Help Required (Again)

Hi Jaye,

Do you have any other dates available?
That weekend is Silverstone Classic, 3 Sisters TVR Speed Challenge sprints, and my local High Peak Nomads monthly meet at Rudyard near Leek.
You may get more response with an alternative date.

Plus I'm no expert on the Efi system but I'm willing to help if I can.
Firstly, could it be an immobiliser issue?
I'm thinking "Is the fuel getting to the injectors? Are the injectors getting an electrical supply? If so, are they physically opening and spraying a good spray pattern?
If it is an electrical / ECU issue, a diagnostic check using a Star Tester would most likely show it up. RayTVR has one, as does Phillpot.
Is there nobody local whose brains you could pick? I believe Damian is good on electronic stuff.

When is your daughter's prom? I believe that was the target for getting your S ready? It must be getting close...

Hi Glen

Clash of dates duly noted - to be fair, I just could do with a spare pair of hands as I run through all the possible diagnostics...so if you fancy an evening run over during the week at some point, let me know & we might be able to sort something (or even during the day as I can easily book an afternoon off from the office).

I think it's just going to be a slow/check everything bit by bit process to try and find the fault...lots of suggestions to try.

Daughter's prom is summer 2018, so hopefully that should give me enough time to get things sorted

Cheers
Jaye

About time!
Agree with the fuel diagnosis from the limited information. Fuel pipes the right way round ?
Have a look for the pressure valve car tyre valve as suggested. Air flow meters connected correctly, maybe try swapping them (connectors) over.
Failing that sorry but don't get up that way much any more. There may be some useful information for someone who knows here though...

Jaye,
To cover all the bases, if you can get Mike or Ray to send you a Star Tester on loan, then get in touch with me; I'll pop over sometime mutually convenient.

I can't promise anything, but two heads are better than one, eh?

Is there anybody else out there near Wakefield with "The Knowledge"?

Hi Glenn - fab, thanks I'm going to fit the new fuel filter & pump first (probably this weekend) as it certainly won't do any harm having new ones anyway. Then go through the 'system' as suggested by others (probably the following weekend)....if all that fails then I shall beg the star tester & get in touch to arrange a get together accordingly.

Cheers

Hi Greg

I would presume the fuel pipes are the correct way round as they are the same ones that came off and were marked up as to where to fit Will have a look at the pressure valve as suggested. Not sure if the airflow meters will affect the original 'firing up' of the engine, if it was bad running then yes, but the spark plugs are completely dry so it looks like no fuel is getting to the 'spark' in the first place

Will keep everyone updated over the next couple of weeks.

Once I get the engine started, it's just a case of sorting the brakes & making sure everything is 'tightened' up. Then I need to do a bit more saving to get a new full set of tyres (as the ones on are nearly 9 years old) - so I reckon it'll be in for it's MOT early spring next year & be good to go

Cheers

As above check the fuel pressure is getting to the rail and the schroder valve.

If it isn't, then fuel pump, filter clogged tank etc as you suggest.

If there is fuel pressure at the rail, plugs will still be dry unless the injectors are being fired by the ECU, which would point more to an ECU/electrical issue.

Hi JayR

last year I needed to confirm my fuel pump was working so I purchased (ebay) a cheap volt meter and also a pressure gauge and sender.

I connected the voltmeter to the +ve connection on the pump so that I could confirm the relay was working fine (suspected it would over heat and stop working)

I fitted the sensor in the flexipipe where it enters the engine compartment and temp located the gauge in the glove box. This confirmed the fuel pressure from the pump.

[Jaye R]

Just a quick note to say many thanks to Ray for bobbing over last night

So, it looks like we have narrowed it down to the fuel pump not pulling fuel through from the tank - although we also think it may be that because the tank only has 10 litres of fuel it there is not enough in there to 'get things moving'...so I will be applying more fuel, retesting and if still no joy the new fuel pump & filter will be fitted...

So, hopefully I shall be returning with some good news in the near future

Thanks again to Ray.

Cheers
Jaye

You should also be sure that those 10L are still "good" fuel and have not been sitting there for ages.

There is a small plastic filter fitted inside the bottom of the tank, where the outlet hose is connected.
Check to see if this is NOT blocked.

[Kitchski]

Yup, check that filter ^^

Also, I'm guessing this is a 2.9? Have you been able to confirm the injectors are actually firing?

Apologies if that's been covered as I've just quickly scan-read it, but even if you're getting fuel at the rail, the injectors might not be being told to open.

Jaye,
I may be able to pop over for a couple of hours Saturday aft if you are in the garage then. I still have a mobile number here for you ending in 394. Is that still good? If not and you want a hand could you pm me a number and will give you a call tomorrow.

Cheers,
Carl.

Hi Carl

That'd be great if you want to pop over - number is still the same one Give me a call first as I've got a couple of 'Dad's Taxi' runs to sort but will be around.

Cheers
Jaye
