Hdi no start

[happypug]

Hi all, mine is a shit sunday so far. Come to use car this am, will not start. Would I be correct in assuming it`s the lift pump? I have had intermittent start probs for a while now i.e having to turn ignition on and off for lift pump to prime. The last few days there has been a loud noise coming from lift pump I presume? It will not fire at all, was ok yesterday. Anyone else with similar probs, your help please.
