Well the old 89 Bronco 2 died yesterday. Classic case of fuel starvation; just coughed and belched when trying to restart. Got zero fuel pressure in the injector rail. Searched and finally found the pump relay (quite an accomplishment in itself) and confirmed it is working and putting out power. Checked and found voltage on both sides of the impact switch. Checked the ECA codes and got a 95. That means something about fuel pressure but I don't know what. How would the ECA know there is no pressure ?? When I turn on the ignition I don't hear the pump whine for the traditional one second or so to pre-pressurize. Have not checked for voltage at the pump yet. Fixing to drop the tank (which Mom just filled) to pull the pump and test it. New pump - $125.00 - ouch !! The pump is original with 140,000 miles on it. How long should they last ?? Any theories before I rip into it ??
Thanx

 

Hi, if it is the pump, try going to http://fordpartsonline and see what they want for the pump they have been very good with parts for me and when I told Gary about this site he said he would check it out would be nice to have parts on line to go with answers on line huh? John

The saga continues. Dropped the tank today - what a nightmare. Took an hour just to remove the undertank shield - that was the easy part. In order to get the push connectors off the unit you have to be a pickpocket - needless to say, broke one of those boogers. Finally got the tank out and removed the pump/sender assembly. The pump is encased in a plastic puzzlebox - who designed this - Houdini ??? Finally got that apart - the whole project is a big mamuska doll. Time for a beer. To be contiued.

 

I have that problem with my 86 B2. With mine, it ain't the fuel pump. No damn clue what it is, but I'm guessing a short in the steering column somewhere. Right now, it's jerry-rigged under the hood, with a wire running from the fuel pump plug to the ignition plug. What happened with mine is, sometimes it will shut off when I turn the key off, sometimes it keeps running. And, sometimes if the wire ain't plugged in, the fuel pump don't start. So I jerry-rigged a switch to turn it on and off.
I've narrowed it down to a short in the steering column tho. Because, even if I don't start my truck, and just the key on to accessory, and then turn it off, the dash doesn't turn off like it's s'posed to (4x4 light stays on, along with fuel gauge).
Might be something to check into anyway.

 

Gimps, your ignition switch may be bad. I have had similar problems with a Mustang, and it turned out to be the switch. They use a similar switch as the BII.

Mission Complete !!! Got the new pump in and fired it up tonight - runs great. A few lessons learned. New push connectors cost $21 each. I used a Doorman product. This was my first experience with plastic fuel line. The new connectors come with 18 inches of tubing. The way to install new connectors is to put the plastic tubing ends in hot water for ten minutes and than push in a barbed nipple (whew). The real discovery was that the best way to disconnect push connectors is not to pull the nylon horseshoe clip but to use a plastic tool much like is used to separate AC fittings. Need to know that the pressure fitting is 3/8" and the return fitting is 5/15", also, all tubing is 5/16". All 1989 and later Bronco 2s only have a high pressure pump in the tank. Earlier models have a low pressure pump in the tank and a high pressure pump on the chassis rail. Seems most electrical fuel pumps get noisy before they fail. Not this one. SWMBO was driving when it failed without notice and forced her to dead-stick to a convenient parking place. Put 12 volts to the old pump and got nada, nichts, zip, zilch. The suspense is too much - got to do a post mortem tomorrow and see was cost me 152 big ones.
