totay i noticed the camshaft pulley was a tooth out of line with the bottom one and adjusted it,afterwards i started it and it ran for a while but was missing so i shut it down to set up the timing light to adjust the timing,and she hasnt started again,it has fuel and a spark yet still wont start?
any ideas
cheers

so are you saying the timing is correct NOW and it wont start? if so 1st thing to do now is check for compression from all the cylinders as it may have bent some of the valves which was why it was missing b4

bassy_g

shit i hope not
yes it started then after i adjusted it then after i shut it down it hasnt started again.i only adjusted it a tooths worth.it was a great starter before i did this

SafeChav

Are you SURE it was a tooth out before..........

Common sense says to me if it would idle nice before and won't now, its NOW a tooth out.

The CVH is fairly forgiving i got the pulley a tooth out on a N/A engine before and it was ok, just drove like a pile of poo

bassy_g

it looks all lined up now,before i adjusted it,it ran but was a bit lumpy,idled unevenly when warming up,i will get back on it tomorrow and recheck everything is in line with the cambelt.
im really starting to hate this car lol its one problem after another at the minute

SafeChav

Its not uncommon to have lumpy idle, thats another 120+ VAT on the bill to fix

I bet the belt is out a tooth you've got to remember you can turn the bottom end over and hardly notice the difference at the top end.

Get the belt back off, get the bottom timing mark BANG on TDC, then line the cam up, and pull the front edge of the belt up to the cam pulley, is should fit in teeth nicely, if it doesn't something is out of line!

And does you car have a vernier pulley by any chance?

bassy_g

thanks mate i will try that tomorrow,it doesent have a vernier
out of interest what is it that causes the lumpy idle?
im hoping to convert it to efi soon which i hope will make it run alot better
thanks for the help mate

SafeChav

All the valve opening/closing times get altered so it runs shit.

EFI is a good step but i can almost guarantee your lumpy idle on warm up is caused by the brake servo, Ł120+ VAT for a new one

bassy_g

the servo is a bit worse for wear 120 plus vat
will try and get a good second hand one lol

SafeChav

I don't think there is such a thing as a GOOD second hand servo on a MK4, ive never owned one with a good servo?!!!!

bassy_g

true,maybe best to get a new one when i can,occoasionally new ones pop up on ebay,never knew it was the cause of the erratic idling

SafeChav

Can be!

Disconnect the vacuum pipe and block the hole and leave it to warm up, i think you'll find its the cause! The MFI RST's are very sensitive to air leaks.

Craigb

Just to confirm..

The 'V' on the bottom pulley should be at the top (12 o'clock) and the notch on the cam pulley should be at top (12 o'clock) ?

SafeChav

Craigb are you asking or stating?

Craigb

Asking

bassy_g

ok ive been out and redid the cambelt and its spot on yet still wont start?
it is flooding whenever i turn it over,when i remove the fuel pump relay it tries to start and even runs for a few seconds and dies but with the relay in it just turns over and doesent even try to start?

antony215

Have you messed with the dizzy?? and have you put your leads round the right way now

bassy_g

well i got it started and it ran like shite,the dizzy nuts were still loose from when i slackened them ready to adjust the timing,now it wont start again,i swopped the leads and it made no difference,still wont start

SafeChav

Unplug the cold start injector, and there should be a mark on the dizzy that lines up with a mark on the head if your lucky, that should get it started

bassy_g

will try that now,it still seems to be flooding it,it starts arnd runs for a few seconds with the fuel pump relay unplugged but when i plug it in it floods it again

SafeChav

The cold start injector can cause it to flood. Ive had the engines running off the cold start valve alone before, and thats no joke!!

bassy_g

still no joy mate,it absolutley stinks of petrol at the front end and still wont start

SafeChav

You got a camera handy?

bassy_g

yes on me phone what should i take a pic of?
thanks

SafeChav

Take the cam belt cover off, set the bottom end where you've currently been setting it to fit the cam belt, and take a picture so i can see the notch in the pulley and the timing marks. (VERY hard i know but its tough )

And also one of the cam pulley again so i can see the timing marks.

bassy_g

ok mate wont be long

SafeChav

chop chop

bassy_g

ok done it now mate
bottom

top

ht lead arangement and where rotor arm points

SafeChav

All looks spot on to me, i wasnt expectin the bottom pulley picture from underneath, so just to confirm, the pulley is lined up with "0" yea?

However HOW FAR adavanced is your timing

Set the dizzy int he middle, i can't tell if you've got the leads in the right places with the dizzy that far out of adjustment

Oh and buy Windows XP you cheap skate

SafeChav

Looking again, the HT leads seem ok, its just so far advanced, im not surprised it won't start!!

bassy_g

yes its on the o mate,will put the dizzy in the middle then try again

windows xp is far to expensive mate

SafeChav

I know thats why i dont buy it either but shhhhhhhhhhhh

Unplug the cold start valve aswell

bassy_g

i ste the dizzy in the middle and it fired straight up,but was missfiring badly,and wanting to cut out,when it did cut out it refused to start again,gave up for today i hope it catches fire during the night it was a first time starter till a few days ago
i have the cold start valve unplugged
i

SafeChav

It will missfire mate you've flooded it remember.

Start it up, and hold the revs as low as you can without it cutting out, shouldn't take much, and it will soon clear

trust me on this

bassy_g

its too dark to do anything with it now i had it running for about 5 mins but i accidently let it cut out and now it wont start again will have another go in the morning

SafeChav

Its not too dark to go and turn the key

I would of thought it would of cleared in 5 mins, check all the leads are on tight when you re-try

bassy_g

i pushed her back in the yard and put the cover over her lol
and been landed with looking after my niece
will have another go tommorow

SafeChav

Have fun

bassy_g

it started this morining but was still running rough an missing,tried a compression test and have 8 bar across all 4 cylnders? is that ok?

SafeChav

Thats not bad, should run ok.

Take your plugs out and see what sort of state they are in
