         Check the camshaft.  That'll tell you the firing order.  Rotate it 
in the normal direction until you're at TDC on cylinder 1.  Both lobes on 
#1 will be facing up.  Rotate it until the next pair of lobes are facing 
up.  That's the next cylinder to fire.  Repeat two more times and you'll 
have the firing order.
         As far as I know, 1-3-4-2 is the only firing order used for an 
inline-4 with a 180 degree crankshaft as it is the only firing order that 
results in primary balance.
