Omega General Help / Omega 2.2 2002 replaced head gasket now will not fire
« on: 05 September 2019, 20:36:24 »
I bought an omega 2.2 a few months back. when starting from dead cold it usually was lumpy as if firing on 2 or 3 cylinders but would run OK after a few hundred yards and was then problem free for the rest of the day.
A few weeks back it was hard to turn over initially (one barrel was full of water), a few flicks of the key and it started with a cloud of steam....
I got a mechanic friend to do the repair (I am of the very old school and know nothing about electronic ignition or sensors).
He did the replacement without disconnecting the exhaust and a few other things by tilting the head to one side, he cleaned the block and head and replaced the head gasket.
He did not disturb the coil pack whilst doing this (assuming all was OK).
As the cams had to be removed to clean everything up I checked the valve timing with him and it looked spot on.
We turned it over a few times and it was totally dead, we checked for a spark and there was nothing.
He then removed the coil pack and it was dripping in oil and water (which must have been there from the old leaking head gasket). We cleaned it all up but there was still no spark. He thought the coil pack had been blown by being immersed in the water so i bought a new pack. there is still no spark.....
Although the air box has not been put back on (or the airflow sensor) he said all the necessary sensors are connected.
Does anyone know what else could of happened to prevent it sparking please ?
The car itself has done just over 50,000 miles being a 6 door Wilcox Limousine that had been mainly used for one purpose!
Prior to this happening most things about it looked almost like new, even under the bonnet.
