Does that model have the external starter solenoid like the old Fords? Is that what you jumped to get it to start?

sounds like bad ignition switch

To be more exact. The 2005 has the key on the column. The switch is likely ok. There is a metal rod that goes down the column that pushes and pulls a plastic rack with copper contacts embossed on the rack and rack case. The start part of the rack is the furthest position down the rack. The metal rod slowly wears away the inside of the rack from years of cycling off-ignition-start-ignition-off. The switch likely is moving the same as it was when new, but the rack just isn’t sliding far enough to make good contact in the “start” position from wear.

Time for a new ignition rack assembly. Last time I changed one, it was a few plugs and a couple nuts. The one I changed had some adjustment in it, but not enough.

It’s about $70 for all the parts to replace the plastic parts and the rod

Is there more to replace than just that part you have a picture of? If not I can get a standard replacement online for about $30

There is a rod that goes from the key tumbler down to this part. It generally doesn’t wear out, but it might as well get replaced when you do this part.

Was that something you were able to replace yourself?
