1992 cadilac eldorado won't start, engine turns over

....and you suspect fuel pressure because you had someone pull a sparkplug wire and put a screwdriver in there and held it close to ground...so there was a spark?

when you turn the key to the ON position, the fuel rail should become pressurized....you may push the Schroeder valve to have it squirt fuel at ya if this pressurizes when the key is turned the ON position....an inertial switch could be the case if someone tapped the bumper hard...or if the car came to a "brick-wall" stop job~

air/fuel/spark/timing....and valve timing...we must have all these things...take it slow...we can test for any and all these things~
