Help Required (Again)

[Jaye R]

Hi all

Just need to pick all your brains once more...well the S is pretty much coming back together nicely (about bloomin time I hear you cry - only been 5 and half years to date)...so, I decided to try and start her at the weekend and (to no great surprise) she doesn't want to cooperate.

This is what I have done so far...

- Fuel - YES
- Coolant - YES
- Battery Charged - YES (along with a booster pack attached).
- Fuel Pump 'whirring' - YES

Turn the key and the alternator turns (very laboured though), the starter motor clicks, but then everything just grinds to a halt. Pause, try again, same thing. Is stongly suspect it is battery/power related, but could it be lack of fuel (only just put juice in the tank, so nothing in the fuel lines), could it be the dizzy is in the wrong place, etc???

I feel that this might be a trial & error process, but would like some pointers as to where to start the fault finding process.

Even better if anyone would like a trip to Wakefield to help me work this out it would be truly appreciated - usual tea/coffee & biscuits with beer tokens included on offer as bribery If you can, fab - please just PM me so we can arrange an engine 'play date'

Many thanks for all advices in advance.

Cheers
Jaye

Hi Guys

Many thanks for the quick response...no how to show how especially thick I am...below is a picture of my multi-meter...which setting do I set the 'dial' to and which reading am I looking at...sorry, not really used one before



Cheers

Defo sounds like a new battery then If someone can just let me know the correct settimgs & way to read the multi meter that would be great.

I shall try all of the above before sourcing a new battery

Thanks again

Cheers

Ah ha...thanks Mike

[Jaye R]

[Jaye R]

Thanks guys...will let you kbow how things progress...

Hi all me again!!!

Still no joy in starting

- Replaced Battery
- replaced spark plugs
- checked dizzy position
- fuel pump sounds like it runs when I turn the key

Engine turning over fine, just not firing up.

I have a feeling that the fuel is not getter through...the spark plugs are bone dry...

I have ordered a new fuel filter & pump (just in case) & was wondering whether there are any kind souls who fancy a run to Wakefield on Sat 29th or Sun 30th July to help me go through everything to find the fault...I think it's going to be a two man job to work it through.

Cheers

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,
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

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...

Keep us posted

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

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,
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
