Dear enlightened one,
I have just bought an SRI 1.8i 1986 convertible (£400!!) new mot but been standing for 3 years. It seems clean enough, starts/ runs quietly, dry engine. However, first trip, covered two miles and the ignition suddenly switched off (inc revcounter) all other electrics OK. After doing a short `frustration dance` I tried again - it started first go and drove straight home and just as 2 miles came up again, it started catching again, but got me home. I cleaned the obvious elec contacts/ earths, and went for another drive. Four miles...it started cutting in and out (again inc rev counter flicking on/ off)- I parked up, ten minutes later started fine and drove home. Is it an ECU thingy problem ?? If so where located/ how many of them/ where to get one ?.
LAST question - I `like` diesels, and would wish to convert the car. Which would be the best/ simplest diesel conversion ??

It's unlikely to be the ECU itself;take all the connectors you can find on the various looms apart,clean and a little vaseline on them.Then make sure they firmly click back together.

Most likely an ignition module fault. Check to make sure it has a good earth connection. Sometimes modules can fail when they get hot, and work again when they cool down.

Diesel conversion........interesting.......

Quite a bit of work there I should imagine, let us know how you get on.

Cavalier mk2 (convertible) - wanting to convert to diesel - which diesel engine is best suited ??

I could be wrong, but isn\'t the Isuzu unit the prefered one, as changing the clutch is a lot easier than on the Vauxhall lump?
In fact, did they ever fit the Vaux Diesel lump to the Cav, or was it just the Isuzu?

Yes but doesn't the Isuzu engine have a power steering pump or some other vital accessory plumbed into the alternator, making it a very expensive repair/replacement? Swings and roundabouts!

re clutch change - yes possibly but if I am doing an engine swap - I would change the clutch/ timing belt befor fitting the engine. (and would hope to not live long enought to need to do it again!) - what HP is the older diesel (1.6?) compared to the isuzu - any HP advantage ??

Hi again,
thanks for earlier advice -I will check out all connections again on the cavalier convertible 1986 SRi. I was considering a Diesel conversion -which diesel engine&box is mechanically better/ more suited to fit into the cavalier ? 1.6 or later 1.7 ? even the 1.7 TD? any particular year ?
