suprab Posted January 6, 2011 Share Posted January 6, 2011 Hi all, looking for some advice or things to check/test please. my Jspec has AEM, BW 91-79, 264 cams and 650cc injectors. it starts fine when cold, once it warms up it cuts out and will not restart untill its left to cool down again. i am getting a spark, i have fuel pressure and have rpm on cranking when looking at the AEM with the laptop. Ryan was also helping over the phone but still no joy yet Anyone have any ideas?? Quote Link to comment Share on other sites More sharing options...
Ryan.G Posted January 6, 2011 Share Posted January 6, 2011 Just so people know this has only just started happening recently so not a mapping issue. Things checked - Fuel pressure - Crank Signal to ECU - TPS sensor - Water Temp sensor Plugs are dry and have tried putting more fuel in on crank through aem but makes no difference so currently thinking its another issue with an aem as im told the spark is not consistant either.

DodgyRog Posted January 6, 2011 Share Posted January 6, 2011 I had the same sort of issue with a Seat Toledo, it turned out to be the coil packs Quote Link to comment Share on other sites More sharing options...
suprab Posted January 10, 2011 Author Share Posted January 10, 2011 Bit of an update on the testing. ok the car starts fine from cold, ticks over and revs no problem until the engine warms up. it then cuts out and will not restart until it has cooled down for about 15 mins. once it is not starting i seam to have no spark on cranking for about 4/5 seconds then it will spark for 2 secs then none again for 4/5 and so on. both cam sensors have a reading of 1.4k ohms and the crank sensor about 1.2k ohms according to my findings these should be ohms and not k ohms so maybe someone can confirm?
