Re: Nissan X-Trail Non-start Timing Chain?

I don't know, but it comes across to me like an electrical fault. Because the engine will not start cold with the crank sensor connected, but will start with it connected when warm, suggests to me that resistance of some component is high when cold, thus current cannot flow, but when warm the resist...

Re: PicoScope NVH Useful or Not?

ironmathyu5 Don't be put off that easy with NVH and the scope. We learn at our own speeds and the software produced by Pico for their scope and NVH is second to none, what I mean there is it is first class. There is much data available for NVH and I'd of thought your company would have their own NVH...

Re: wasted spark waveform interpretation

I have one of those cars, mine is the single point injection. I can't remember if Vauxhall did a multi cylinder injection system, although looking at your waveform it appears they did. I can see that the coil current ramp triggers twice and this suggests that the ignition is also triggering during t...

Re: guided tests

Are you using pico 6 or 7?

Six is in the automotive menu at the top. Pico 7 automatically displays guided tests on screen when software opened.

Re: Mechanical Injectors Tests

Ford Transit diesel injector test cylinder 1.psdata I've done some more test using the Piezo directly connected to the injector pipes and a x1 probe. I think it looks like three injectors are failing. I'd appreciate your views. It seems that the forum can't accept the size of the files so the other...

Re: Mechanical Injectors Tests

Thanks Ivor, maybe I misunderstood what Ben was saying, but now I'll try and use the piezo with a BNC lead connected and see what results I can get.

Re: Exhaust vibration??

Hi Curt, I have had a Honda in today for a replacement exhaust system. It seems at the moment that these Honda's are a hot topic as the CATs are very easy to gain access to and steal. We have had two in recently where the CATs had been stolen. Initially I thought a battery powered grinder had been u...

Re: Mechanical Injectors Tests

Was going to do some more testing this evening after work but the Pulse diesel injection unit has now failed. I seem to get no end of problems with equipment. I won't be buying another. What I'll do is look more in detail at the NVH kit and see how I can test the vibrations from the injectors with it.
