Jake : Hi there, sorry your having issues
Jake : Now hard starting is fairly common with crank/cam sensor issues. So replacing them was not a bad idea.
Jake : The thing that sticks out here to me is that you need to jump start the vehicle.
Jake : Now a faulty crank/cam sensor or a stretched timing chain wouldn't require a jump to start
Jake : The long cranking with those happens because of the sensors detection of engine position causing the glow plugs not to heat up.
Jake : Your situation on the other hand looks more like an amperage issue when cranking if it requires a jump
perhaps I should clarify, I need to jump start because the battery, when fully charged goes flat before the engine starts, there are no issues with the battery.
Jake : Wow your cranking it THAT much?
Jake : thats ALOT of cranking
Jake : you don't have codes do you?
Jake : for intake advance or anything like that?
no codes from my gear or the Nissan dealer
Jake : What about puffs of smoke on initial start?
when it eventualy starts there is some smoke but very little
Jake : does it run ok once started?
yes runs well not lumpy & ticks over ok
Jake : what about fuel, is the system staying primed?
Jake : simce you verified the glow plug circuit was initiating
Jake : were the plugs wet on initial crank?
when it does start it happens suddenly you think its never going to start then bang its off . yes the fuel is definatly up because it has a hand primer ant you can feel the pressure when you go to start after priming no change.
I have not checked for wet glow plugs after trying to start
Jake : Thanks,, this is a bit of a doozy I understand your frustration
should the glow plugs be wet after all that cranking ?
Jake : Yes
I will go and check should I log off?
Jake : you don't have to
Jake : they should at least smell like deisel
Jake : just reply when you get a chance
taken no 4 glow plug out and its dry
Jake : Are you getting an injector tick when cranking?
don't know but battery flat. now, I have taken the other 3 plugs out and there is signs of diesel towards the top of the element nothing like a wet spark plug .
Jake : Is the security light on solid when cranking?
can not find a security light, where should it be?
is it on the left of the dash by the r/h demister vent if so it does not light even when cent locking is operated
Jake : A little red car with key
My owners manual says the light is on the drivers side vent it is not lighting at all
have removed the bulb and holder from the dash and tested the led with a meter & it seems ok but does not light when in the car
I am going to let the battery charge up over nite and check out the security system, will come back to you
Jake : I'm sorry, I was in church so I put my phone up when it staryed
Jake : started
Jake : But I will talk to you some more tomorrow
Jake : thank you
fixed the security light it was the led after all checked with the user manual and it is working as it should
excellent, that's good to know
since NATS will prevent injector pulse
have you any further thoughts on the non starting?
at this point I would just solidy the whether or not its a fuel or glow plug operation issue
by using a little starting fluid on initial start to see if it fires up
then we can safely assume the glow plug circuit is getting cut
from the cam/crank reference signal interuption
I will have to go and get some, I assume you mean good old easy start.
yes, that will be fine for the test
of course it will be lean and hot, but were not running it on it
just seeing if it will start
Hi Jake got the fluid squirted it up the air intake after the heat cycle had finished, think I overdid it the engine started and rev'ed quite high for a few seconds then came down to tick over.I then then turned it off before it warmed up , when I turned the ignition on again the management light was on I restarted the engine & it seemed to be in some kind of limp mode would only rev to just over 3 turned it off and went for my computer pluged it in light on but still no codes just for the hell I pressed wipe codes turned the ign on & then off, tried to start but it wasn't having it, another smaller squirt off she went light still on, turned it off, So I scratched my head & put away the computer, went back turned on the ign light is off car starts and runs normally While I was under the bonnet looking for some cause of the limp mode the ign was on and the engine not running I noticed a small rattle that seemed to be coming from injector pipes / fuel rail, not doing it now the lights off.Did I mention that the ABS & 4wd lights are on I assume this is not related to the engine fault. well that's it for now hope this gives you some ideas. thanks Dave
Jake : Thanks Dave, that is certainly peculiar from just a little shot.
Jake : The ABS issue will not effect starting, your are correct
Jake : One thing we know this is its a fueling issue at start
Jake : we know the glow plug circuit is working.
Jake : Which makes me wonder if your crank signal is
Jake : effecting injector pulse while cranking
Sorry you lost me now where do I look some kind of voltage drop?
Jake : You need to check for injector pulse
Jake : or
Jake : you can't get an accurate voltage reading at the crank sensor because it uses a wave pattern.
thanks I will do that.
Jake : Your welcome
Sorry Its been a couple of days but I have Been waiting for an auto electrician friend of mine to find his noid when he found it it was the wrong one so I borrowed his led test kit instead & checked no 1 injector plug. On cranking there was one flash then nothing I did this 3 times so I think it is safe to say there is little or no pulse on cranking. When the engine is running there is a regular pulse.
Jake : Thanks for the update. Ill will witk
Jake : work with you on this some later today.
Hi Jake tried to get you a few times what is the best time to try. Dave
Jake : In 3 hours would be great if you can do that
sorry Jake got Man flu & did not care about Nissans.. Had a thought is this a relay or perhaps an ignition switch fault?
