Hello there

Customer:

hoping you might be able to point us in the right direction

Ron :

There are 2 fuse to check, the #11, 20 amp in the under hood panel and the #16, 30 amp in the under dash panel, you also need to make sure that the black/orange, the red and the lite green/reds wire all have 12 volts while running at the connector on the alternator. See the enclosed diagram. Check them and let me know.

Because of your expertise, you armed me with enough ammunition to win the battle with the dealer. They are installing a fuel filter and fuel pump at no charge to me.

I do know, after going though this with JustAnswer, that I can somewhat trust my mechanic but I will always contact you prior to going there.
