NOT SOLVED - occasional clicking noise accompanied by power loss on acceleration during turbo onset

Been lurking on this site lots & happy to finally have something to contribute. I believe this is worthy of a new thread as I couldn’t find anything matching my symptoms:

As the title suggests, there were worrying noises coming from the engine bay when the turbo kicked in. It’s also worth mentioning that every time this happened I had an ungodly amount of thick smoke coming out the exhaust.

Good news: it’s not the timing chain.

Better news: it’s the low pressure fuel pump located under the rear offside wheel arch (back right). Part cost £35 from eBay. The new one is very noisy, making a good buzz when priming. This makes me happy as I now have a stimulus to alert that it is indeed working!

Bits done before fuel pump included:

Fuel pressure sensor
Injector seals replaced & injectors cleaned
Intercooler & pipes removed & flushed
Air temp sensor replaced (surprising what a difference that made)
Oil & filter service

A bit more info about the diagnostic process:

I thought I’d fixed it after reconning the injectors, however in hindsight the fuel pump must have been working temperamentally.

A pessimistic and fearful part of me feared a turbo issue as the symptoms (smoke, clicking and power stutter) always happened under load when the turbo was just starting to hit high speeds, however I could still hear it spooling up below 1,500 so figured, hey, that’s healthy enough… then something in my head clicked: when a turbo kicks in, the engine needs more fuel to compensate, if the injectors are freshly serviced & I’ve put a new fuel pressure sensor in… maybe they aren’t getting enough fuel? So looked on the forum and found some vaguely similar descriptions of my issue & only saw one or two comments / anecdotes relating to the fuel pump, but decided it was worth a shot and here we are back in ship shape at 161,000 miles.

I hope this thread can help someone else out who may or may not be about ready to “get the damn thing fixed and just bloody sell it”. Because now that she is back on form i’m back to being tremendously charmed by what the freelander 1 has to offer!

Best wishes all

A £35 LP pump from ebay? I'm keen to see how this goes. Would be great if you could keep us updated on reliability/ pump life. I bought a Peirburg a while ago as I always like to buy "good" parts, but it's mega noisy and makes me feel like it's going to let go any time soon.

Yes - let us know about the pump. What brand was it? Seems awfully cheap.

Here is a link to the fuel pump that I purchased, as requested. It’s only been a week but so far so good!

So as the new title suggests, this issue has come back strong. Given the temperamental nature of it I am going to have a crack at changing the turbo boost solenoid. In hindsight, I think this issue began after it had a bath whilst doing some serious off roading. Won’t be doing that in my work horse again… Fingers crossed, will update in a few days.

Ah hope it gets sorted, water causes so many issues it's not fun. May have to get a new work horse and keep this one for play time.

Have you hooked it up and read the live data?

It’s ran okay intermittently since so I’m hoping it’s not the case, although I believe it may have chewed up and spat out some H20 on that fateful day. Still waiting on parts.

I haven’t got the software nor “a guy” for that at the moment, unfortunately! Would you have any suggestions?

Well it looks like you have the FL1 bug, so you really would benefit from your diagnostic tool if you intend on keeping it and doing some fixing. Use it a couple of times and you’ll have recovered the cost.

Personally, I tried the off-the-shelf readers at first, like icarsoft, which are a bit hit and miss with the data they can ‘see’. Ultimately, I got the Pscan, and would say that it’s by far the best I’ve seen in terms of data access for the FL1. Philip (the guy who makes them) is on here, but this is the web site…

Update:

Whilst waiting for my new solenoid to arrive I decided to test the car running on 3 injectors.

With injector 1 (far left) unplugged, the car revs through the range without smoke nor splutter.

With any other combo of injectors plugged in, the car won’t rev past 2k.

Does this point to injector 1 being a leaky mcSneaky? Stay tuned to find out
