Engine Mechanical problem
1998 Jaguar XJR V8 Two Wheel Drive Automatic 90,000 miles
My car is rough starting after sitting for 6-8hrs. It will crank, and if lucky, fire on the 2nd or 3rd try (sometimes not at all). Once fired up, it will start right away and run good as new for the rest of the day (until it sits for another 6-8 hrs). This happens even on warm days.
So far, I've replaced the coolant temp sensor, MAF sensor, and spark plugs. I've had the battery and fuel pressure tested - battery is fine, and it is not losing fuel pressure. Compression is also fine. So far two mechanics have not been able to figure it out. Sometimes after work I am left stranded in the parking garage. I should also point out that my engine was recently replaced (with a used engine), and this problem has been there since day#1 with the " new" engine. Please advise (thanks!).
