It Died in its sleep...Help

Most of my repairs in the past have been to older model Chevy trucks where parts are parts and Jeep where parts are parts of other things so Yoda are rather new to me.
VEhichle is
1995 Tacoma 4x4
Standard Transmision
3Rz-n or 2.7 with coil in dist. cap

park it in the enevning it was running great
Next morning it turns but no start
Last time this happened was just after I baught the truck and I called previous owner who directed me to the Alarm reset button.
Problem solved.
This time not so easy, reset did not solve.
Not real sure where to start trouble shooting now. but have ideas and could use some directoion
My plan of attack
1. Check coil but not sure exactly how on this truck as there is no easy lead to hook a sparkplug to.

2.If there is Power check for fuel flow.Hate the thought of this. so find mechanic.
3 If no Power find way to diconect or bypass alarm. Is that doable?
2. next down the line is this thing on the FW that calls itself an ignighter again do not know how to check
Ok , any insight without getting to technical on me would be greatly appreciated
