When you go to start it the motor turns over but dose not start riteaway. and some times you have to pump the gas petal

Will it start and or run with a shot of carb spray down the throttle body?

can you hear the fuel pump running?

have you checked to see if there is fuel pressure?

it may be your fuel pump, take off your air cleaner and pump the gas with the engine off and see if you smell or see gas, then try it with someone turning the engine over and see if u can smell or see gas, if not your pump is probably shot

sending unit / fuel could be going bad or the fuel stock filter is getting pluged up when stir up the gas in the tank the sock is a filter inside the gas tank over the sending unit try changing the fuel filter out side the tank that could be pluged up.

you need 4 or 5 gallons gas to be on safe side.could be too late damage fuel pump.never run vechicle low on fuel.fuel pump needs gasoline to keep it cool and lubricated.add more gas see if engine run better.if not i would change fuel filter all sediment was disturb when you add gas to empty tank when you poured gas in fuel tank sediment break up stop up fuel filter.change fuel filter see if car run better if not more like fuel pump over heat and damaged pump motor bearing.

Try turning the truck to ON (not start) position and OFF position 3 times and then pumping the gas petal all the way to the floor 3 times.

If that doesn't work turn the key to the ON position and pump the gas 3 times, then OFF.

turn key forward (do not start motor). Pump gas petal 3 times, turn car off. Start car and see if this worked. If not, repeat.

sounds like its starving for fuel, bad gas in the tank, clogged fuel filter. that's where i would start. good luck

the pump is in fuel tank the filter will be under car near the fuel tank on left side

Well it was'nt the timing belt! Turns out it's all in the fuel pump. If i turn the ignition to the on position for about 5 to 10 seconds before starting, it cranks right up.

Try checking the snorkel tube between the air cleaner and the intake. Open the hood, and have a friend try to rev the engine, and watch the tube...my '92's was collapsing and starving the engine, couldn't get more than 3500-4000 rpm. Could also be a fuel pump problem like low pressure or bad line.
