You will need to do a fuel pump pressure leak-down test, the pump must not loose more than 5 PSI overnight, u will need a cheap fuel pressure test guage, the test port is on the fuel supply rail to the injectors on the intake manifold, it looks like a tire valve but metal with a plastic cap on it, u may be able to borrow this guage from Kragen, Autozone or a parts store like them, if not they are very cheap, less than $20 US. Run the engine with the test guage hooked up, turn off the engine and then check it in an hour or so, if it drops more than 5 PSI then u will need to replace the fuel pump in the gas tank. One note make sure the connection for the guage is tight with no leakage or the test is invalid

I just went thru a similar problem. When I changed my fuel filter the problem stopped. I can't say that it is the exact solution for your problem. But it is a cheap fix if it is. You can remove the old one and tell before you buy a new one. The filter is located in fron of the gas tank. It comes off easily. If its clogged then replace it. ( I recommend replacing it evey year anyways). There are a few other possible problems that it could be. I hope this helps

generally your problem can be traced to a faulty anti-drainback valve in the fuel pump. After sitting for an extended time fuel must be re-filled and pressurized before engine will start. Second primary cause is a leaking fuel injector which does the exact same thing from the other end of the system but, this is also accompanied by a puff of smoke after starting.
Other causes can be low comrression from engine wear, or, a weak ignition coil but these are far less common.

I believe you have a throtle body correct? IF so you have poor fuel pressure, plugged filter of injector.If by some miracle you have a carberated engine the the fuel is leaking from the bowl. Get a carb rebuild kit.
