Re: hard to start
Odds are it's the anti-drainback valve is leaking fuel down from the
injector rail. The anti-drainback valve's function is to allow flow
into the fuel-injector fuel rail but not back out of the rail. If the
fuel rail has has its gas drain out, it takes a few seconds for the fuel
pump to get fuel back to the distributors.

On my '93 XJ that was easy to test... take off the
bleeder port cap, and depress the Schrader valve
with a small sharp instrument... have a rag handy,
and wear eye protection! You should get a spurt
of gasoline under pressure if your system is working
well.
The safest way to do this would be with a
fuel-pressure bleeder-gauge rig... pretty
cheap, and indispensable when troubleshooting
FI problems. Mine cost about $40... bonus,
you can fill your mower without sucking on
a tube!

Re: hard to start
It's hell when we feel we must warn people what pressured gasoline
may do.
That extra R-12 gauge and fittings should be perfect to read the
forty pounds, ninety pinched return line.
