it starts , but need to pump it

well again , let me start out with

when i got the car everything ran fine for about 1 month then i started going down hill

things i have done , most of all sensors changed with new ones , tune up , cap rotor plugs wires , water pump , timeing chain , alternator ,raidator(sp?) , time belts , and what ever the hell the part is them belts are hooked to (forgot what its called to tired to remember) new TBI unit 750 cfm , hoses , battery , and other smaller odds and ends

but after about a week of it starting like **** i did a few of the things listin above , now when the cars running its running fine you can give it gas and it goes you can rev it and it goes it just has the hardest time starting up which is a big problem

casue i crank it over about 2 times and it wont start and by the 3rd time my battery is dead and nothing in the car works , now i am thinking starter or fuel pump , the fuel pump the guy i bought it off of said it was only a year or less old and the starter 2 years , i am realy starting to give up on it casue i need a car that can at least start right (and say if my timing is off would that have any factors in this not starting right casue it dont shift right but the guy i had look at it says its fine and he is a good friend of mine but it still dont like to kick into 2nd)

does any one know were that shop in vermont was that looked at 3rd gens ? casue i know i can get it up there but i dont know if it could handle the drive back right away

Did you get bigger injectors with your TB? If so that probably has alot to do with it. You may try swapping your stock TB back on and see if that fixes it. You don't need a 2" TB on a stock 305, and most of the time it causes problems without tuning.
