Went to get Sunday papers and my 2003 2.6 will not start, have not had any problems before (other than crank sensor)
It tried to fire once and now the starter is turning the engine over but too fast. It is as if there is no compression, have checked the timing belt and it is turning round OK, can see the camshaft moving in the oil filler hole also.
I replaced the belt and tensioner and water pump (all genuine) 42,000 miles ago. Car has got 134,000 miles on it, uses a little oil (1ltr every 4000 miles), uses no water.
Any thoughts before I end up elbow deep in oil/grease...

now overdue another change.
you really need to check the timing aswell tbh.
-
Have you checked for codes?
Given your description I would be taking the cam belt cover off and checking that it hasn't skipped a couple of teeth (that would be enough to lose the compression but not do any damage to the valves). You can check that using the marks on the metal cam belt cover.
The Omega does turn over pretty quickly even with good compression so it could be the crank sensor (again)
The V6 doesn't use the water pump to tension the cambelt. It only becomes a problem if it fails so catastrophically that the auxiliary belt takes the cam belt cover off
-
Just got it in bits all over the drive, the belt is still whole and the marks are lining up OK.
Aux belt tensioner bearing has a bit of play (will change if i get it running)
Should have plugged the laptop in before I got the spanners out.... trust me to think the worst (must be cause im a scorpio)

Showing code 1 7 10 10 .
P1700 Service Vehicle Soon Request from Transmission Control Module
Changed transmission oil and filter 10,000 miles ago. How can i reset ?

Selector Switch?
I still think crank sensor

Flooded, happens all the time.
Cold start - short run -turn off - no restart.
Try cranking and crancking for what seem a rediculass amount of time with the throttle full down, after 30-45 secs lift off the throttle gently and it should start.
If that doesnt work, plugs oil, blast of air and a small drop of oil in each bore, and all will be well again.

Nah, not on fuel injection cars.
And if a car does flood, thats tells you there is an issue with something

I'd be more likely to check for NO fuel at the injector rail, not too much...

Flooding is VERY common on FI cars!
They're worse than carbs for it!
I see them all the time(recovery driver), and it's inevitably down to not running long enough for the cold start to cut out. I find if the battery is up to it to crank it over with the throttle open and see if it starts. Otherwise pulling the pump fuse(or tripping the pump cutoff) and then cranking it over is the way to go.
Some cars are worse for this though; Zetec engines are particularly bad, and RX8 are a nightmare.
-
Happens alot on FI cars,
especially autos.
Jaguar V8 were really know for it arround 1998-2001 model year.
My mums 2.6 omega and my 3.0 have both done it 3 or 4 times.
Seriously I never imagined there would be so many doubters out there.
Have we heard if my tip worked or not yet.

my 3.0 24v senator used to flood on a regular basis pull fuel pump fuse spin over till it fired reinsert fuse job done sorry mark

Stuck boost pack on it and kept turning the engine over, eventually it fired on 1 then 2 then 3 until it went on all cylinders.
Never ever came across that on a FI car before...........
Thanks to all, still got transmission error, but can live with that

That's all the classic symptoms, and the way it starts! it's a pity that pulling the plugs is such a pain in the arse on a V6, as that's often what it takes. BMW 6 cylinders invariably need the dried off by hand to get going again.
-
I've had this sort of thing on ours, though I don't remember it turning over any faster than usual.
I'm amazed the starter motor didn't burn out during the many long foot-to-the-floor 'come-on-you-b****rd, start!' sessions during test drives before I discovered that a wire-to-wire short had killed the coolant temperature sensor and was making the ECU believe that the engine was at -45.
I'd dare to suggest that this type of fault is one of a very few things that could cause this behaviour on a FI engine...
-
my uncle has a volvo 960 24v and if he starts the car and reverses out of the garage then switches off then it will have to be left for several hours before it will even think about starting :-X
-
You dont need a fault temp sensor to have this happen, but yes if the car is fueling for -45 that definatly isnt going to help.
Because they have sendary air, they are not just fueling loads for a cold start, they are also fueling extra to keep burning the exhaust gas to heat up the cat while the secondary air pump is running, that is lot of fuel.
If you switch off before the end of this cold start period of extra fuel injection especially if you have just moved the car, say off a drive or out of a gargage you can get this. It spins over really fast and sounds like a broken cam belt because the oil is washed off the bores by the fuel and engine is genuinly low on compression, thankfully only tempory.
