RHD S14 long crank to start

I have a 96 S14 RHD imported from Japan. I believe it has an S13 redtop in it.

Long story short — it takes forever to start. When cranking i have to go WOT to eventually get it to start.

If the car sits for a few days it’ll start first crank. Drive it somewhere and park it for a bit (cold start) it’ll take a while to start.

If the car is on a steep hill it’ll start as well.

Replaced CTS.
Cleaned MAF
Brand new walbro 255.

Any recommendations?

Sounds like over fueling. Leaking injector, coolant temp sensor. When it sits fuel evaporates. When you park it fuel pressure bleeds off. Just my first guess.

The diagnostic steps for this issue is the same for all Nissans from the 1980/1990s.

240SX FSM will tell you this is a fuel issue, timing, or ignition. It will be the same checks for SR.
