for f**k sake valver problem!!!

[couzens]

was giving it some and then there was a massive bang and the car died engine will turn but wont start help

 

[Budgie]

Ouch. You don't have much luck, mate.

It just won't fire?

Does the engine turn at normal speed or faster?

 

[couzens]

sounds normal to me mate? dont know what it could be :S but yeah just wont fire

 

[sideways danny]

massive bang sounds like cambelt failure tbh, but the engine would normally crank faster due to loss of compression

 

[Budgie]

That's what I was thinking.

Can you see the cams if you take the oil cap off on the Valver lump? I've never looked one over before..

If so, get someone to turn the car over. Watch and see if the cams turn.

 

[sideways danny]

you can just about see the cams yeah, the filler does have a baffle half covering the opening under it though

 

[couzens]

cambelt was only just done! :S or so ive been told, have a recipt tho! ffs this day just gets worse and worse

 

[Budgie]

It's worth checking.

If it's only done recently, it'll be covered by warranty

 

[wilky19]

if you can't see the cams down the oil filler take the distributor cap off and see if the arm is rotating on cranking

 

[couzens]

It's worth checking.

If it's only done recently, it'll be covered by warranty

it was done by a friend of the previous owner?

 

[R-Sport.]

no warranty then- lets hope its not worst case scenario

I had the same problem but it turned out to be the fuel pump. I think where mine ran out of fuel, it cut out so violently because I was in the middle of changing gear.

Can you hear the fuel pump priming when you turn on the ignition?

 

[couzens]

its got just under quater tank, i havent had a chance to look into it, just came home from a funeral and i had to ditch the car in a lay by, going to get it in a min

 

[couzens]

right, cambelt is intact, cams are moving, looks like no spark going to engine, the massive bang was like it was backfiring, not something exploding

 

[Struggler]

no fluids coming out??

check the spark and compression,
can you smell unburnt feul coming out the exhaust?

 

[wilky19]

what's happening on the dash when its turning over

 

[couzens]

dash is normal as if i was to start the car normaly, ive got a decat and it pops and bangs so theres always been some unburnt fuel im completly stumped tbh!

 

[Struggler]

pop/bang could have been coincidental?!

distribution block might have gone? (or have you checked sparks??)
how do you know the cambelt is intact??
could have lost a tensioner and caused the engine to fall out of line,
but that would make it crank slightly faster

 

[couzens]

tension seemed fine on the belt? the cams looked to be turning normal speed, we couldnt get a spark so i think it could be the dizzy but i replaced that about a month ago lol

 

[sideways danny]

ok, if the belt hasn't had something happen, then a backfire is normally a very misplaced spark. Check everything is ok with the dizzy, maybe the rotor arm has broken or the cap has come loose and damaged a contact?

 

[couzens]

cap looks alright to me, i havnt taken it off to see the rotor arm atal, i cant remember what the things called that sends the power over to the dizzy via a lead, lol metal block ftl, could that have something to do with it?

 

[Whiteley]

Sounds like what mine did, 9.35 onwards in this video:



Turned out to be Crank/TDC sensor. Cleaned it and I was away again.

 

[couzens]

doesnt sound like your engine cut out tho? mine just cut out asif it had stalled

 

[Whiteley]

It did yeah, right at the end of the video, had to be towed back into the pits!!

Worth a try though. Battery and airbox out.

 

[couzens]

and it wouldnt start like mine?? im a n00b when it comes to engines lol where abouts is the sensor? i replaced a clutch on the car yesterday and bat and airbox was out, so people have been fidling about in that region

 

[Whiteley]

Nope, wouldn't start as you say. Turned over and turned over until we cleaned the crank sensor. It's bolted to the top of the gearbox, right by where it meets the engine. Couple of 10mm bolts iirc.

Quite probable if the box has been off too.

 

[couzens]

fingers crossed its that then!

 

[wilky19]

should be able to test if it is that. when you crank it is the revs bouncing, if not its defo the crank sensor

 

[couzens]

all fixed! was the crank sensor, cheers whiteley
