what about fitting an apexi s-afc? and removing the regulator. :?

just a thought mate

make sure your AFM isn't maxing out, or your injector duty cycle. Both can be maxed out at 1 bar...

they are pretty sure it was fuel pressure,,
have ordered a new wallbro, and regulator

with the safc i thought i still needed a regulator ???????

YEH OR NO

also once new wallbro is in, if i fitted a safc, what else would i need to solve problem if it is fuel pressure, etc

Did they check the voltage at the fuel pump? It may have a manky earth.

 

[nismoboy]

as fast guy say check your fuel pump voltage as i have this problem i only have 12v at the pump! and walbro`s need at least 13.5v to work fully.

I had to search for this cos my car was sputtering at high revs the other day, after checking it out with a voltmeter i was only getting 11.5 volts at the pump :?
