Mrs.NCoT's Puma won't start.

She came to drive it after it having been sat for an hour or so, backed it out of the drive, pulled away and thought she stalled it. Wouldn't restart, which is normal as they all apparently have hot start problems.

However it wouldn't even fire with some throttle, and eventually stank of petrol.

I came home and tried it a few hours later. Starter runs but not even a cough from the engine.

The fact that it just conked out is making me suspect a sensor of some kind - crankshaft/camshaft sort of thing...

Any ideas? How easy is it to pull codes on these things?

If it is fuelling ok, that sounds like the fuel pump and injectors are running ok. I _think_ the immobiliser would stop that happening. Crank sensor is certainly a possible candidate, as are the connections to the coil pack, and the coil pack itself. If you have any test equipment, test to see if the coil pack is actually getting any signal from the ECU.

Just had a thought. It seems to be spinning over quite quickly. If the cambelt had snapped and there was no compression it would have the same symptoms... eek

Call to the AA tomorrow. Can't be doing with these newfangled modern cars.

I think if the cam belt had snapped, it wouldn't be pumping air+petrol through the system. Fingers crossed for ya...

Update:

No fault codes on the dash diagnostics

When trying to start the engine none of the accessory belts turn, which suggests starter not engaging properly to me.

But: Just tried to move it on the starter thinking it wouldn't move as it's not engaging, but it jumped forwards banghead

On the phone to the AA, I'm out of ideas and it's started raining.

Depends on the garage and the reason its actually failed. If its done 12k then it must have been fitted correctly or it would not have lasted. Did it have a kit inc the tensioner or just the belt??
If it is a genuine belt failure (which tbh is rare) then you may have some comeback against the belt manufacturer but the belt (or whats left of it) will have to be sent away for inspection first.

I suspect when it was done the tensioner wasn't replaced, and that's what's failed.

Many bent valves I'm afraid. Might be easier to try and find a complete engine from a breakers.

In contract law any comeback would be against whoever sold the customer the belt i.e. the garage that fitted it. The belt manufacturer might choose to back that up for the sake of their reputation but any claim would be against the seller in the first instance.

Calling Tremona (Ford/Puma specialist) tomorrow and asking their advice. If they can fix all well and good, if not then hopefully they can supply and fit a decent s/h engine.

Depending on where you are and what you can do yourself I might be able to suggest who to go to. A colleague can sort the head out if you can take it off and post it. He might be able to do it all if you can trailer the car to Sussex. Inlet and exhaust valves are on Ebay for only about a fiver each but I have no idea of the quality. You might check Ford prices though just in case OE ones are not too dear but often you get a real shock. AE or TRW might also list them by now.

I suspect the crankshaft pulley bolt has become loose, (there is no woodruff key on crank/pulley).
The valves will be bent.

Tremona have confirmed that the valves WILL be bent frown They are rammed at the moment so can't even get it booked in until Jan. Bummer.

A warning to all, don't skimp on just doing the belt alone!

I almost always do the tensioners as well as the belt (the only one I haven't done the kit on was a Renault V6, but never heard of a problem with this particular engine) because it is false economy as you have found NCoT. However, if you are not of a mechanical bent then you wouldn't know.

My friend with the Vectra (I got it from a neighbour.......) managed to drive his car 40 miles one day and heard a helluva noise coming from the engine so he stopped.

He described it to me and I diagnosed the timing belt, likely a tensioner.

I went and towed it home, took it apart and sure as shyte found the top tensioner hanging by the last thread yikes

How the hell that engine didn't just let go at that point was a helluva surprise!

Anyway, I put it together with a kit from the dealer and away it went.

Still going too cool

Unfortunately was done prior to our ownership and the receipt says "timing belt kit". All I can assume is the tensioner was not included in the kit. How on earth I was supposed to know that I don't know. What else can you do but check the service history?

Kit normally implies tensioner too. Just a belt would be no more than £15 to £20. A kit would be more than twice that. I'm sure you can find out if a tensioner was included from either the price or checking back with the supplier from their invoice number.

NCoT, please don't think I was implying that you were silly!

I guess if it says "kit" on the receipt then that what you would assume!

However, I have heard of tensioners letting go before they should. Depends on the quality of the kit.

If it's any help, it's as Puma Racing says, the belt is around £15 and tensioner kits can be anywhere from double that to serious money.

The Renault V6 belt cost me £74. The kit was going to cost £400 eek
