Not really bearing in mind in your other thread you've probably cranked the hell out of the battery trying to get it started.
No fuel AND no spark is almost always something electrical that's gone wrong and 1st thing you should always check is the battery.

Andrew,I have been fully recharging it every time i have tested it,and allways start with a full charge,i dont think a flat battery would acount for no fuel,when i remove the plugs after cranking (with the fuel pump fuse in)they are dry as a bone.thanks for your interest.

no fuel and no spark
could be a faulty flywheel pick up sensor,this should log a code though,worth checking with a code reader.

Could still be the cam belt.

Cam belt only 3,000miles old and i would have thought loss of cam belt position would have caused some sort of clatter,dont think it would account for lack of fuel or spark.thanks for your comments though.
Ps i am now leaning towards an alarm/imobilizer problem.

the flywheel pick up sensor takes a reading of the (flywheel) so even if the cambelt had snapped you would still get a spark/fuel pressure as the starter turns the flywheel when cranking,if the camshaft can't be seen through the oil filller cap its worth removing the top part of the timing cover to have a look a the belt.
