'95 EB Will not start

[plex4r]

My 1995 EB has been hard to start for a few months, especially when it is cold in the mornings, but it always has started. After it sat for a week without running, it will not start.
The fuel filter was old so I replaced that and verified that it is getting fuel. (The old filter was clogged. I could not get air through it.)

The battery is charged and the starter is spinning the engine rapidily.
I verified that that plugs are getting power, by removing a plug wire near the distributer and watching it spark.

I tried to run the Key On Engine Off test with my ECC scanner tool, but nothing happened. The scanner light just stayed on. Any ideas on what this means?
Also, when I turn the key on I hear a sound from the rear of the car, probably the fuel pump. It does not stop and I can't recall this being the case before. Does this sound like a problem also?
Where should I start?

(No flames for this please :-), but the plugs are probably the original ones. Should I just start by replacing the plugs and possibly the wires?

Could be plugs, but I'm doubting that plugs went bad all of a sudden while parked. They should definately be changed if you plan on keeping the vehicle. You did mention that your filter was changed and that the other one seemed clogged. Make sure it was installed in the right direction and make sure your line's not leaking. If the sound you are hearing is a humming sound, sorta like an electric motor, this is probably your pump trying to prime your fuel system. It should go off after a few seconds. So you could be looking at a bad pump. You would be better to do a fuel pressure test to see if your pump is up to par.

Thanks for the help. I have wires and plugs so I will change this.

I verified the filter is in the right direction. I left the arrow in a visible direction just to be able to check this. Also when I removed the fuel line by the engine, after the filter was installed and after trying to start the car, fuel sprayed everywhere. I agree that I need to test the pressure. I'll report back.

Thanks, Bill.
