Default Ford Mondeo V6 won't start. - 04-09-2007 , 04:21 AM






The engine turns over easily enough but there it just won't fire.

I have checked all the engine management related fuses and relays as
best I can and they all seem fine.

The battery had just been recharged and refitted. I started it up and
it fired straight away, turned over maybe once then stopped. After
that it doesn't fire at all whilst turning over.

I have very little experience of modern car engines and don't really
know where to start fault finding. Anyone who can point me in the
right direction as to what to look for would be much appreciated.

Thanks

has it been standing for some time?

same as any petrol engine, check for fuel and spark. remove a plug, if it
is wet there is fuel or something getting through), refit it to the lead and
check for spark, if there are sparks, refit it, spray some carb clean or
easy start in the air intake, if that makes it start momentarily there is a
fuel problem, either gone off fuel, blocked filter, stuck pump etc.

You say it turns over easily enough, does it possibly turn over too easily,
ie faster than normal due to no compression? If so, suspect the cam belt.
I'm not familiar with your engine so I don't know how easy it is to check
what's turning or not. You may be able to see something moving by removing
the oil filler cap.

I am fairly sure it has a chain, so that is less likely

Yeah, according to a website I have just checked the V6 does indeed
have a timing chain.

I have checked for sparking and No 4 is definitely giving a spark, the
plug also smells of petrol, although it isn't actually damp so I am
guessing that I have fuel and spark in at least one cylinder. Battery
flat now so can't check the others.

Get a decent battery on it and give it a tow, that can often coax things to
life, you get a better spark since the starter isn't dragging a large
electrical load.

Freshly charged battery and a boost from my Xantia and away she goes
(eventually). Thanks for the help.

Was flooded from previous short run or much cranking.

All Fords have a Clear Flood facility whereby cranking with a wide open
throttle shuts off the injectors totally, so its always worthwhile giving a
non-starter 10-15seconds on the starter WOT just to make sure its not
flooded.

I never knew that. I'm quite impressed now.
