Have a Car Question? Ask a Mechanic Online.
are you there?
sense the engine light dont come on,,the first thing to do here is to check the fuel pressure
these vortec engines must have no less than 60psi at all times
anything less may ccause this hesitation
i would think your fuel pump is weak
and may need to be replaced
this is a fairly common problem

I changed the fuel pump about 8 years ago and I can hear it running. Is there anything that will cause low fuel pressure?
even though the pumpis running..the pressure can be low...very common
these pumps can be bad,,new right out of the box
Hi thanks for your help so far. How do I check the pressure
there is a shrader valve just behind the throttle body that the fuel pressure tester connects to
connect the test gage
start the engine and give it throttle
the pressure should never fall below 60psi,,,,even while turning the starter
i would think you may need another fuel pump
OK Thanks. Can you think of any other reasons for the hesitation?
sense the engine light isnt on,the fuelpressure test is where to start here
there are many many things that could cause this
this is where to start
and ,is the most common problem
you are very welcome
