05 Diesel long crank before start
I brought my 05 KR Diesel to the shop on Friday. The service advisor told me that it should only take 3 to 5 revolutions before the diesel fires. Mine cranks for 8 to 12 revolutions before it fires. It has 85,000 miles. The dealership does not know why. They have another truck same year and mileage with the same issue but they say is worse than mine. They have a call into Ford to help figure out the issue. This other truck they replaced the HP pump, and no difference. The pressure sensor checks out good on both trucks. Any ideas? I have only had the truck for 3 months and it has always cranked a while before it fired.
