What is the fuel pressure as soon as you turn the key "ON"?

So, the starter engages and you have spark (how do you know?) and have no fuel injected (how do you know?); the wing likes to go up, which is a sign of a weak battery/bad battery terminals.
I'd be interested in knowing the fuel pressure, if it is normal (58psi +/- 5 psi) then it would appear the injectors are not firing. If you have spark, your cam and crank sensors are OK, and you should have fuel being injected.

I really wonder what the fuel pressure is.
