wont it start now???

2wd saff cossie. turns over fine, there is fuel, and there appears to be a spark coming from the leads, cleaned all the plugs up. timing is all ok.

sorta sounds like there is no compression

any help wud be gratefully recieved as i had to drive my mums 1litre 3 cylinder corsa to the PF meet last not and i did not enjoy it in the slightest lol

cheers

 

Check the fuel cut off in the boot mate,might have trigered it self

Boost Mad, what did you do to the car just before it stopped working?

 

right, it is fueling,
as for what i did, nothing, new bolt in alternator, exhaust down pipe back on and then it started, all was fine, went to start it allittle lata and now this


mate has just come round with a compression tester and guess what

no compression on any cylinder... oh fuck

 

No compression SHIT !

 

Strange to suddenly have no compression on ANY cylinder... but if you say it spins over with no compression...

To get an idea of what no comp turn over sounds like, spin it over with plugs in and plugs out each should sound different...

you sure belt hasnt stripped, take belt cover off, see if crank rotates aswell as cams..

 

everything turns over fine and its all timed up ok.

"compression tester says NO"

didnt even move the needle

 

does it defo spin over sounding like no compression?

You sure tester aint fudged.. cylinder leakage test see where its going IMO

 

the tester is fine. normaly u can hewar the starter sorta fighting against the compression of the engine but u can now, hard to discribe realy. its the fact that its on all cylinders tho

i obviosly cant move the car

 

try it with plugs in and plugs out see what difference to spin speed sound etc

 

Fingers crossed for ya mate

 

cheers, dont sound alot different to be honest mate, u can hear alittle air escaping from the plug holes but not alot at all, would barley move a piece of paper

 

maybe bent valves somehow.. but check real obvious things before taking head off

 

ive checked most things but what else do u think i shud check

 

have the hydrolic tappets jacked out ....did u start it then turn it off fairly soon ...sometimes oil getup into tappets but cant release pressure holding valves open ...try crancking full throttle and hope for the best i recon it shud go ... i presume belt is driving all the gears

 

yep beltis ok,not to tight or loose either. timing is all at factory stardards. i have tried the cranking on full trottle with no results unfortunatly.

if the teppets had done that widnt the pistons of hit the valves?

 

if you dont have valve cut outs yes

 

well its stadard so it defo aint got ne of those, unless its made some with the valves lol

 

i dont recon it wud .. u do have a bit of clearence zetecs are always doing this

 

are you sure cams are turning when starter is winding,have seen teeth come off belt so bottom pulley turns but belt doesnt if you know what i mean,very strange to have zero compression all of a sudden

cheeRS stu

 

i get loads of callouts to people who start up and pull of the drive then switch it off then they dont start ..is your concern anything like this

 

yeh, i just moved it across the drive abit.

i no from a past experence that the valve will hit the valves.

and i do no that the cams are turning

its so confussing

 

i recon its jacket out tappets .... how long have you cranked it for with full throttle

 

have done it for about 10secs once or twice. nice pop when i tried it again this morn lol.

i realy dont no about the tappets as im no from past experience that the valve WILL hit the pistons. either way its not going anywhere soon as i dont have the money to do it

 

i went to an almera tonight same thing ...cranked for about 30 secs before it fired up....i wud persevere it may save u money

 

Don't know if this will help but had same problem on a few injected cars.
When you start car it goes into cold start mode and puts extra fuel in for cold eng. if you switch off to soon it washes all oil off the bores.
Then every time it doesn't start after its still putting in to much fuel.
no oil on bores no seal for rings = no compression.
Cure... Remove plugs pour some eng oil down each bore, crank eng over with out plugs few time to remove excess. Replace plugs and after a few cranks should start and have compression back
Let me know how you get on.
Don't panic yet.

 

Worth a try for defo!!!

 

dont know if this will help but when i first bought my 2wd cozzy i gave it a good clean under the bonnet then it wouldnt start. tried everything plugs,leads,coil all that stuff turned out the ignition amplifier wasnt clipped in right. started first time afer that.

 

any news yet fella?

 

nope, i havnt had a chance to get round to it... if i get the time i will do the oil in the bore idea and let u no... cheers for asking

 

I had a very similar problem with my 2wd. It drove fine, parked up then tried to start it later no joy. Got a mate who is a mechanic to take a look and at first glance everything seemed to be fine, but all became clear after a compression test. No compression in to cylinders. On closer inspection the woodruff key had snapped, so it looked like the belt was turning everything, but in fact it was only spinning the pulley on the outlet cam not the cam itself. Head off to find bent valves and dings in the pistons. The replacement woodruff key was only 11p. I can laugh now, but different story at the time.
