91 isuzu pick up sat for 2 years and now wont start

I\'d try 2 things. One, some, or many, motors and fuel pumps, even electric ones, need to be "primed".
You might try to figure out how to suck the fuel from the tank up to the motor somehow.
I do not necessarily mean using your mouth.
You could also take a rag and an air hose, and GENTLY blow air into the gas tank to "prime" the system.
Another thing is, is there some part of the engine where gasoline could have congealed or turned to gummy deposits preventing the gas flow?
This is why they suggest mowers and generators be run until they run out of gas before storage, to prevent gummy deposits caused by evaporated gas.
Be blessed.

My truck has been sitting in a garage for 7 years and want stay running

The very first thing you do is get rid of the gas in the tank. When petrol sits for a year or more, varnish develops in the tank and lines. Once you do that, add a fuel additive for cleaning out a varnished fuel system. Ask your local Auto Zone or whomever you go to, I would then check that you have fuel pressure to the fuel system by removing a line and having someone crank it for you. If no fuel pressure, the fuel pump has been glued by varnish. If you do have fuel pressure, then you should check the distibutor cap on the inside to free any corrosion on the contacts. Make sure the spark plugs are good, and if not change them. Hope this helps.

Wont start - One year old.

Did you leave fuel in it for a year? If so you need to thoroughly clean out the fuel system. Gasoline has a shelf life of about 30 days! After a year it is gummy varnish and caked up in in the carb. Always add StaBil to your fuels that are going to sit for a while.
Also mix your fuel with the proper 2-stroke oil, this is important. Finally always keep the gas tank on the saw full. Do not run it lower than half a tank!

I love my z it has sat up for 2 yrs, wont crank, a friend mac cked it and poured gas in carb? it cranked. he said it was a fuel pump, any way to tell for sure

If a vehicle has been standing for 2 years yuou need to clean out the whole fuel system because the fuel turns gummy and clogs up small passages, valves and jets.

The problem is probably not the bulb itself, rather the fuel orifices within the carburetor are clogged with old gummy fuel. Sometimes, just draining the old fuel and adding fresh fuel (properly mixed) to the tank and let it sit a few days, will allow you to pump the fresh fuel through the carb. If this doesn't work, the carb will need to be removed and cleaned. I also strongly recommend to replace the gaskets and diaphragms within the carb when it is cleaned. As fuel ages, it gets thick and eventually turns to varnish. In the future, make sure that you run all of the fuel out of the equipment, or use a fuel stabilizer. Stabilizer will usually keep fuel good for 6 to 8 months instead of the 60 - 90 days without it.
Good luck!

Not getting fuel

If the car sat for a year then the fuel pump might be stuck. Have someone try to start it while you smack on the bottom of the gas tank until you hear the pump run.

Try draining all the old fuel out and running fresh fuel through it.Dont try to dilute it as stale fuel turns acidic and corrodes everything it is in contact with.Fuel system may require complete clean out

I had a geo metro that sat a long time and the gas turned to varnish. You will need to drop the tank, clean out the gunk, put in a new fuel pump and and filter and flush the fuel lines out to the injectors.
