hard time starting

is it efi? if it is, make sure u prime the pump b4 u crank it, and DONT push on the throttle!!

my 2000 gmc will start sometimes on the first crank but a big percentage of the time on the second or third. im thinking either the plugs or distributor cap. what do you think?

fam5, I would start your diagnoses with the fuel system as I recommended to joesmith previously. It is allways a good idea to make sure fuel pressure is correct and holding when diagnosing hard starting or extended cranking issues.
