New motor is having problems

[listed]

I finally put the other motor in my svx and it started right up only to die about 10 seconds later. this became a continuing problem. the check engine light never came on, it seems as if it is suffering from a loss of fuel (the pump works). I'm about to go check the codes but since the check engine light never came on I don't think I'll find anything. Next step would be to swap airflow sensors. My guess would be a sensor on the motor since it has been sitting for 2 years, but I don't know which one.

Thanks,
Chris
