    Default What have I done?

    Last weekend I cleaned the engine of my 'new' 97 model 1.8 litre DOHC 306. Afterwards I started it up and moved it to where it is now.
    On Monday I found it wouldn't start, so, suspecting water had got in, removed the coil pack to find water had indeed saturated two of the plugs and so blew everything out with compressed air. Put everything back together but still no start.
    Today I removed the plugs (2 were only hand tight), sprayed all contacts with contact cleaner, including coil pack connection and injector connectors, but still no start.
    Given that the computer is is almost impossible to get wet (for good reason) I don't think that'll be the problem.
    Can the coil pack have a flaw to cause no firing just for one cylinder?
    What else should I look at?
    The car was running fine before I mucked things up, and always started up immediately as 306s usually do.

    Does the tacho needle move when you crank?

    NEXT time, drive it around and get things really hot and dry before shutting down. Sorry not to be more direct help....

    Personally, I never feel the engine area needs that sort of a clean. Easy to be wise though.

    Best wishes for the startup.

    Crank sensor is below that area could be wet can be a bugger once water gets in just pull of plugs and dry till it starts especially the spark plugs could be wet in there Fish Doubt if its the. Coil pack itself

    Sit the coil pack on top, ground the metal fixing eyes, look for sparks as you crank.

    I'd suggest trying some "Démarrer, Salaud" (ether spray) first, though. If it kicks you have a fuel supply problem like the tachymetric relay not pulling in.

    I washed the wife's 406 engine and the car got used almost straight away, and no problems.
    Trouble is the 306 isn't registered so I couldn't drive it around. Should have left it running longer though.
    Will have a go tomorrow if feeling well enough. Plugs and plug wells are definitely dry.

    Yes the tachometer needle jerks when operating the starter.

    I'll have to look for the crank angle sensor (no idea where it is) and have a look at that. In the meantime I'm going through the various connectors and spraying them with contact cleaner.
    The silly thing is that the washing really didn't produce much in the way of tangible results. I should have used a big vacuum cleaner to get the leaves and sticks out of the wells on front of the windscreen. I wish people wouldn't park their cars under trees. Mind you this poor car has probably never been parked in a garage in it's life given the state of the upper paintwork. Being black it means that the Melbourne summer sun has done its worst over the years, and I'll bet it's been a hot box on hot days.

    There could be water in the Plug for the fuel pump / ecu relay, on the back of the battery box. I had that with my Mi16 but where that's located I had no idea it had one! Took me about 2 days to find and in that time definitely didn't dry out itself.

    OK, the tacho flicking means almost certainly the crank sensor is working fine. So you should have spark.

    Try the ether spray, I suspect it will be a fuel pump switching issue.
