car keeps turning over and not starting so put new crank sensor on but still no joy is there anyway that numbers on coil pack are wrong ? we put leeds in order as follows from front nearest timing belt driver side 135 and passenger side 246

Correct. Are the leads correct on Dispack? Any codes stored.

Crank/no start.....Spark, fuel and compression needed. Double check ignition parts if you've tampered with coil pack 

[djhorner]

no codes stored when i put leeds in i went by numbers on coil pack can't remember them now , i have just heads done so if there is little oil where lifters are would that stop it starting ?

[omegod]

Can you hear the fuel pump prime when you turn the ignition on? not unknown for the relay or pump to go wonky, I think the purple fuel pump relay can be swapped with it's neighbour to aid diagnosis

[Webby the Bear]

Do you mean oil in spark plug wells?

[martin42]

Means oil in the cam followers 

[djhorner]

aye oil it hydraulic lifters there is fuel getting pump as we crack the fuel line off the turned engine over and fuel came out

[Webby the Bear]

lifters are meant to have oil in them 

[djhorner]

there is a little oil in lifters but if theres not enough would that stop it starting

Sorry, I see what you mean now.... you were talking about a lack of oil to the lifters  my mistake.

by cranking the engine unless im otherwise mistake will circulate the oil so oil should have reached there.

if fuel getting to engine--then has to be no spark--so coil pack or leads--

[djhorner]

new leeds new sparks and there is power to spark plugs will be checking all tomorrow

Lifters need full oil pressure to pump them up, just cranking doesn't generate enough pressure. When the engine first starts after a (re)build there should be mostly air in the lifters but this doesn't stop the engine starting (it does make a scary rattling noise until the lifters fill up though )

What may stop the engine from starting is having lifters that are already pumped up and are therefore holding valves open & killing the compression. This guide Cleaning and testing a hydraulic lifter describes the process of freeing up used lifters and preparing them for re-use.

so with that said a compression test would tell you if you had this problem, but i'm geussing spark, something not plugged in e.t.c
