Well...it is the Fuel Pressure Reg thing on the bottom of the fuel pump.

Huh?

Are you saying that you aren't getting any fuel? Or are you asking if the regulator is on the fuel pump?

The regulator is on the driver's side of the fuel bowl on the top of the engine. It's located inside the cap right where the fuel return line plugs into the bowl. The regulator shouldn't be the issue since those are pretty foolproof for failure. The spring inside gets weaker over time, but they don't generally go out all of a sudden.

I might be saying the wrong thing.

It is something (switch, sylinoid, etc..) located at the bottom of the fuel pump. That's how it was described to me at least.

Does this make any sense to anyone?

Not to disagree but a better way to check the fuel flow is to open the filter lid and make sure it is full. If it is, you at least have some flow. If not, there you have it. Next, close it up and place a suitable container under the drain valve line that "YOU DO HAVE A HOSE ATTACHED TO RIGHT". Open the valve behind the bowl and let the bowl drain. When it stops, turn the key to the WTS position and observe for flow indicating the pump is trying to fill the bowl. Not a trickle, a flow. If not, problem. Remember, the pump will only run for about 30 seconds or so unless you start it or switch the key back off then on.

Uhm no. Who told you that? There is no such thing. There is a reset switch behind the passenger kickpanel and a regulator on the side of the fuel bowl which when it fails will lead to excessive pressure and premature pump failure but I highly doubt this is your problem. Aside from that it is fuses and wiring.

EDIT: to put your mind at ease, the pump is mounted on the inside of the frame rail under the driver seat. Have a look. If you find that thingy you're talking about let us know.

This is what a mechanic is telling me. He was referred to me by a friend, and is supposedly a trusted guy that has done a lot of work for him.

I need to call him in the morning to go over again exactly what he is saying he's replacing.

I'll post again in the morning to tell you exactly what he says. I don't want to get screwed!!
