Slow starting

I have a 2000 Chevy Silverado 1500 5.3L automatic. It is a 2wd 3dr. It has 90000 miles on it.

The battery is good. The alternator is good. The starter is working. I have replaced the fuel filter. It will start after pumping the gas. I can shut it off and it will start immediately every time. If it sits it will take several tries to restart by pumping the gas.

I suspect the fuel pump, costly. Is there any other ideas as to the problem. I have only gone through 2 sets of tires and one battery in 7 years. Never had any problems before.

Appreciate any ideas.

Check the fuel pressure-could be a FPR/PUMP/leaking injectors.

You need a fuel pressure gauge or try this pinch off the return line and see what happens.

When a fuel pump goes out it can do so one of two ways either it can quit and stop working or it can fail intermittently causing the engine to stall or not start.
