Engine Performance problem
1986 Jaguar XJ6 6 cyl Two Wheel Drive Automatic

Acted like it ran out of gas, would start momentarily but die as if out of gas. Replaced fuel punp, fuel filter, blew out lines, replaced fuel pump relay and cold start relay. Will not start without ether but immediately stalls out. Should I check if the injectors are getting signal (& how) or is there something else I should be checking.

Hi there,

Thank you for the donation,

The first thing we need to know is the actual fuel pressure readings, are you in a position to get a rail pressure test done?

OK. Also have you done a scan for any unresolved fault codes as well?
