95 Bronco won't start

Jeff,

I can't be of any real help, except to mention that ceativity might pay dividends. My 90 Sentra needed a new fuel pump a couple of years ago. IIRC, Chilton said to drop the fuel tank, but the shop I had deal with it ended up quickly yanking the back seat to get access to a panel, and did the job through it. My hunch is that they worked through both the cab and the trunk, but it saved them dropping the tank.

The pump's in the tank, Jeff, and you'll have to drop the tank to get it out. It's pricey if the pump is the problem.

Spd,

I'm looking at this late, but, aren't there two pumps. The one in the tank and another 'in-line' high pressure pump mounted somewhere on the frame rail?

I haven't found this to be correct in my Bronco. I only have one pump that I know of. If there's a second pump, it is not shown on the wiring schematics, nor is it obvious when looking at the frame rails. I'll double check, but the first glance did not reveal a second pump. Thanks for the thought though ...

Just one in the tank on that truck, and a fuel filter on the frame rail.

Jeff,

I was mistaken. I was thinking about an older truck that I used to have.

The Trouble Code was 542, Fuel Pump Circuit Open (with a detail about the ground-side that I forget at this instant).

I replaced the fuel pump and fuel filter for $198 in parts, and a few beers for the labor of my brother in law. There were three other codes that were all red herrings (false codes) that had nothing to do with reality.

Bottom line, it was a relatively easy job that required more muscle than technical expertise.
