My 2000 1500 Silverado has issues. It starts fine, but when I press the gas pedal it sputters and chokes. I can drive it and have no problem maintaining highway speed, but I know there is a problem. I can stop, shut it off and upon restarting I have to let it run for about a minute, or it will hesitate when I try to accelerate. I mean it will gag and cough, I can throttle it and it will stop acting up. I attempted to back the timing off but upon loosening the bolt that holds the distributor I find that it will not rotate like they did in the good ole days. Is it bolted down in a fixed position, or is this not right? I have thought about the fuel pressure and filter, Thought about a dirty throttle body, alot of thinking. I am still leaning towards the timing. Hope you all can help.

You either need to change the throttle position sensor or the gas pedal I got a 2008 Impala I had to put a new gas pedal in in so it would function properly

check the choke control

You need to rebuild the carburetor or clean the choke linkage and make sure the choke valve closes cold.

have u checked into getting new sparkplugs, wires, coil/coil packs distributor. could even be a timing issue. id start at these things and c if it helps

I would check the choke for proper operation , remove the air cleaner lid and see if the choke butterfly valve closes when you press the gas pedal down once with a cold engine, if not clean the choke blade and the linkage that close it with carb cleaner spray.

Sounds to me like your choke is malfunctioning. Take the cover off of your carb when cold and see if the choke (top buttefly valve) is closed. It should be when cold. (you do not say what year truck you have so I am guessing as to the answer)

Most likely a lack of fuel, check the fuel filter first.

Gasoline- thank you. Warm up is not an issue like diesel is. Sounds like the choke is is either wide open or over choking. With the engine cold, remove the air cleaner and note where the plate is at the opening of the carb. If it is wide open then without touching anything else and engine not running, step down on the gas pedal and see if the choke plate reset itself to restricter the carb inlet. If it didn't, then take some WD 40 and spray the linkages and the rod ends holdin the choke plate.By hand work the plate and linkage holding the gas open at the carb. Then set the plate to wide open and do the gas pedal thing agan to see if choke sets itself back to restricting the carb intake. If it does, start the engine and as the engine warms upm the choke plate should start opening on its own and you are off and running. Roitine question. Is your air cleaner clean? If the choke plate needs adjusting. get back to me. K? Good luck Remember to press the gas pedal down once before cranking. That sets the choke for cold start. Hope this helped you Good luck Note, the WD40 won't hurt anything but avoid spraying with engine running or when engine is hot..

no gas in the engine
faulty tank switch if you have dual tanks
in tank something blocking the filter
fuel filters clogged
3 filters
one in engine
one located on chassis by gas tank
one located in the tank called sending unit this has filter on it
fuel injectors need cleaning
alternator
