I Stopped At A Store To Make A Purchase, The Car Was Running Great. About Ten Minute Later When I Came Out From The Store And Tried To Start...

When Exiting From Freeway Car Just Cut Off And Now Wont Start. How Much For Electrical Work For This Vehicle?

1998 Mercury Mytic Engine Cranks But Will Not Start. Fuel Pressure 35+psi. Not Sure Where Else To Check

A Week Ago, My Car Quit Running And I Haven't Been Able To Diagnose The Problem, Not To Mention I Lack The Tools To Properly Check It...
