My 1.2 8v Merit Corsa B wont start. I came home on christmas eve in the car worked ok. Didnt use it at all christmas day then come to fire up on boxing day it turned over but wouldnt fire i thought i didnt have enough petrol in so i put 5 litres in tried again it turned over but no fireing. So i took all spark plugs out cleand all of em and the HT leads i have a spark and there is fuel but still wont fire any ideas?

try holding the accelerator at about 3 quarters while turning it over, see if it coughs (fires on the one cylinder, maybe 2)
if it does start & is very lumpy (sounds like firing on 3 or 2 cylinders), do a compression test - could be headgasket gone between 2 cylinders

also check the spark on each of the 4 leads

Another one to check is the MAP sensor - there is like a tube going to a little block attached to the bulkhead to the left of the coolant tank (facing the car) this failed on mine once & the engine wouldn't start, just check the tube going to it & make sure that its plugged in ok - it never registered on the ECU when mine went, but it did stop the engine from running even though like yours it was getting fuel, sparkin and turnin over

ok so uve got spark... the next essential thing for an internal combustion engine is fuel 
then maybe try a compression test if you have a compression tester?

Could be starter motor or ignition coil

this is exactly what has happend to mine over xmas too. 1.4 SRi though. It has lost all compression, sounds like it is gonna start. If u put ur foot on the accelerator it coughs but wont start. i did get it sort of started from a push start but is sounded bad and lost all power.

mine was doin this intermittently for a while then just before xmas it wouldnt start at all. Was turning over but just wouldnt fire up.
I ended up turning it over too much and the starter motor broke.
cost me £60 ish for a new one and fitted it my self - starts and runs fine now.
Starter motor is a bastard to fit though when youve only got the standard jack and one axle stand  god i wish i had my own garage sometimes.

It was running fine but i think the exhaust was blowing as the week before xmas i had sorted the exhaust out as it was noking on my axel i forgot to put exhuast putty on the jojnt of the back box so i think it was blowing. Apart from thst iot was ok, I have had a mobile mechanic out tjis morning he found the that distiributer cap and the rotor arm ware fucked i aint no mechancic lol so he is coming back soon with a new one maybe it will work i dunno. I will give more detaisl soon
thanks for the replies

as i said before theres alot of moisture around this time of year even if you are getting a spark it only takes 2 mins to wipe out the distributor cap and roter arm but getting a new one fitted wont to any harm
I started my 1.2 8v merit on the day after boxing day and it sounded like it was running on 3 cylinders even cut out on me. Done what i said above and shes hummin sweetly again(well as good as an 8v gets
