gasoline gushing out from Fuel Injectors

[Graphfixz]

I took out my spark plugs out and went to crank the engine. when I turned the key for a millisecond gasoline exploded out and covered the bottom of the hood, went all over the engine and covered the floor. Can anybody help with why the injectors have fuel gushing out in massive amounts? Is this normal?

I am a newbie trying to get my 91 Nissan 240sx going again.

Thanks!

ok, so I just tried to check the oil levels by removing the the dipstick and fuel just poured out for about 5 minutes!

You're injector o rings are bad. This is normal for old car. Have them replaced. Z1 has a good kit.
