Hi, i have a 91 integra gs, with a b18b1 swap. has a ls tranny, obd1 ecu, aem fuel rail, and adjustable cam gears. well my problems is basically it will start once in a while, it will always crank. if it sits for a while it will start but wont let me give it gas, it jus idles out as soon as it starts. maybe once or twice it started and stayed running then jus like stalled out once it warmed up. and wouldnt start back up.
any suggestions ?

please help thanks
