1994 Isuzu trooper very hard to start. acts like it flooded but when it finely starts it runs great and will restart every time. once cold it ether won't start or is very hard to start and acts like its flooded. you can smell gas and it smokes when it finely starts. after the engine clears it runs good and will restart fine. I'm lost

are you getting a spark on your spark plug????/

have someone kick at the gas tank while you are turning key if it starts it is fuel pump

The likely culprit is a fuel injector. If your injector is faulty or stuck open and allowing more gas than it should into the cylinder it will cause white smoke and enough gas will cause a gas smell and may end up soaking your exhaust system and cat converter. On mine after replacing the injector the gas in the cat converter took a while to work its way out and stop smelling and smoking. 
Pull your spark plugs and the one wet with gas is from the cylinder with the broken injector. Replacing that injector should solve the problem. However, if you're not comfortable working on the pressurized fuel system have a mechanic do this. 
Be sure if your do remove the injector to do everything to prevent any parts falling into the cylinder. On mine the injector had cracked and brittle plastic casing disintegrated and bits fell into the cylinder causing more headaches. 
Your'e supposed to replace all fuel injectors as a set to ensure idenical fuel delivery in all cylinders, as over time the jets wear uniformly. Adding one new injector with a new (narrower) jet can sometimes throw off sensors and calibration. However, I replaced just the bad injector and all was well.
Hope this helps.
