s13 dies when ignition switch buzz comes - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Car is a 90 s13 ka24de swapped. This started to happen after I removed the scv from the intake manifold. What happens is when I crank the engine over it starts and runs ok for about 3 seconds then a buzz from the ignition switch comes on and the engines dies out. Also for some reason when I put the intake mani back on, I found two grounds coming from the injector part of the harness that happens not be shown in any of the diagrams I can find online. The CEL also doesnt flash when it indicates its priming.
list of stuff of how I have the hoses ran:
vacuum hose fed from back of manifold to fpr
throttle body vacuum line capped off
hose from iac goes directly to intake tube, pcv from valve cover has a filter on it
there is a plate where the scv used to be
no other emissions equipment on car
another thing is when I try to floor the car too keep it running it does not rev up, it just hesitates and dies. maf sensor seems to work fine on a friends coupe. I also swapped over his blue egi relays and same thing. It runs a little longer with the maf unplugged but it still dies after about 10 or15 secs

did you connect those grounds back on? check for fuel spark and airflow...if any are hindered it could cause this...

connected both grounds on intake mani, its getting fuel and spark. I'm starting to be almost sure its a vacuum leak because I didnt plug up the scv rod holes when I removed them. they are probably causing a massive vacuum leak. I saw the offbeat garage emissions delete guide on youtube and he didnt fill his scv holes with anything.

fixed. It was low on gas and the fuel filter was clogged. Thanks yall.
