S10 trying, but failing, to start

[quote:8f0986de87="jason&jena"]I have a 1999 Chev. S10 w/ the 2.2 4cyl that has yet to give me any huge problems, even after 206,000 miles. It started and ran fine as recently as one week ago today when we returned from a long trip. Upon trying to start it today, I found that the serpentine belt and associated wheels start to turn (for maybe a second) but then stop. There is a continuing hum (louder than the fuel pump) until I release the key. There also seems to be a slight jolt from both the engine and directly under the cab as the engine stops cranking even though I tried to start it both in and out of gear.
To reiterate, the truck started fine, sat for a week, and now won't start. It does not appear to be a starter or a power problem as I have experienced both in previous cars, but then again, I am not the expert.[/quote:8f0986de87]

I will check the fuel system 1st, start by checking the fuel pressure to rule out the pump/regulator/fuel filter-EFI don't like inaccurate fuel pressure.

When key is in On position -you should be able to hear the pump come on for a few secs. No sound could be a power issue or the pump itself.

If there's no fuel making it to the injectors-try priming it with gas or starting fluid if it starts and dies-the injector/s is either its not being energize by the computer or there's no fuel pressure.

Get these done and get back with me we still got a long way to go.

Checked and cleaned the battery connections, still working on how to check the fuel pressure, and no change in condition. Is oil in the spark plug wells any indicator that helps? I understand this is very broad and basic info but I'm am a complete novice and my friends with auto savvy have been unable to come look at it as I've been out of town.
Again thank you for your help thus far and I would appreciate any input from anyone with insight on the subject.

There's a fuel pressure tap/schrader valve that looks like a tire valve somewhere up from of the engine maybe on the back of the engine-not familiar with 2.2-however if you can locate the fuel filter and backtrack it back towards the engine, you'll run into it.

TBI pressure 8-12lbs psi

Once I got someone over to listen to the problem it became evident to him that the cellunoid on the starter was toast. Just for anyone else's reference who may be reading this for help.
