Car cranks but will not fire up

[Alex170984]

Right its all together.

My mate did the cam setting and everything for me at the weekend and the electrical / water pump issues i had previously have been dealt with.

After charging the battery for a long time, it cranks for longer but will just not fire up.

There is fuel in the rail, you can even see it on the end of the spark plugs as well, but no power. It sounds like its tries to but just won't do it.

There is also a strange sounding puff coming from the inlet manifold when it cranks over.

Any suggestions?

16v rebuild by the way with new pistons, rings, head gasket & cams.
