WTS Light? - do you get it when you first roll-on the key?
Tach Movement? - does the tach needle move up slightly when cranking? (some '01s aren't supposed to though, do you have a digital odometer?)
Fuel - pump runs? Tank below 1/4? Is there fuel in the fuel bowl now? Does it refill after cranking? (open the drain level to check)
Is it cranking fast enough? - it won't even TRY to start if cranking really slowly.
Has the "Check Engine" been coming on at all? - codes would be the fastest way to direct you. Unfortunately, it takes a special scanner to retrieve them...
