I had a prob over weekend of car wouldnt start. I thought it was starter... but its been in garage and it aint.. its a fuel prob. it just doesnt wanna start.
could this be because the CO was turned down for the mot?

or could it be something like the fuel relay? but the pump seems to prime when ignition is switched on.

any ideas on what to check as the garage at work are a truck garage so not used to old cars. lol

cheers guys

Rick

Yes, probably everything to do with the fuel being turned down. They are very sensitive, buy you still get her to idle below 3.5% Get someone to crank the car, and u gently press down the metering flap, and see if she starts.

scottbrown

cheers will try that.
also what is the green plug on the side of the inlet as the wiring to it is shit.. would this affect starting??

cheers

HORNETS7

the green plug is the knock sensor for the ecu ! yes it should start with the wiring dodgy but u should replace it

Rick

effects the car on boost, shouldnt harm starting at all

scottbrown

right that didnt help although sounds like battery might be flat now..doh.
so cant tell for sure.

has anyone got any close up photos of the metering head as i seem to have a red cable off the metering head with a loop on the end not connected to anything. could this be part of prob?

I also have a plug which is like a t piece connecter and a brown and black wire coming out of the coil loom not conected to anything and cant see anywhere to connect it too? any ideas? cheers

Rick

u got a pic of urs?

and what didnt help?

scottbrown

pushing the flap while cranking car over. but like a say batt i think is not great now.
hold on pics coming

Rick

you only need to press the flap a mm or so - more will flood her.

scottbrown

ha ha that might help.

pics uploading now.

bear with me

scottbrown

pic of red pipe off metering head not connected to anything.



pipe brought into open for a better view

brown and yellow wire with a t plug on it, also not connected to anything




general engine picture incase there is anything you clever peeps can see


cheers

scottbrown

any ideas guys?

cheers

Rick

its hard to see. The multiplug is off the amal valve, which prob isnt used anymore - wont effect the starting thats for sure.

The fuel line - where does it lead to? There should be 3 rings connected to the sides of the metering unit - 2 large, one small. I can only see the one coming from the fuel filter on the pic.

scottbrown

its the line on the top right of the metering head


if you are looking at the 4 lines in a square on the top. its top right.

scottbrown

tell a lie... its the red line coming out by the red block above the 4 red lines in a square pattern that is not connected to anything.

Rick

the one with the unconnected ring comes from one of the top 4 outlets?!! They are injector lines.

scottbrown

no sorry.just above the four is a red block in the photo. there is a red line connected to the metering heah here but nothing connected the other end of the line.

Rick

Here is mine. THe three ring positons are arowed.

scottbrown

here is mine. its the line circled and connects just out of pic. yours doesnt seem to have this

scottbrown

it connects to the metering head underneath the red block. the other end has a ring on it but is not connected to anything

Rick

u have a fuel computer don't u?

scottbrown

no.
it may have done once. but not anymore.
is that what it is?

SafeChav

The red block is the fuel flow sensor for a fuel computer, as Rick is probably typing right now

First things first get rid of that shocking dump valve and see if it starts then.......

Rick

to be honest, its really hard to tell, but it might be a fuel flow meter. As long as the metering unit has all the connections on, and the cylinder shaped object has it's three connections on (underneath and to left of metering unit), it should be fine.

U need to crank it and press the metering flap just very slightly to see if she fires or tries to. To test if fuel is going to the injectors, undo one of the 4 top banjo bolts. Press the metering flap, and crank - fuel should piss out.

scottbrown

lol. just bought a bailey one off tiff but not here yet. that was on car when i bought it.

SafeChav

Right on cue, FUCK IM GOOD

scottbrown

cheers rick.

will try that tommorow.
thanks

Rick

SafeChav

Everything rick is saying is good advice so far, but if it was me 2 things i would do, is check the flap bobs up and down slightly when cranking (if not you have an air leak) and if it doesn't remove and block off the DV and try again

Rick

Have a look where the speedo cable joins the gearbox - is there a connector thing there? If there is, its for a fuel computer and i want it

SafeChav

Rick: how many speed sensors do you want? 5? 6? possibly 7?

Rick

cant help thinking MOT monkey has leaned it off to 0.1% CO so she no longer starts....

Rick

just the one....

SafeChav

You're probably right

Only one No bulk discount for you then. Have you got the proper loom for it aswell?

scottbrown

according to mot sheet. fueling failed 1st time at 5% nd then passed at 0.6%co. is this too low. if you post a pic of what the connecting looks like i will have a look for ya

SafeChav

That is very low............

Sounds like he just gave it a good twist and..........yeah that passed (no concern about how it runs from there-on)

Rick

Yep. Too Low. They've turned it down too much, and now she won't start.

Andy - no i haven't - and id v much like one.....

scottbrown

so if i take it back to a garage and get them to turn it up that will help.

what should it be ideally at idle so that i can get it running to get it down to interpro for a set up?

SafeChav

If i were you mate i'd give it a tiny lil tweak yourself so it runs again and then take it for a very slow and non-boosting drive to interpro, if hes doing random adjustments like that then im fairly sure u can aswell, its just important you drive it sensibly and it will be fine

Rick

if ur going to interpro, they'll sort it - u just need it running right. Aim for 3% as a starter. If u like, you can give the CO screw 1/8 a turn clockwise with a 3mm allen key, to richen it, and see if she starts.
