Re: LS swap fuel issues

The comments above regarding the ecm to control the relay is best. If you were in a collision the ecm would shut OFF the fuel pump because the engine died. I could only imagine a front end collision, hot exhaust, engine dies but the fuel pump continues to run from a switched key on relay and feeds a fuel fire to a molten glob on the road. Ouch!!
