I had to take the engine back for the first time and after putting everything back i can hear the engine cranking but no fuel is arriving, i dont hear the pump. The throttle body does not open ( i dont know if thats normal) and all the other electrics work. I also notice when the key is on the second position the nats light stays bright red. Im out of ideas , i checked every connection and ground multiple times. Adding to that i cant see what gear the car is in on the dashboard (is auto)
