Hi Guys,

I tried to start my 924 earlier today and it was just firing up and dying again.

It seemed that there was pressure in the fuel line to the
fuel distributor, but didn't seem to be fuel coming out of the fuel distributor (checked by loosening off the fuel lines from the distributor to injectors).

After checking a few other things we got it going but then it wasn't running on all cylinders until my Dad loosened one of the injectors and then it started running o.k.

I'm just concerned that this could be a sign I have got a problem with the injection system.

Is this a common problem and are there any other things I should look out for.

Thanks

Kirk

you wont get fuel unitl the fuel distrubutor presure plate is lifted, and the fuel pump is running, the fuel pump wont be running unless the engine is turning over, even with the ignition on.

it could be air getting in from the injector seals, but in my opinion, I would say it more likely that your dad moved the spark plug wire that was shorting to earth somewhere.

next time it starts missing on a cylinder, listen carefully around the plug wires, you might here a ticking/sparking noise...

just a hunch.

when you get dirt,water,muck, anything down the spark plug holes, especially between the cap that goes on the end of the spark plug, and the engine, then it will give you start problems and misfires, which miraculously disappear when all the pipes and connection have been checked in the engine bay. OR when the damp drys out of the dirt after the engine is warm.

Hi,

Thanks for the reply.

There was a ticking noise from around the spark plugs so it may have been that.

It's been o.k. since, so I'll have to see how it goes.

I would change the plugs & wires.

I've found that if a spark plug is breaking down, it will cause the leads to short.

The energy of the coil finds an easier path to discharge through the lead to your block, than across the plug gap itself.

This vehicle is a bitch for getting crap down into you motor, when you change the plugs !!!!!

First pour a small amount of engine degreasant/cleaner down the plug holes BEFORE YOU LOOSEN OR REMOVE THE PLUGS.

Let it settle over night, then clean away with an airhose BEFORE YOU REMOVE THE PLUG.

This way your less likely to get all the crud thats sitting around the plug in the motor.

It will come back to haunt you, on damp days, when the motor has been left outside all night.........it wont go away
