zetec timing issues, used kit but still seems out of time
I have a mk1 fiesta with an 1800 zetec. It was smoking so i had the head seals replaced. When putting the head back on i replaced the cambelt and of course had to re time the engine. With using to the kit to lock the cams with the bar when the crank stops at TDC again the pin in the block near the cps. However it wont fire now, I have a spark and fuel and when using break cleaner down the inlet it backfires out of the inlet which would suggest the timing is out.
Does anyone have any ideas i could try? As after checking the timing with the kit god knows how many times i don't know what else to do.
cheers

Too many posts.. I need a life!!
I had this once on a 2.0 zetec Mondeo I once owned.
It was the crank to cam timing that was out. I too used the pin in the back of the block along with the bar on the cams, thought, yep, proper job but nope.
This was ten plus years ago so the details are a bit vague but what I did in the end was to establish TDC via a (clean) 3/8's entension bar down Nr.1 plug hole and watched it rise and fall.
Logic says that you insert the crank pin then slowly turn the engine over until a crank web bears onto the pin. In reality I think that there may actually be a cutout on the crank web that the pin goes into or you put the timing out the other way and rotate the engine onto the pin from the other side. It was a Haynes I was using and we all know that they can be wrong!
I do remember thinking though that the timing was miles out and how did the car run after I'd supposidly timed it up properly.
In the end I did away with the crank pin and sort of guestimated it with the up and down extention bar on Nr1 plug hole and from memory of where it was when I thought it was miles out except it wasn't. It did run fine after that but really knocked my confidence as a DIY'er.
In short, check and check again TDC other than via the block timing pin. Either the way I was turning the crank onto the pin was from the wrong side or the pin screws into a notch on the crank web. I'll never know for sure as I fluked getting it running and running well again.
Someone must have had a similar experience and have better information.
