Fuel Pressure regulator. It's the round thing on the fuel rail that has a vacuum hose attached to it. Read more about it here:

It could be one of several things. First, make sure the fuel pump is running. Pull off the gas cap and listen at the tank while you have someone turn the key on. You should hear the pump run for 1-2 seconds then stop. If not, then you need to check to make sure there's power to the pump which could be the FP relay as mentioned earlier, or even the Inertia switch (a magnetic switch that triggers in an impact to kill power to the fuel pump) It can be sometimes triggered by hitting a hard bump in the road.
If you do have power to the pump, try pulling the vacuum hose off of the FP regulator and look to see if there's any fuel present. There shouldn't be. If there is, that's a sign of a ruptered diaphragm in the FP regulator. But it can be bad even if there's no fuel present in the vbacuum hose...that's just a sure sign.
And of course, it can be a bad fuel pump as well. They often seem to crap out at around 100K miles. It can be a PITA to replace simply because it usually means dropping the tank. I don't know how it is in the Contour, there might be an access cover under the back seat which makes the job a heck of a lot easier.

Well...I usually test it by the substitution method, by installing a known good one. (But I generally have a few spares of just about everything laying around...)
Some of the diagnostic methods I've read about describe ways of testing the FP reg. by disconnecting the vaccum line with the engine running, which totally ignores the fact that it can be the reason the engine doesn't run in the first place...
Read through this and see if it helps you a bit:

well i reset the switch. im wondering if i should try and unplug the power switch going to the inertia switch. i can run a jumper wire from a hot source and power up the fuel pump continously but it still will not crank. it willl crank only when i spray gas into the throttle body then it will run for a few sec' and thats it. thanks for the help tigerdan

Okay, try jumping the fuel pump at the self-test connector (as in the pic below)
Stick a jumper wire into the plug for the fuel pump as shown in the diagram, turn on the key and then ground the jumper wire. The fuel pump should run. If not, then there's a problem with the pump itself or its associated wiring.

Happy fourth of july FTE. Any way i wanted to post back on my results and you will never guess what it was! After trying another pcm,another fuel pump,a dozen diff relays, fuses 100 hours of trouble shooting a freind of mine came over with a scanner to scan it but first had me put the plenumchamber cover on the throttle body first, and it fired right up and is running great.. I never new this air intake plenum chamber cover had to be on for it to run.. dummy me.. anyway many thanks tigerdan. Haynes repair manual should add that little valuable bit of info in their manual.. thanks guys..

The only Contour I've seen under the hood of was a 4-cylinder, and I believe that's what everyone here has been referring to... (after all, this is the 4-cylinder forum)
I didn't know they put a V6 into the Contour, and I don't know which one it would be. 3.0 maybe...?
But your diagram on cylinder numbering should be correct. Your car is a '96, right? So it should be OBD-II which is DIS ignition and non-adjustable timing.
