I have a chevy 2000 z71 truck. I think something is wrong with my starter. The motor starts but it seems to turn over slower than normal, and I have to give it gas, then the motor responds and starts.

When you step on your pedal you are not giving it gas.This is fuel injected.All you are doing when you step on the pedal is opening the throttle plate and moving the TPS.In effect, it's more of an air pedal.You are thinking of the old carbeurated engines.I suggested that you have a load test AND an Amp draw test done to check the condition of both items.Do you have your own load tester or multi-meter?If so ,you can set your meter for DC volts,hook it to the battery and watch the volt drop while cranking.If it drops below 10Volts you have a problem with the Battery or starter circuit.Not a big problem obviously because the vehicle still starts.But it would be wise to catch it before it may become an issue.If you are interested in learning about fuel injection and how it all functions I would be happy to provide you with some links to assist you in understanding things like ,what happens on a fuel injected engine when you press the accelerator pedal.Now,if you just partly open the throttle and start it,what happens?If it starts easier you may only require an intake cleaning.If you look into the throttle bore, at the plate, and see black gummy substance, this is a problem.You can purchase intake cleaner (NOT CARB CLEANER) and follow the directions on the can for cleaning the intake and throttle body.This service performed professionally does a much better job and restores lost performance and is just good PM (Preventive maintenance)anyway for fuel injected engines.Good luck.
