No light is not flashing when cranking

Rules out the 1503 then. Have you removed the cambelt cover and checked timing as per Mark`s possible diagnosis :question

[Miggy24]

Hi hard to say.Sands like a rattling sound

[RobG]

I`d be inclined to whip the cambelt cover off, check the timing

[Miggy24]

Yes thats what im going to do 2moro.Can anyone tell me how to check the timing marks

[sneakypenguin]

this sounds like the exact same thing that happend to mine christmas eve. going down the motorway and came to some traffic so was doing about 10mph, all of a sudden the car cuts out, managed to roll it onto the hard shoulder the it just would not start.

Green flag came out and what do you know, starts first time. No warning lights on or anything. He got it running then after a few mins it cut out again and kept doing, so got it trailered back to my mums and left it till the 28th.
Now it seem when it has warmed up and ideling it will cut out, doesn't do it when started from cold (higher revs) and normal driving (again higher revs.

Starts first time and no strange noises, it's as smooth as it's ever been. I'm thinking ICV?

Do the paper clip test.

On a V6 expect failed crank sensor, on a 4 pot expect failed cam sensor.

If there is any chance at all that the cam belt tensioner is suspect then check the cam belt before trying to start it.

Hi guys iv had alook at the cambelt and it looks like it has slipped a tooth

[Andy H]

Oops.

I think people have mentioned that damage occurs if it is 3 or more teeth out  :-/

If you are one tooth out you may have had a lucky escape.

[Miggy24]

There is a metal plate with a needle on it and the plate says used new belt,does that needle have to bve lined up with everything cuz it alooks spot on with the marks so i must of did it wrong in the first place

[Andy H]

Not too sure with the twin cam 4 cylinder Vauxhalls (the last 4 cylinder I had was a carlton) but..

What condition is the water pump and the other idler(s) ?

Do any of the bearings feel rough?

[Miggy24]

looked at the cambelt again and found that that on the right hand side of the cambelt is loose and the other side is fine so it muct of slipped a tooth then when i lined it up it went bk on the right tooth

[Andy H]

Sounds like you are well on the way to finding the cause of the problem

Have you got a cam lock? I don't know if it is necessary to use one on the 4 cylinder (it is on a V6) when you take the belt off.

Before you get the belt off turn the engine (in the normal direction) until it is at TDC.

With the belt off I suspect you are either going to find that the spring tensioner has lost tension or that an idler or the water pump bearing has collapsed.

Have you turned the engine backwards at any point? that would tend to compress the tensioner and let the other side go slack

there is a new mark and old belt mark if you setup belt on old belt mark with a new belt mark the adjuster is nakerd and should of got the kit not just the belt, also depends on the in and out let on the two cams are in the right place if off can snap the tapates and warp the cam.

[Miggy24]

yeh i turned  it backward once alittle bit

[tunnie]

slap a new belt kit on there, replace the lot, tensioners, belt, water pump.

You need the locking wedge, you 'can' get away without, but for £5 its not worth the risk of using mole grips and having them slip off.

Its most likey one of the tensioners has failed
