I have a 91 crx it sat up since may and I just put a d15b vtec in this past weekend. I sat the engine in and hooked up all appropriate connectors with the exception of two wires that is close to the intake manifold (yellow w/ green and a black) I have no clue where they go all i know is if you connect the wires together the main relay closes. But when I go to start the car you can hear the fuel pump kick in, the cel comes on for approx 2 sec then secures. The engine turns over and attempts to start and will fire for about 3-5 sec then stops firing and back to turning over. I replaced the spark plugs/wires, checked dist, replaced the map sensor and idle control valve. Im stumped can someone help

5.4volts
the check engine light come on and then off after 2-3 seconds
you can hear the main relay click
you can hear the fuel pump prime
The two wires were for the thermostat sensor
