[S13Gene]

Chassis: USDM 1998 240sx (kouki)

Engine set: ER34 Rb25det (Neo)

Mods: Cometic headgasket, Arp headstuds, Isis Intake manifold (r33 IACV not wired in) Aftermarket no name fuel rail, Aeromotive 13109 FPR, FMIC, Q45 Throttlebody

Pros: Starts with Brake kleen/ether, will idle, run an boost 12psi with no problems after started.

Things ive checked, CAS, injector and pulse also drivers (on ecu "battery voltage), Have Spark on all 6, fuel pressue (43 an holds ign on), Compression, IGN signal +, Timing

Plugs an gap..

Problem

Dont matter if it is hot or cold i have to spray it with ether to get it to start. Unplugging the TPS or MAF does not help, this problem appear to happen after going to the Aeromotive FPR as with the stock rail i modified to work it started every time. im using topfeed injectors double 11mm for upper an oem neo lowers oring on brand new r33 cushions (sidefeed) found 3 of the cushion to o ring leaking (spray with brake kleen an need a misfire) thats not the reason it no starts though.

The ecu has an input for cranking, so it knows when the starter motor is cranking the engine over so it adds more fuel.

I would be looking into that.

Alright, you have any idea what pin it is on the ecu? Should be battery voltage correct?

Anyone know were i can buy these? cant seem to find a solid lead on them.
