Question about 2003 Chevrolet Silverado 2500HD

1 Answer

Hard starting My truck has become hard to start in the last few weeks. It takes a few cranks sometimes when it is cold to get it to start. My mechanic checked it out and could not find anything wrong. It is now doing it more often and sometimes when the engine is warm.

    My mechanic told me the spark plugs should still be good since the truck only has 51,0o0 on it. I was thinking maybe it was the fuel filter as well.

    i would check plugs,u have a 2500 so i assume its a work truck and is more often under load ,so motor will be working harder than normal,so maint. will be done sooner,i would change fuel filter,and pull out a plug or two and inspect gap and wear!

I would load test the battry, just because it has teh voltave it may not have the origional amps, common problem overlooked, if it goes down to 7-6 or below just on the volts with a volt meter at the moment your starting it, you then know you have a problem with the battary,

I just had the same thing happen, i overlooked the problem until shopping with the wife, never again will i tale for granted 12 volts or more running or not, means its good.

also they are made to run with a certian amp to the injectors, when starting and if the battery is bad, it goes to the starter, and takes longer for the fuel to get in the cyl to fire up.

hope theis helps

At first the truck idles extremely rough when cold cranked. This went on for a couple of days, now the truck will not start at all. It hits every once in a while while repeated cranking on cold start. ...


Sometimes on cold days if the cranking amps on the battery are low, then it will be hard for the vehicle to start. Also, check the oil level. If the level is low it will create a hard start and rough idle for the vehicle.

Hows your oil level?When was the last oil change?May take more to get it started if oil is low or old.Oil turns to syrup in the cold.

Another possobilty is the cranking amps of the battery or the amount of power it will put out. A higher cranking amp battery will turn the engine more efficiently.
