2000 Cadillac deville. No start problems. Car will turn over

Customer Question

2000 Cadillac deville. No start problems. Car will turn over but never start. Will pop off(or false start) occasionally but never start. Have checked battery, fuel pump, power to fp, ignition/coils has spark, has compression, no security light on, all fuses good, have energized related relays to test. No codes being shown. Do not own car, so don't know what originally caused car to not run.
