I got into a slight accident the airbag went off. The car cranks but there is no gas going into the engine and the fuel pump won't activate on its own. But when we tested the fuel pump out of the car, it works.

We looked through a manual and found a saftey relay in the trunk area and we replaced with one from the junkyard hoping it would fix our problem, but it didn't.
After an accident is there anything computer related that has to be reset because the airbag went off?
Does the car automatically not start after the airbag goes off, if so then what do we have to do to fix that?

I would appreciate your help, thanks.

By the way the car is a 1993 Maxima SE

 

Was the junkyard part working?

 

We thought if we just replaced it that it would fix our problem but we didn't know a way of telling if the saftey relay actually worked.

 

Woah, this is strange. Maybe call up a dealer or shop and ask them?

Safety relay? where?
