2000 Sienna - Race van will not start - Need help !!!!!

What is your question?

Bought Toyota Sienna brand new in 2000. Ran great until I cut wires out of rear of van getting ready for a local race. Still turns over but will not start. Getting fuel, but no spark at plugs. Possibly related to security system. Desperate, put to much time and effort getting ready for this race. Any help is appreciated.
