The pump has a max flow rate and usually will not exceed it...bad/low/no pressure will cause a hard second/warm start. If so, it is most likely the accumulator or could be the check valve leaking. Cold start is usually indicated by other symptoms.

Look inside the right rear in-fender panel at the accumulator, if it has a gas smell and you can see seepage on it, it's leaking gas and pressure. Look (under the pump panel) at the check valve, either within the pump or external for any leaking/seepage.
