I recently tipped my 2004 impala on its side it is a 3.8 ss and now it won't start. It turns over fine but will not fire what could be wrong with it
Fuel cutoff switch was tripped.
There is no inertia switch on a 2004 impala.
Doh! Your right, the OP might want to check for spark and fuel pressure, since it cranks. Thanks for correcting me 707.
