Need some serious help,

I have a '92 taurus that wont start when the engine is hot. If I let it sit for a few hours to cool down it will start. I've already changed the fuel filter, and the fuel pump. The engine has no problem cranking so I know the battery good.

Someone please help.

sounds like the pick-up has gone bye-bye, very typical

The car has spark, if you spray starting fluid thru the air intake it will run but really rough. Just tried the ignition coil yesterday and that still didnt help. No check engine light!

Im open for any more suggestions.

If, it is the pick-up they will have spark during the CRANK MODE , an then as soon as you let off the key it will die. However your saying if you put starting fluid it will run ( please be very careful thats bad stuff ) I prefer to use carb cleaner , an or WD-40. with the key turned on you should breifly hear the fuel pump relay click on an possibly the fuel pump humming for a second or 2 , If you look on the fuel rail you will find a schrader valve. ( looks like the thing on your tire that you add too ), Normal they have a cap on them , If you got 2 ppl, have one turn the key on , an the other depress the shrader valve it should shoot a good stream of fuel outta it , so dont get your face too close. It would be great if you a fuel pressure test gauge then you would know what kina pressure you really got . ( but I know the average guy dont have these ), if theres no fuel , you could have a bad relay , a bad pump ground circuit wire I ran into this many times they get a burnt plug in to the top of the tank , a bad pump roll over switch ( interia switch ) , usually you can temp. bypass these rite at the bottom of the switch with a jumper wire just to test them . Let us know what you find .

yep, might just be a bad fuel pump, you should check the inertia switch, and B+ & grnd at connector of the sending unit before replacement, could be electrical problem.
