There are several issues that might cause a hard-start problem. The
fuel pump has a check valve in it and it will sometimes go bad and
cause the fuel to leak down and then it will take several times to get
the fuel up to the engine. Also, this will cause a starter to overwork
and, in turn, wear it out. Also, a bench-tested starter is a parts
person’s hardest diagnosis as it is not always a true test of what the
part is really doing on the vehicle. So, it may still be the starter
beginning to drag or it could be the battery cables that are getting
weak.
