1999 XJ. Cranked at first but would not start. Sounded like there was no fuel. Checked the TPS connection and manually opened the throttle body butterfly a couple of times and cranked it and it started and ran. Drove it for about 2 miles and it cut out without stuttering and died. Pulled over and went through the same process and got it started again. No trouble codes. Any ideas on wether it could be TPS or CPS? Thanks
