choking,sputtering, gasping- Bad fuel pump?
 

1) 2001 GM- cruising speed at 40-50 mph car is choking bad, acts like it is getting no gas, engine is sputtering and the car is struggling to move, but if I give it some throttle it will stop sputtering and goes like its suppose to. Cruising at 50-60 no problem.

2) Cold start in the morning the car fires right up, high RPMs. Levels off and drives fine. Warm start car takes 3 turn overs to start up, but always starts. A guy told me on the warm start turn ignition 3 times without starting and on the 4th try to start it....bingo fires right up every time.

Any suggestions? Is the fuel pump bad? Thanks for any advice you can give.

Choking, Sputtering, Gasping ??
 

The problems you describe suggest a worn-out Throttle Position Sensor.
I got a genuine Motorcraft T.P.S. at a good price from RockAuto.com .

The Fuel Pumps are practically bullet-proof, but a new Fuel Filter MAY be necessary.
Unless you KNOW that the Fuel Filter is fresh, REPLACE IT, and be sure to check the direction of fuel flow.
Good Luck !

Thank you for your quick reply. I like your words that fuel pump is bullet proof....I watched a you tube yesterday and thought....oh my. So, TPS I will change and fuel filter i replaced about a year ago, but with my issues I will do it again. And I have seen the directional arrow on that fuel filter!! Thanks again Merc. Kevin

About those Fuel Pumps -- Most in-tank fuel pump failures are caused by the pump overheating due to too low of a fuel level in the tank.
MANY people run their tanks down to the "E" before re-fueling, and the pumps need fuel in the tank to keep them cool.
'92 and other early Panthers had fuel-return lines that put unused fuel back into the tank, which CAN cause fuel delivery problems.
To avoid such problems, I always fill the tank when it gets down to 1/4th, which leaves a plenty of fuel in there to keep the pump cool on cross-desert runs
during the Summer.
Heat is a big factor here in the desert, and I've made several modifications to The 95 MERC to combat the heat's harmful effects, such as a B&M Transmission Cooler, Bosch Series 3 Fuel Injectors, Cast aluminum Differential Cover, and enhanced Air Conditioner upgrades.
