97 jimmy - 14 Oct 2006 21:13 GMT

I have a 97 Jimmy that will not build fuel pressure. If you give it
starting fluid it will start and run on the starting fluid but then die
when you stop feeding it. No pressure at the rail. Other symptoms I
have found are that the oil pressure gauge stopped working (Stuck on 20
PSI). The fuel gauge shows just under full and it only has about 1/4
tank. It will not come out of park. All these things worked fine until
the fuel issue. I have changed the fuel filter and found that it was
pretty well blocked off. I have read that there is a fuel pump run
wire under the hood. Is this true? Where would I find it? Any other
way to test the pump? I hate to drop the tank and change it out
($300.00) without knowing its bad. Especially since I have the other
symptoms. What other types of fuel shutdown safety/security items are
on this vehicle (IE. low oil pressure, inertia shutdown)?

You need to see a good mechanic. One possibility is a corroded ground point
or two. You need someone who knows how to diagnose the problem instead of
throwing parts and guessing at the problem. A good mechanic would be cheaper
in the long run.

I had a '97 Blazer that had a bad ignition switch, it would turn over and
everything but would not start because the ignition portion was not working.
Maybe you could look into that, is the fuel pump even running? You should
hear it run briefly when you first turn the ignition switch on.
