I just put plugs and wires in a Towmotor forklift, and now i can't get it to start up. Help?

Firing orderis 1-3-4-2 and #1 is in the front at the fan end. This is from a book for V80-V100E. Since this is the only thig you have done and now it wot run it sounds like you got the firing order messed up easy fix.
