dubber92 1 Posted May 15, 2014 Report Share Posted May 15, 2014 just after some advice really, i have a 95 vr6 golf that don't like to start! it's fine from cold but once its warm and then left for afew minutes it takes ages to start! i scanned it and it came up with 00513 engine speed sensor no signal. so i changed that and still no better, when it eventually starts there's no misfire or anything its just like someone flicks a switch! only other thing i can think of is its running a 4 bar fuel pressure reg so maybe its had a remap that it don't like? any help would be much appreciated. cheers. jack.

mattvr6 133 Posted May 15, 2014 Report Share Posted May 15, 2014 Coolant temp sensor Sent from my iPhone using Tapatalk Link to post Share on other sites
dubber92 1 Posted May 15, 2014 Author Report Share Posted May 15, 2014 Would that not log a fault code mate? Link to post Share on other sites
mattvr6 133 Posted May 16, 2014 Report Share Posted May 16, 2014 Normally but not always have u looked at the crank sensor this may be breaking down once hot Sent from my iPhone using Tapatalk Link to post Share on other sites
Bealieboy 1,625 Posted May 16, 2014 Report Share Posted May 16, 2014 Yeah, I'd be looking at the crank sensor on this one. I had exactly the same problem except that mine would conk out once warm too. Sent from my iPhone using Tapatalk Link to post Share on other sites
dubber92 1 Posted May 17, 2014 Author Report Share Posted May 17, 2014 yeah the crank sensor is what i changed but its no different, if anything its worse Link to post Share on other sites
Bealieboy 1,625 Posted May 17, 2014 Report Share Posted May 17, 2014 Could be looking at the blue temp sensor then? Sent from my iPhone using Tapatalk Link to post Share on other sites
mattvr6 133 Posted May 17, 2014 Report Share Posted May 17, 2014 Genuine or pattern sensor? Sent from my iPhone using Tapatalk Link to post Share on other sites
dubber92 1 Posted May 18, 2014 Author Report Share Posted May 18, 2014 i reckon the blue temp sensor will be next on the list but it was a pattern sensor and still brings the 00513 code up Link to post Share on other sites

MJ Vr6 79 Posted May 20, 2014 Report Share Posted May 20, 2014 P.S. Have you a Coil Pack or Dizzy? Link to post Share on other sites
dubber92 1 Posted May 20, 2014 Author Report Share Posted May 20, 2014 its the coilpack model, i have now tried a genuine vw crank sensor and its no different,i have also been told it could be a connecter block on the back of the ignition switch, is that possible? Link to post Share on other sites

dubber92 1 Posted May 20, 2014 Author Report Share Posted May 20, 2014 yeah when its warm its a nightmare, i have unplugged the cts and its no different, im running out of ideas now Link to post Share on other sites
Bealieboy 1,625 Posted May 20, 2014 Report Share Posted May 20, 2014 This surely has to be a sensor breakdown, would camshaft position sensor give similar symptoms to a dodgy crankshaft sensor Sent from my iPhone using Tapatalk Link to post Share on other sites
mattvr6 133 Posted May 20, 2014 Report Share Posted May 20, 2014 Id possible look into checking fuel pressure mate and the relay is there any other fault codes coming out of it?Sent from my iPhone using Tapatalk Link to post Share on other sites
MJ Vr6 79 Posted May 21, 2014 Report Share Posted May 21, 2014 yeah when its warm its a nightmare, i have unplugged the cts and its no different, im running out of ideas nowWhilst unplugging the CTS it should have made a difference.Please check the state of your Plugs too.

dubber92 1 Posted May 22, 2014 Author Report Share Posted May 22, 2014 it sarted no different at all with the cts unplugged, if the plugs were at fault would there not be a misfire? Link to post Share on other sites
dubber92 1 Posted May 22, 2014 Author Report Share Posted May 22, 2014 i have also tried a fuel pump relay, no other codes are coming up, from my experiance with cam sensors if they break downit won't start at all off the key only with a bump, getting to the stage of pulling my hair out now lol Link to post Share on other sites
MJ Vr6 79 Posted May 22, 2014 Report Share Posted May 22, 2014 it sarted no different at all with the cts unplugged, if the plugs were at fault would there not be a misfire?No missfire, Just low spark to fire it up.I had a case where a plug had oil sweeping inn hence why I asked to check plugs mate.Had the same scenario, when cold will fire up on one shot.. When warm was a bit hesitant. Link to post Share on other sites
dubber92 1 Posted May 22, 2014 Author Report Share Posted May 22, 2014 ah right ok mate i will check the plugs out then MJ Vr6 1 Link to post Share on other sites
