will grounding my fuel pump help
 

will grounding my fuel pump help stop my hesitation. it is already grounded. should i reground it with a bigger gauge and such.

Did you look at the grounding writeup in the archive?

Rewiring your fuel pump is usually to prevent a lean condition, not fix hesitation

no i someone told me it would though

that is mostlikely not the problem,
is this the 3800 rpm hesitation?
try adding grounds from engine to chasis, and from ecu to chasis. also make sure the ground wire under the intake manifold is tightend down
