I have a '90 Grand Marquis GS EFI 5.0.
Today something new started happening. The first start of the day is very, very hard. It cranks for about 15 to 30 seconds before it will start.
The car normally sits from around 6PM to 10AM the next morning just about every day and never had this problem. Every start after that first hard one are instant, all day long, like all of them used to be until today. Even the first start of the day was instant until today.
Maintenance on the car is kept prudently. I even change the oil every
1,500 miles. I have the car since it was new and I know every squeek.Most sensors have been replaced by now including the IAC motor and the EGR. Recency replaced oil sending sensor and coolant temperature sensor. Actually, the car runs great.
Right now this is the only thing that is not right, this hard morning start.
Any ideas on what might be causing this?
This NG has always come up with the right answer for me for a long time now.
Thank You!!
