I have gone back over this thread and do not see the part about misfire codes. Are you saying you got eight codes for misfire on all eight cylinders? Did you drive back to the stranded car and read codes or pay someone to tow it somewhere and read them or what? Confused here.

Yeah, sorry bout that. It was another forum where I specified that it was throwing misfire codes on all 8 cylinders. But yes, I had it towed to my friends house then put a reader on it...but neglected to jot them down unfortunately.

Sorry, its a fuel pressure sensor, not regulator. Mine suddenly sprung a leak once. Small black box type thing on the end of the passenger side rail.

Have a look here https://www.jaguarforums.com/forum/x...-153085/page2/ and https://www.jaguarforums.com/forum/x...-153085/page2/

I believe the pump is a Pierburg 03T260 / 7.28177.01

problem solved

Unplugged the maf sensor and it started right up. Went to autozone and got a new one with a lifetime warranty for $85.00. Drove it home without incident. Think I'll keep an extra one in the glovebox from now on. Who knew it would shut the car down completely while going down the road?! Thanks to all of you who lent me their support on this one
