hi hope someone can help . my old girl has started to play me up its a carlton 1800 .
starting up when she feels like it and then cuts out , when she does decide to run its a low powerd effort from her .no load she ticks over nice (sometimes).took air filter off and was easier to start but the carb spat out and sometimes smokes up , but when she wont start i take out plugs and there wet there is a great spark at each plug.
what i have done is changed the rotor arm new (made sure this went on right way)
distributer cap new
leads new
oil and filter change
erm im pulling my hair out this is the first time she has let me down in anyway in 6years from what i can tell the carburator is a piperburg (think thats how its spelt)
all help is desperatly need as my wifes doin her nut at me .

From your description, I'll assume you have a MK 3 Carlton, with the distributor cap at the back of the engine.
If you are pulling the plugs out after an attempted start, and they are wet with fuel, then the carburettor is probably working OK - leave that alone for now.
Check that the cam belt is OK *and* that the cam timing is OK. (This is only a 5 minute job, because you can get the upper cam belt cover off these in no time)
Then, without moving the engine, make sure the rotor arm is pointing to number one segment in the distributor cap, and that the remaining plug leads are in their correct order.
Remove a plug lead from the cap, and check that it has the correct fitting - there will be either a pin, or a cup in the cap, and the plug lead will end in a thin tube to grip the pin, or a wide expanding cylinder to grip the cup respectively.
On some crossover cars, you can have one type of cap, and an incompatible coil terminal (the changeover of distributor caps and coils was mistimed at production). If you have this scenario, there is a special Vauxhall coil king lead which has the appropriate fitting on each end.
Next, have a look at the coil, and it's associated power electronics stage - you need to ensure a good earth connection for the power electronics to run properly.
I can't remember off the top of my head whether this is EZ-plus, or EZ-61 ignition, but, there's a good possibility that you can read fault codes from it - follow the instructions for getting codes out as given here;
www.topbuzz.co.uk/info/fault_codes/fault_codes.htm
Although the codes you might get out won't match any listed here, please report back with what you find. If there are no faults logged, you will just get code 12 - i.e. one blink.......pause......two blinks.......pause.....one blink.......pause......two blinks....... until you switch off.

I think it may be best if you ignore the bit about fault codes - IIRC, the Carlton had EZ 61, from which you can't get fault codes, while the Cavaliers had EZ plus, from which you can get fault codes.
Having said that, it isn't a hugely complex system - the wiring diagram in a Haynes manual and a multimeter is all you need for most checking.

Was the problem there before you changed the parts ? or did you change the parts hoping to cure the problem?
let us know because of next step advice.

the problem was there b4 however i have took the carb off and had it all cleaned jets and what ever else they did .it started gr8 but problem reocured .however the wife has noticed that there is a ticking that can be heard from inside the car it sounds like a relay .
the engine has got its dizzy cap at the rear of he engine by the bulk head.as im not very sure about engines and as some 1 has already said number 1lead with something im lost ther my friend ,but it is something to learn . its misfireing at load and tick over is none i have to keep foot on acelerator to keep her running .thank you all any more suggestions bombs not an option at the mo...

hi me again
i have had the timming checked with the number 1 plug with top dead centre and its bang on .
all spark plugs give out a strong blue flash .
the misfire is still there it is as if its a intermitant spark .
i have been told that there is a little black box just behind the coil and if this breaks down this can cause this .i hope that this is right before i order a new part as this has nearly hit the 4oo quid mark what with paying for carb to be cleaned and to have the timming checked and its full service .etc etc.
any more ideas for me to try that are fee or cheep as my pockets are not that deep and i am now getting desperate.
thank you every one who has helpped antuk

the little black box is the trigger stage I mentioned above - make sure it has a clean earth, and don't buy one unless you *know* that your one is faulty.

is there a way the trigger stage can be tested , i have removed it from the car and cleaned it up as much as i can.all the terminals look clean and clear .
|
>>i have took the carb off and had it all cleaned jets and what ever else they did .it started gr8 but problem reocured
What else was done, and how long did the fix last?
Checking the final stage by the coil isn't straight forward without any test gear, but, if *all* the connections to it (especially the earth) are OK then you have done the cheap and easy bits.

ok jobs that have been done.
new plugs
new leads
new rotorarm
new dizzy cap
new air filter
new oli and filter
carburotor removed and was stripped cleaned and rebuilt.
timming checked .
as i have already said in my previous message when i had the carb cleaned it did seem to cure it but for only a short time ie 4/ 5 mins.
also my wife has noticed a ticking sound from inside the car a relay is there a relay for the fuel system ??
my daughter has told me just that my petrol cover was open the other day and shut it for me as there is no locking petrol cover could it be possible that some water or something been put in there .and if so would this cause this kind of problem ?
thank you all help greatfull .
