i dont think its fuel pressure related. it could be o2, map, or if it has it maf. my jeep was running really bad without a cel so i thought i yanked the wires out of my o2 when i was on the trail. they looked good, but the upstream o2 was literally in 2 pieces from age sure enough after i touched it cel came on. replaced the sensor and its been fine ever since.
