Default New engine startup questions..need answers QUICK!

What should i do about getting oil pressure? Dad says to push the pedal to thef loor to put the car in " flood start mode" so it doesnt fire the injectors. I dont have O2's right now or O2 sims. Would it be wise to even try and start the motor without these?

I've run without o2's before.. didn't do any harm. last time I had to prime it, I just disconnected the injectors and coil. Took a couple seconds, guaranteed no fuel or spark.

even better, unplug the opti-spark connector (not the one ON the opti, but the one mid-way of the intake)

with out a doubt no fuel, no spark!

to do it properly, use a priming tool at the back of the block before bolting the intake down. Otherwise, you could try what other have recommended using the starter.
