inertia switch

[jick.cejoco]

thanks jick, that will be equally hard to find here. i had a gm with failed fuel pump relay driver (from pcm) i explained to the customer that if i will ground the relay and i will need a shut-off switch if i'm going to hack it. customer doesn't approve the idea and doesn't want to buy a new pcm so i sent him away.

the pcm driver for the fuel pump relay is only used to pre-pressurize the fuel rail for 3 seconds. when the engine starts, the oil pressure switch takes over to keep the fuel pump running. i.e., if the vehicle is a genuine g.m. product and not a korean daewoo labeled and sold as a g.m.
