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.
