Engine wont start,

i was driving along 30ish in a 40mph, engine went to die(revs droped) then got to say 5rpm and picked back up to normal ish tick over at 30, then 20 yards down the road revs droped but never pickewd bk up so, i droped a gear revs picked up then died so i cruised to a hault, had a quick luck but was getting on and was very dark so pushed it up the road to a safe place ect, its an ecosse car so they had removed the toe'in eye, so left it over nite, come back in morning to get her home, and got it home , but still wouldnt start, it sounds like it wants to start but no spark in the engine so my 1st guesses were coilpack, spark plugs or cam belt???i have changed coilpack with 1 i had lyin about, i changed spark plugs 2weeks ago(as well as oil filter and oil) they look fine, and cam belt is fine, any idears???im lost HELP!!!!!!!!!

prime it with the fuel rail/ injectors out. if your eyes are burning then chances are its sprayed out all over your face, into your eyes, and you cant see. chances are after your eye sight returns you will realise you have good pressure!

Rule things out before replacing fuel rails etc.

1.Have you definately got a good spark on all four spark plugs?
2. Have you got fuel delivered to the fuel rail? - if so at what pressure? - you need a guage.
3. Before replacing the crank sensor get the dtc's read on a diagnostic machine - if there are any! If there are record them and clear them and then try and start it again, this rules out going off old codes if any are stored in the ecu memory.
4. Have you checked fuses? If not..Why not?
5. It is possible of a cambelt failure, take off the top cover and turn the engine over by hand and look at the belt- if unsure put a line on it with pen and check the belt when its come all the way round.
Hope this helps
