Get a new hand pump -- if it leaks when you use it to prime, it sucks air in when the lift pump operates and you have air in the IP -- no start.

You will probably have to re-prime the IP, too when you get the new pump on.

I'd also check the compression -- did you re-set the valves properly?

It can take a while to get a dead engine running again, too. Took us three battery charges on my brother's 300D when we rebuilt the engine.
