1. Why are electric fuel pumps
that are associated with fuel injection systems mounted in the fuel tank rather
than in the engine compartment?

A. To make replacement difficult
so as to keep the vehicle owner from replacing it with an aftermarket pump

B. To reduce the cost of replacing
the fuel pump

C. To increase the PCM’s ability
to diagnose the fuel pump circuits

D. To reduce the potential for
vapor lock within the fuel management system

2. Why is the PCM programmed to
de-energize the fuel pump relay if the tach reference signal is lost?

A. To guard against emptying the
fuel
