Hi Peeps, Got my car back from PPS yesterday and had no problems with the car. It needed a jump start but after 300 miles the battery was fully charged :D.

 

This morning it doesn't want to start. It turns over fine but just doesn't fire.

ConZult Error shows all clear (55).

 

I'm in the process of stripping the coil packs down to check the plugs.

 

Any other ideas of things I can try if I don't find anything ?

ohh crap!!! you must be feeling gutted with all the work you've done.

 

Does the car still bump start?

O s**t hope you get it sorted mate. just my small bit have you checked the fuse. keeping my fingers crossed

 

jay

what fuse ?

Not sure what the hells going on but it looks like the car won't be coming to Billling unless I can get something sorted rather quickly.

 

No, No and thrice, No!

 

Jeesh mate .. you *must* get the car going by Billing - we need to admire Peter's handywork! And you deserve to be able to show her off.

 

All I can offer you is good luck, I'm afraid, as you are well aware, I am a mechanical f**kwit. So, good luck.

After all these posts,your gonna have to see what the car is lacking when it wont start...ie fuel/spark..fuel to the fuel filter dont mean the injectors are opening, at the correct time anyway and just check for good spark when cranking..Had one once do this prob and it was the ignition amp on the front timing belt cover...sounds like ya got a pain in the ass tho.!!!!But bet ya aint surprised with owning a Z32 are ya!!

Also remember that a consult will not check bugger all on the HT side of the ignition,just check what ya can methodically and when ya get to the end of ya tether just give it someone who can throw bits at it!!!Its a crap way to fix a car but these are a nightmare really..1 last thing,,check ya CTS,,this could just be under or over fuelling ya car to death. Its an easy check and just may pull ya out of the shite..if that aint the fault at least ya checked it!!

Good luck.....

It's deffo the spark.

I've got MSN roadside assistance from sparks at the moment.

Swapped the PTU's between each car and that doesn't look like the problem. But sparks is helping me eliminate one thing bit by bit.

 

Hopefully I will get to the bottom of this.

You tried the CAS yet stu??

Stu, mark where yer bolts are positioned on yer cas and swap it over for another one, she's gotta fire up then

Bear in mind this can alter your timing, so WHEN it works check timing is okay, yer need the motor running, how else you gonna show the boys your new hard pipe kit :D

cheers

smithy :cool:

Only just got the hard pipes this morning and I can saftely say they won't be going on the car until my engine is running and cleaned. Which by the looks of it is not going to be this side of Billing.

 

Swapped the CAS over with Cerina's car but still no luck.

'sgotta be that dodgy chip, erm, i mean teapot!! you know anyone that you can swap the ecu with??

Stu,

 

I have complete spare manwell ECU ...

 

Let me know if you need it ... Give me a bell on my mobile, I'll be on conference calls 'til 6, but should be able to answer. Ahh, the joys of a mute button ;)

 

JB.

I'm following this with interest as mine is showing similar symptoms. Fires perfectly one day then not next. :mad:

Never died when up and running. Tried almost everything but intermittent faults are the very devil to sort. Been taken to a local auto-electrician three times and it always works when it gets there.

It will not fire now so it's going back........

 

Yeah, a REALLY useful post.........but u r not alone.

 

That sure is a lot of money you've spent. :eek:

 

Just had polyurethane bushes fitted f&r but dunno whether they've made any difference.

Well after testing each individual coil pack I phoned John-boy and he is going to lend me his ECU. Thanks mate Owe you one.

 

I have taken all the plugs out of the engine so that the excess fuel can evaperate over night (if there is any excess). I will then try the new ECU in the morning.

 

If this works cindaella will be going to the ball ;).

Well, the ugly sisters are already there!

 

Good luck mate, I know how infuriating these cars are when they go wrong........its like a love/hate kinda thing.

Whats the latest Stu?

 

I was thinking if it is the new chip then that might explain why it was ok on the way home from PPS while it was still learning its new parameters and then the next day, once they were established, then your problem began?

 

Anyway, call you in a bit mate.

Well I just fitted the new ECU and the oven alarm should be going on any seconds :D. So my plugs will be ready :D.

 

Was going to test for a spark first but I can't get that dam fuel pump fuse out, and I'm worried that I may break it which is all I need, so I'm going to put the plugs in bolt the coil packs down and hope for the best.

 

 

I don't think this has got anything to do with it, but my new bonnet vent seems to have found a drain in the form of my temp sensor.

You might find it easier to unplug the fuel pump if you can't get that relay out - four screws in the boot under the spare wheel, and disconnect the connector.. Does the same job, afterall.. (ish)

ummm water and electric never a good combo keep us posted mate fingers crossed

I'd love to but !!!!

Right guys,

 

Looks like it wasn't a dodgy T-pot or ECU problem after all. I put John-boys Stock Manual ECU in last week and it seem to sort the problem out, however on Saturday this week the problem reared it's ugly head once again, still with the stock ECU and chip in place.

 

So I'd like to make a formal appology to Chris C. Seems like his T-pot was spot on after all and it was a different problem.

 

I know I have low compression on 3 cylinders due to inlet valves and PR at SE has mentioned that this is the likely cause of the problem. My car is booked in for 30th August for new valves all round, so we'll see then.

 

Once again appologies to Chirs C for any damage to his unblemished reputaion I may have caused.

 

He's still a camp fvcker though :D

Smw1 only just read this thread through and low compression was my thoughts from about half way through, now as you mention it at the end and in particular three cylinders are they all on the same bank? reason I ask is if they are I would certainly check the valve timing of the cam belt, I have seen this many times where an inlet cam jumps a couple of teeth (slack belt or low grade non Nissan one fitted)and the result is low compression on one bank, if however it is on both sides it still could be dodgy valve timing, what compression values do you have ? any hint low compression will cause starting problems but it does need to be on at least two cylinders, what`s the belt history? has it been changed lately? could be on wrong? defo worth a look before doing valves, be worth having a full compression test both dry and wet and see what the figures look like then 180psi is standard figure with no bigger difference than 14 psi between cylinders, having said that have seen some very good performance zeds running in the 130 psi are so it does seem equall figures are more important. I would defo check the belt first though.

 

Hope that helps (you save some money and grief)

LOL I will have to prove my un-campness at next years Billing :o

 

My teapots are of the highest quality and are installed in your kitchen with the greatest of care ;)

Didn't I tell you it couldn't be a faulty teabag? :D

Hi Jeff, the belt was changed by yourself when I first got the car back in November. I have had the belt/timing checked recently and it is spot on. The crank angle sensor is reading 15 Degrees via my conZult.

 

The low compression is on Cylinders 2,3,5 so it's just wear and tear I guess.

The compression ranges from 150 down to 110. so looks like the replacement and reseating of the valves will fix the problems and hopefully increase the performance of the car.

 

I do like to drive hard but I think the problem existed before I even got the car.

Stu, I wondered if you had had any major work since last year that may have required the belt been taken off as you had mentioned valves, can see now you may be right after all, if we have fun driving hard suppose we have to pay some were along the line ..worse luck.

 

Jeff TT

I think this was actually better than a compression test - didn't PaulC do a cylinder leak down test for you? That basically points directly to the problem - compression tests are ok but no good at actually finding the fault IMO ;)

 

CheerZ,
