Rb20 won't start - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Hey guys, I've searched all over for an answer to my problems but SRs are apparently more popular than the RB20...

Here is the situation :

My fuel pump crapped out on me so I bought a Walbro 255 and installed it. The car worked perfectly fine and then the engine just died. It was fuel cutting every time I tried to rev it past 2k rpm. A couple of attempted start ups later, my fuel tank meter stopped working.

I thought it may be the fuel filter, so I replaced it. Same thing happened - the start up was great, and I could rev it however high I wanted. A few minutes later, it started to fuel cut again, and it died. Now the engine won't start.

It cranks, but no start. I heard a cluttering sound every time and couldn't hear my fuel pump so I tested it. The pump itself works (wtf).

No apparent leaks or cracks in my vacuum hoses - can anyone diagnose the problem?

Could it be my spark plugs? And if not, then what could it be?? Argh.
And... if they are my fuel lines - how am I supposed to replace them?...

Any information would be nice.

bad fpr maybe? are your spark plugs gapped correctly?

plugs are good. don't know about the fpr, and don't have the tools to measure the psi. :/
