between the sensor and the harness that was faulty. Good luck - faults like this can be maddening, Cheers Charlie Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 Fuel Pump is a priming and you have VR signal ^^^ so what he says .... Check the MSQ is in there, open up the VE Tables and spark table 1 and post up !!!!!!!!!!!!!!! MSQs can corrupt sometimes Nige Got VE Table 1 And found 2 tables called Spark table 1 so heres both.

PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 EDIS that i ordered off of fleabay just arrived and we have a spark!!!!!!! now just gotta see if the engine runs :s probably be back in in 5 mins trying to work out why it wont start now it has a spark but there we go.

PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 well i turned out to be right. lol Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 ok, so now i have a spark, the fuel pump is whining away sending fuel, ive checked the leads go to the right plugs, the wires are the correct way round for the coils and the sensor is 5 teeth behind the gap. Any suggestions? or screen shots etc that would be helpfull? Quote Link to comment Share on other sites More sharing options...
Quagmire Posted March 19, 2014 Share Posted March 19, 2014 So what's it doing now? Catching ok and then dying, just coughing a bit, or nothing at all? Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted March 19, 2014 Share Posted March 19, 2014 Sure the fuel pump is plumbed / wired right way around ?....its been done wrong a few times ! Is it trying to start / misfire / sod all ?? Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 everynow and again some glimmer of a cough or bit of a bang but most of the time sod all. lol Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 yer fuel pump is def right way round. fuel is going from high pressure pump thru a pressure regulator if that makes a difference. Quote Link to comment Share on other sites More sharing options...
Hybrid_From_Hell Posted March 19, 2014 Share Posted March 19, 2014 From in tank fuel pump to fuel rail "in" and thenthe fuel return is pipe on the rail with the PRV.....but...have you WIRED it the right way around ?? Are the plugs wet, if they are it will NOT start...been that worn T shirts out .... Quote Link to comment Share on other sites More sharing options...
PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 ok, it goes pipe out of tank --> in line filter --> external pump (only has power and earth terminals) --> pressure regulator --> fuel rail dont think plugs are wet, took one out to check i still had a spark and it seems that i do. when the plugs out at least. lol.

PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 Right tried turning it over again. This time as its turning over it coughs and the rpm drops as though something has forced it to slow down if that makes sense, then it picks back up and does it again. Does that a few time then just carries on turning over normally. Obvs dont wanna turn it over to much incase i screw the starter. lol.

PeteMck Posted March 19, 2014 Author Share Posted March 19, 2014 also noticed, if you turn the ignition on and off a couple of times before starting and get the fuel pump to runs it priming cycle a couple of time it will make a bang when you first crank it but thats the only time it seems to do it. dont know if that helps at all.

Quagmire Posted March 19, 2014 Share Posted March 19, 2014 Sounds like timing could be too far advanced, or ht leads out of order? Quote Link to comment Share on other sites More sharing options...
FridgeFreezer Posted March 19, 2014 Share Posted March 19, 2014 I'm assuming the timing hasn't been properly set / trimmed yet as it's not run, in which case you could probably try with a fixed value in megatune, something like 6 or even 0: (Set "fixed angle" to 0 and "trim" to 0, remember to set "fixed" back to "-10" when you've done tinkering to make it use the spark map) Quote Link to comment Share on other sites More sharing options...
