Troubleshooting the relays

[DAVVIL]

Hey all,

Please correct me if I'm wrong, but the relays are the two cables that go connected to the ECM, right?! I'm trying to troubleshoot the fuel relay... according to the dealership I have a defective pump, and I'm not about to drop $3k for the repair... now, with that said, I'm not mechanically saby, but I'm not completely ignorant either, specially when they say I need to spend $3k for the repair. If I invert these two cables I should be able to find out if it is the pump or the relay... Thanks in advance

Bump... anyone?!

On the lightning, I believe the relays and fuse box are under your seat. Should be two relays, one for the starter and one for the fuel pump. If you think one is going bad, swap them, they are the same. If you're mechanical you can jump the relay post on the relay and check for continuity across the contact post with a multimeter.
