Engine Cuts Out After Heavy Rain

[Color_Of_Green]

Hi there

I recently experienced my engine cut out after driving for a while in the rain. When I got to work I checked for water under the bonnet - coil packs, inlet, connectors, etc but all was good & dry. Thought it would be ok if I left the car under cover during work but turned out my nice new nismo fuel pump stuffed its release valve and so had no fuel pressure.

I have had the release valve removed/blocked and a Sard fuel pressure reg installed. Its all been great the last couple of days except today again during heavy rain I was experiencing momentary engine cuts around 4000rpm and 30% load.

My PFC knock value does _not_ increase when this happens so I am gathering its not a fuel blockage / pressure drop issue. I am leaning towards an electrical fault somewhere... but how to trace? I mean, what else would have stuffed the release valve in the fuel pump like that? Or could a faulty fuel pump cause this type of thing?

Just wondering if anyone has experienced something similar or may understand what is happening?

Cheers

watch and MONITOR AIRFLOW or use SENSOR SW CHECK to look for any wacko values or out of range sensors (will go black highlight).

I suspect airflow meter is loosing signal or going out of scale, possibly water in the intake. do you have a pod? stock airbox?
