OK this goes back to almost seven years ago. I had brought up for discussion about my car with 1500 miles not starting once motor got hot. Well 7 years later and as I found time to mess with it, my mechanic thought it was due to stale gas. I decided to remove all existing gas, replace fuel filter, replace injectors due to o-ring leaks. Now the car will not start cold or hot unless shot with starting fluid. It will run perfect once it is started. Does anyone have any idea of what is going on? We have replaced cam sensor and plugs also. Now the car has 1556 miles on it.
