had a 2.0 16v xe and broke it so ive put another in. Everything was ace, had it running but then i swapped the cambelt and now it wont start.
so far ive changed plugs, leads, dizzy + rotor, cambelt and tensioners. Also done a compression test and everything was fine. Swapped airflow meter and icv from old engine and made no difference.
The only thing im not sure about is this little box on the right hand side of the inlet manifold, about the size of a matchbox its got 2 rubber tubes coming off similar to those under the throttle butterfly. Its not actully connected to the manifold, just mounted there, i have no idea where this is supposed to be connected to.
Help please

if it was running before you did the cambelt but not after, then i'd say it would be a fair guess to say there's something not right there.
i'd re-fit the belt, just in case.

im gonna do that tomorrow, fairly confident its perfect tho.
Cheers lee 
i suspect it to be electrical problem, couple of plugs and wires i couldnt remember where they came from . One to the icv and one just underneath into the block were very similar, swapped em round but it didnt make a difference

if you have a spark and fuel and you have just changed cam belt youve got it a tooth or two out. time it up and see if they line up properly

the only thing shinnee said that could be wrong if it was running and now not after a cambelt would be that the timing is out 180 degrees on the bottom pulley. the icv and knock sesor are the same but one has a red plug the other black. im 99% sude the red is to the knock and the black to the icv

really confused now
how can i turn it 180 deg? The marks wont line up properly then. Im fairly sure its right, No 1 piston is at the top.

the crank pulley turns twice to every 1 turn of the cam pulleys
or so i think......

yea thats right. the cams will be lined up but the bottom pulley can be one whole turn out so in theory the bottom pulley is 360 degrees out but the timimg is 180 out if u know what i mean. to be honest its hard to do if u just cut the old belt off when its all lined up and just slip the new one on. but if the marks wernt on and u cut the belt then pu tmarks on after its easily done

so either way number 1 piston is gonna be at the top. my dads been messing with it so fuck knows where its up to
so if i say its wrong now, take tthe belt off and rotate the bottom pulley 360 deg in theory it should be right?

One revolution of the crank = the piston no1 going from tdc to the bdc back to tdc, so no if you turn it 360 it wont make a difference, the difference is you time the crank in wrong with the cams i belve, the crank sprocket is smaller than the cam sprokets so the crank will be turning quicker than the cams, so if the cams turn once the crank turns twice if thats the correct ration so its timed wrong i bet, i have now confused my self in what im saying someone put me right of correct me lol,

if i just turn the bottom pulley once then its gonna do a full rotation and not change anything

no i think its one rotation of bottom pulley is just one up or down stroke of the piston. so if ur timing marks are on with plug number one out. the piston should be at the top. but i think urs will be down the bottom if u look

only way to check is stick a long thing down spark plug one when timing marks are lined up and check piston is at top not bottom

if the bottom pulley is out 180 degrees piston 2+3 will be at the top instead of 1+4

this is why it says in the haynes when you change a timing belt to rotate the crank through 2 full revolutions therefore turning the engine over once.
jesus fo once i'm right about something
erm.. what i'd do is line the marks up with your spanner whip off the belt...
keep the cam pulleys were they are and rotate the crank 1 full turn.
stick back on the belt tighten it all up then roate the crank pulley 4 or 6 times and make sure all the marks line up again.
then try starting her.....
