Selah83 Posted February 12, 2015 Posted February 12, 2015 Hey all, thought i'd bring this one to the masses, as to see if i can't get few ideas about this issue I have.. Ok Before Christmas was driving along admiring myself in windows when the car coughed, backfired and stalled.. restarted 10mins later with the CEL light on. Christmas eve drove to in-laws and both traction and slip lights came on adding to the already on CEL light. Tried to start car with no joy just cranking. Early new year had AA out to tell me I had code P0340 - So I replaced both CPS's tried to turn over - again just cracking, then battery died went flat. Next day replaced battery tried to start car, had it running for 2 mins (rough idle) before lots of popping (presume backfire) and stalling, tried restarting a few more times then fried starter motor :/ replaced starter motor and now back in the same position as before - cranks but no start! any ideas??? Cheers Quote
MCook Posted February 12, 2015 Posted February 12, 2015 (edited) Can you hear the fuel pump when you turn ignition to on? Or is there a smell of fuel when it is cranking over? Edited February 12, 2015 by MCook Quote
Selah83 Posted February 12, 2015 Author Posted February 12, 2015 I think the fuel pump is ok, and can definitely smell Fuel Quote
Randy_Baton Posted February 12, 2015 Posted February 12, 2015 (edited) I'd blame the previous owner of that car And like that he's gone. Edited February 12, 2015 by Randy_Baton 1 Quote
ZMANALEX Posted February 12, 2015 Posted February 12, 2015 Providing your cam sensors are okay, I would be perhaps looking at the crank sensor. Alex. Quote
Selah83 Posted February 12, 2015 Author Posted February 12, 2015 wouldn't the crank sensor also throw a code? Quote
ZMANALEX Posted February 12, 2015 Posted February 12, 2015 wouldn't the crank sensor also throw a code? Not necessarily. However if you have replaced the cam sensors properly with proper fully working sensors, then my next port of call would be to try a crank sensor. Where did you buy the cam sensors and were they genuine Nissan.? Quote
Selah83 Posted February 12, 2015 Author Posted February 12, 2015 (edited) Given one by Keyser, the other from Flea-bay - however (that one) I only replaced because I was replacing the faulty one under the intake! Worth putting the old bank 1 back in? to see if that makes a difference? Edited February 12, 2015 by Selah83 Quote
ZMANALEX Posted February 12, 2015 Posted February 12, 2015 As per my first post, I would certainly make sure that both your cam sensors are good, however I know that Keyser would not sell you a duff sensor deliberately, but you always run the risk when fitting used sensors. Alex. Quote
Selah83 Posted February 12, 2015 Author Posted February 12, 2015 Job for the weekend then! Cheers Alex Quote
Selah83 Posted February 16, 2015 Author Posted February 16, 2015 (edited) Ok so an update!!! So i have the front of the engine off and in bits yay I have replaced crack sensor and cam sensors.... Now here is the fantasic bit of news.... looking at the timing belt tensioner, its at 22mm.... well surely that can't be good!! Next step any advice? thanks Edited February 16, 2015 by Selah83 Quote
ZMANALEX Posted February 16, 2015 Posted February 16, 2015 (edited) There is no timing belt on the VQ35DE only a timing chain. Post up a pix of the 22mm issue. Edited February 16, 2015 by ZMANALEX Quote
Selah83 Posted February 16, 2015 Author Posted February 16, 2015 Aye yeah sorry, I could clearly see a chain haha not a belt - well I could see one big ASS chain and 2 smaller chains top left and right.. I'll get a pic in the morning as all locked up in garage now. Cheers Quote
Selah83 Posted February 17, 2015 Author Posted February 17, 2015 Hey Finally managed to take that picture of the tensioner! Quote
ZMANALEX Posted February 17, 2015 Posted February 17, 2015 That bad boy is nearly ready to drop out. Replace the 3 x chains, tensioners, slippers and chain guides. Get the kit from USA at half UK prices. Alex. Quote
Selah83 Posted February 17, 2015 Author Posted February 17, 2015 Just before I do so - need to check if this is right... don't want any boo boo's http://www.ebay.co.uk/itm/Fits-Nissan-Altima-Maxima-350Z-Murano-Infiniti-VQ35DE-V6-DOHC-Timing-Chain-Kit-/360880614113?pt=Motors_Car_Truck_Parts_Accessories&hash=item5406292ae1#shpCntId And again Alex, Thank you Quote

Selah83 Posted February 17, 2015 Author Posted February 17, 2015 and bought!! will take pics of the repair and let you know how it goes - excited now might be able to do another 125 miles before something else falls off!! haha Quote
Keyser Posted February 17, 2015 Posted February 17, 2015 I am amazed - engine has not even done 10K since rebuild - be interested to know why it has gone that loose that quick. Good find though hope it solves your issue Quote
Selah83 Posted February 17, 2015 Author Posted February 17, 2015 (edited) Well to be honest Keyser, when I finally got it up on my mates lift there were a few things i was umming and arrring in about- the supercharger down pipe wasn't connected to the pipe that connects to the engine also the rad fans weren't connected!! :/ - anyway has been a good chance to get under there, clean and look around, try and get to know her a little!! so far her name-sakes has been true but maybe i can tame her a little There is one thing I wanted to ask about whilst on the subject - obviously she's had a new starter motor, however placement of the starter is within 3mm of the manifold (are they legal btw keyser?? lol) is there anyway to shield the starter from the manifold or any ideas about how to go about reducing the amount of heat the starter is gonna be exposed too? Edited February 17, 2015 by Selah83 Quote
Keyser Posted February 17, 2015 Posted February 17, 2015 Well to be honest Keyser, when I finally got it up on my mates lift there were a few things i was umming and arrring in about- the supercharger down pipe wasn't connected to the pipe that connects to the engine Well if that blew apart it may be why she was running rough - boost gauge should have shown no pressure and I'm sure you would have felt the difference if she wasn't making boost ?? It was connected the last time I drove her - trust me I would know if she was not making boost also the rad fans weren't connected!! :/ They are on bullet connectors or were - good job you didn't over heat her - no idea when they were disconnected - I know she had some body work done between leaving me and going to you - but I see no reason to disconnect them to take the bumper off - unless they were in the way when the Z speed under tray was being removed / refitted. - anyway has been a good chance to get under there, clean and look around, try and get to know her a little!! so far her name-sakes has been true but maybe i can tame her a little There is one thing I wanted to ask about whilst on the subject - obviously she's had a new starter motor, however placement of the starter is within 3mm of the manifold (are they legal btw keyser?? lol) is there anyway to shield the start from the manifold or any ideas about how to go about reducing the amount of heat the starter is gonna be exposed too? You mean the manifolds or the decats? All depends on your emissions the headers do say "for race use only" but that is because they are American, on a car that age you can remove CAT's as long as the car will pass emissions - or so I believe, check with an MOT centre - of course I used Hi Flow CATs for the road and only put on the the De-CATs for track Yes the headers are very close to the starter motor - always have been - never had an issue with it, never had to replace a starter motor since the rebuild, they are ceramic coated which should help keep the heat inside - if you want to go another step you could wrap them and if you are really keen you could fit a small plate between the starter and the header to reflect heat - as I say never caused me an issue though 1 Quote
Keyser Posted February 17, 2015 Posted February 17, 2015 Just another thought - if that down pipe has been off since you owned her - boy are you in for a treat when you get her running again : 1 Quote
Selah83 Posted February 18, 2015 Author Posted February 18, 2015 I thought she was running rich! and i think now i understand why!.. she really didn't feel that down on power however moving from a 240bhp Supra to a 350z i was gonna notice some difference Quote
