Cylinders full of fuel
After thinking I had dropped a valve or broken a rod because my engine turned over a couple of times and stopped dead, I removed the spark plugs in an attempt to hand crank the engine.
As I removed the spark plugs, most of them had fuel pouring out of the spark plug holes.
Would this be attributed to faulty injectors or a faulty fuel pressure regulator? Or could it be something entirely different?
Thanks in advance guys. Rick

Most likely a faulty FP regulator. If it breaks, it can suck in fuel from the vacuum line, which goes into the intake, and then into the cylinders.
Pull the vacuum line off the FP regulator and see if fuel is in it.

My 94 has done that twice,fuel presure regulator the problem both times.
I now run an Aeromotive adjustable one.
If you find that is it. Just remove the tork screw where the white and grey round ends cover the fuel lines return and fuel presure lines with the metal bracket. Remove the tork screw on the FPR ,slip it out of the fuel rail with lots of raggs to catch the fuel.Don't lose the black "0" ring just incase the new one doesn't come with one.The factory FPR are realitivy cheap.

Make sure you disable the ignition if you turn it over to get the fuel out of the cylinders!
You might want to put a small amount of oil in the cylinders after you get the gas out and before you put the plugs in.
