1997 ford Taurus dohc turns over but won't start.

Had this issue with a 98 v6 mustang, I replaced a lot of minor things like fuel regulators etc playing the guessing game, then went with my gut feeling, changed the fuel pump and started right up. This may or may not be your problem, but I figured my experiance may help.

Need to/Got to know IF it has good hot spark to the plugs, then how much fuel pressure it has.
