Morning,
I’m doing a reshell on a UK S14a and it will normally run for around 4 seconds and then switch itself off and then not start again once it had switched off.
Yesterday, after fitting a fuel pressure regulator and adjusting it to around 43psi we had it start for around 30 seconds but it then cut itself out again and then would not start.
It used to sound like it was running out of fuel so I topped up the tank, replaced all fuses with new ones, hardwired the fuel pump on a relay with a switch which works, checked all the original relays and had them tested at a local shop.
NATS has been snapped out of the ECU by Pro Tuner, the yellow engine check light used to flash but no longer does (no idea why this has just randomly stopped).
We’ve checked for spark, fuel, compression and it all seems fine.
Injectors are apparently Nismo 740cc from Garage SR (Don’t buy from him).
I had them flow tested from Nispro.
Wiring has all been checked, grounds have been checked.
Fresh fluids have been used all over.
Not sure what else I can do now!
