have replaced plugs,wires,dist-cap and rotor button,new fuel pump assembly. still won't start.And yes tested coil and resistance is within range....can you test the throttle position sensor and could that make it not start? turns over fine,also checked timing chain..not broken.

Just finished doing the same to my jeep, and I came to find out that my CPS(crank position sensor) was bad. they are about 40 dollars at your local auto parts store, and replacement isnt hard just tricky.
To remove the old one your will need a 7/16 wrench or socket with a universal and extentions, its located at the top of your bell housing on your driver side. two bolts hold it in, just remove replace.

Before i would head off to buy a new part i would do the key trick to get the any code it may be reading (hold the odo button and turn key to on then off 3 times withing 5 seconds, your dash will light up like a christmas tree and and start counting 1 through 9, at the end it will tell you any codes you have 54* is the CPS if you get a 55 that means everything checked out)

Hopefully that helped you a little bit,
