97 discovery suddenly wont start. Tries to, just wont turn over. Problem getting gas? or worse, and ignition computer? Anyone give me some pointers?

 

Fuel has nothing to do whatsoever with the engine not turning over, or cranking.
Is your starter relay clicking when you turn the key to the start position?

 

You need to be more accurate in your threads, is the engine not turning over at all when you turn the key, or is it turning over and not starting?

 

IT turns over. Sounds like it will start, just wont. When this happenned, I turned the key and it started but when I let off the key it stopped and wont start since then. I dont hear clicking when I turn the key to start possition. I dont think I turned the key all the way like I normally do. Everything has run perfect up til this.

 

OK I just tried again. I do hear a click near the passenger floorboard. Is this the fuel pump relay? I opened the gas cap and put it back on, and I turned the key to the on possition a few times before trying to start. Just cranks, wont start!!!!!

 

I would look at the crank sensor as one possibility. When they fail, the engine will turn over but will not get fuel and or spark.

 

Are you getting fuel pressure to the rail? Are you getting spark to the plugs?

 

X4!

The gas cap has nothing to do with this.
Press the little tire valve on the engine fuel rail with a screw driver, if fuel squirts across the driveway you have fuel pressure.
If not then you have a fuel delivery problem.
If yes then you have a spark problem and you need to remove one spark plug and hook the plug wire back up and have a friend crank the engine over while to check to see if the spark plug sparks.

 

Checked the valve on fuel rail. No fuel comes out, none! Now what?

 

Check your pump fuse and relay, if they are good, and assuming the pump is good, then I am still leaning towards the crank sensor.
