Engine Performance problem
1992 Jaguar XJ6 6 cyl Two Wheel Drive Automatic 98,000 miles
My 1992 XJ6 Saloon would not start. I brought it in for service and the mechanic confirmed it would not start. He removed the fuel line and turned the ignition to see if fuel was flowing, which it was. He re-attached the fuel line, turned the ignition and it started. He doesn't know what caused it not to start initially. It's now working, but I'm afraid the same thing can happen again without diagnosing the previous issue. Any suggestions?
