Went for a good beating on the race truck then after a few good pulls it started running like crap. Sounded like fuel nock. Got back to shop and found out rail pressure was reading 0psi. Checked connector and pig tail at pressure sensor and all seams good. Where pulling tomorrow so need this fixed asap. Maybe a bad sensor. Also throws a low rail pressure DTC. I this p0087.
Thanks

You can pull the connectors off the ecm and do a continuity test on the wires to the fuel pressure sensor. If good, probably bad sensor.
