slow starting 1800

**tony750cc** · 1st January 2010, 17:42

My 1.8 lpg vectra seems to take ages to start from cold. its starting on petrol so its not a gas issue, takes about 15 seconds of cranking before it fires. when its warm it fires up straightt away, havent long had the car so presume it may have always done it. any ideas? car runs fine after start on petrol and gas, battery is charged and has plenty of life. car has less than 50k and is 2005 model. it did throw up a couple of fault codes the other day but have since been cleared and not reappeared. codes were 302 and 100 (cylinder 2 misfire and maf or vaf circuit malfunction)
any ideas gratefully recieved!

You keep it well serviced?

Plugs, leads and coil packs would be my starting point

was serviced in july at 48k by a vauxhall dealer its only done a few hundred miles since then as was sat on the dealers forecourt since august.

as john says leads plugs and coil packs would be a good starting point

may have to try plugs and the pack, i had a feeling the coil pack maybe a bit ropey, i priced up a new one from vx at just over a hundred quid, ive seen aftermarket ones on ebay for about half that...not sure how long they will last though! have had some issues with cheap ones that ive used before. maybe best to put a original one on there.
thanks for the ideas
