I'm surprised there is not a write-up in the cave.
You can either buy a pressure tester or borrow one from a parts store. Don't know what you have up North but Harbor Freight has a kit for around $20 if you want to own one. Canadian tires is a bit more expensive. http://www.canadiantire.ca/...er+Kit.jsp?locale=en
You screw the tester on your fuel pressure schrader valve on the fuel tree by the thermostat housing.
Cycle your key without starting and you should hear the fuel pump run for around 3 second. You might have to cycle it a couple times or jump the fuel pump power on the aldl connector.
You should have around 42psi. The pressure should hold at that pressure for a half hour or so on an really good system.
If it drops off quickly or in 5 min. or so then you have some kind of leak.
You then have to determine where the leak might be. Possibilities are.
Fuel pump check valve, leaking injector(s), bad fuel pressure regulator, unlikely plugged fuel pressure.
If you don't get near 42psi, then bad regulator or fuel pump.
Wrap locking pliers jaws with tubing or something to protect the rubber fuel line behind the engine. Clamp off the return line, (one without the filter) Cycle the key again. If you get more pressure then you regulator "might" be bad. OR If you get pressure and it still leaks down injectors are leaking, check valve is bad in pump or you don't have the hose clamped off well enough.
Next, with help cycle the key and also clamp off the supply line. Pressure drops your injectors are leaking.
Think I hit it all. If I wrote something wrong it will be corrected by someone I'm sure.
